So, it's x = 5/0.8 ?
not divide by 0.8?
0.8 = 5/x; x * 0.8 = 5/x * x/1; 0.8x = 5; x = 5/0.8;
That's how I got there.
Can I please get a thumbs up or down, and I can close the help. Don't need a walk-through, just whether it's right or wrong.
i think he meant divide by 0.8
yeah its divide by 0.8
looks good
sorry for not responding sooner
its just i was thinking on terms of the "multiply by the reciprocate of the fraction"

i am having trouble understanding this question
the parts under say this:
deepest section of the lake has an area of 57.93km^2 and a depth of 350m
second region of the lake has an area of 47.51km^2 but a total area of 105.44km^2 and the new section has a depth of 300m
third region of the lake has a total area of 190.24 km^2 and the new section has a depth of 250m
fourth region of the lake has a total area of 372.66km^2 and the new section has a depth of 125m
fifth region of the lake has a total area of 579.07 km^2 and the new section has an average depth of 50m
and what i dont understand is why it gives me the total area for the 2nd, 3rd,4th and 5th region
@clear magnet Has your question been resolved?
i still don't understand after 20 minutes if searching
What's the question the book is giving you?
it's asking me to figure out the volume of a lake
and its giving me the area of each section
in a very confusing way that i don't understand
and i am not sure how i am supposed to find the volume for each section if it's giving me the total area of every region

hi thee
hi!
how did you get that T3
taylor series
of what tho?
taylors series of which function?
keep it
for this we need the series of e^(-x^2)
do i multiply it by everything?
i just put 0.3 into -x^2 and got -0.09
to counter that
then i can just use e^x
oh then okay but I hope you made no sign mistake
my TA checked that part so i think it’s fine
you haven't used parenthesis
i jusg need to know what to do w the 1/rad2pi . do i multiply it by the whole series or like
like (-0.09)^2
yes
ah okie
you just multiply to the value you get after finding T3(-0.09)
okahy

Yo, im not really sure what this question is asking from me. Do i just use first principles?, do i have to take the limit from both sides?
Limit of the difference quotient
yea, try using the definition of the derivative
That's exactly how you do it
.
show that the limit of the difference quotient is the same from both sides
whats that
In this section we define the derivative, give various notations for the derivative and work a few problems illustrating how to use the definition of the derivative to actually compute the derivative of a function.
oh right first principle
sorry i just havent heard that phrase before
ok so now how do i do that from both sides
hellooo?

@willow wraith Has your question been resolved?
can you show the question?
Find the length of the curve
well I can't figure out what you have written for x and y
2s look like Zs
y= 2t
yeah
there is no z anywhere in the question
stop that habit
no it's not same thing
brother can we get to what I did wrong and not my handwritting
That is what you did wrong
you want I can type it out
You are lucky to not be saying thatt to other helpers
Why is 0<=t<=1 but your integral limits go from 0 to 2
well thats what I did wrong
what is riemann asking above?
no he found the mistake
maybe if you see that you'll understand
It was hard to find because of your handwriting
you can see answer in that question

This is from my elementary number theory class:
We recently learned about the Chinese Remainder Theorem, but I'm not entirely sure how that's related to this problem. I know that one million consecutive non-perfect numbers exist somewhere, but how do I show that?
a^2-(a-1)^2=1000000?
I actually considered just writing that, but it seems too easy... is that really the only logic I can apply here?
If It Works i dont see the problem
That's fair...
Hm, then, what about the next one? Also related to CRT:
Wait, nevermind. I think I see the solution. Thanks!

Find the remainder when $17^{101}$ is divided by $20$
oh my
Bad Tex
is there a reason you're binomial expanding this
^
I wanna do the problem using binomial expansion
there are much better ways of doing this problem
what you are doing is painful
also all the -17's should be -3's...
Oh shit yes
best case scenario: you realize that all but the last term are multiples of 20 and end up saying in a very longwinded way that 17^101 = (-3)^101 mod 20
worst case scenatio: you agonize over the hundred and two terms, trying pointlessly to calculate each one
Ok so all the terms in the binomial expansion is divisible except nCr(101,101) (-3)^101
What do I do next?
best case scenario: you realize that all but the last term are multiples of 20 and end up saying in a very longwinded way that 17^101 = (-3)^101 mod 20
I had this idea in my mind, that's why I used binomial expansion
In this problem yes
why?
I tried the problem this way first and couldn't get to the answer, so I wanna know the ways
there is a way to do it with modular arithmetic.
and the other way i have in mind is a detour that uses essentially the same idea except in bulkier, harder-to-understand and more painful notation.
so like, are you a masochist?
I'm facing difficulty in these kinds of problems, so I'm learning bunch of different methods to get familiarized
when two methods are essentially the same except one is full of pain, do you still want to learn the painful one?
(-3)^4 = 81 = 1 mod 20, therefore (-3)^101 = (-3)^(101 % 4) = (-3)^1 mod 20
I love this
like what could you do here? break off one (-3) and then go with (-3)^100 = 81^25 and then binomial-expand AGAIN and have to face twenty-five vanishing terms AGAIN?
it's a waste of effort.
Wow, this is nice
Understood

I will try more problems and get back here if I have any doubts

"For what values of p the integral converges?"
My idea was to do evaluations at the 0 and inf
But I think I didnt exactly do them right
At 0 i said it behaves as 1/sqrt(x)^p

can someone help me with this question
what is the question?
the first one
show that an equation is the derivative of another
pls create new channel
how
this channel is have a question
find a closed channel and reopen it by using .reopen
im confused
i am trying to find out how to move from one equation to aother
@dry tartan do you know how to do diffrentation?
im just starting to learn it, so im a little confused
do you know the power rule?
part a is:
no
As a helper, please do not give out answers that could be copied as a homework solution. Have the student work through the problem themselves and guide them along the way.
g (x) = x^2 - 5x
yes
and g '(x) = 2x - 5
yeah
im not sure how to "show" that the second equation is a derivative of the first
To calculate the derivative of the function
g(x) we use the formula to calculate the derivative of the quadratic function as follows:
d/dx x^2 = 2x
so, d/dx g(x) = d/dx (x^2 - 5x)
= d/dx x^2 - d/dx 5x
= 2x-5
yes
so the derivative of g(x) = x^2 - 5 is 2 x - 5
typo
can we move on to the next part of the question pls
wait lemme move it down here again
sure
yes
so, what does “derivative” mean
so the derivative of g(x) = x^2 - 5x is 2 x - 5
is it a line
no its a curve right
and the tangent is a line going in the direction of the line
yes
on a specific point
wait i will solve for part b
for example g’(7) gives the slope of tangent to g(7)
i see
so now your question wants the slope
your “slope-outputting-function” is 2x-5
so lets start with the first one aka 1
so 2x-5 outputs the slope, which is 1, aka 2x-5=1
oh
is that clear or is it weird
so 2x-5 is the gradient
and the question gives me a set of gradients
and i assume i solve for x?
but what about the y coordinate?
the question wants both x and y
so you have to subsitutte the x back into the original function
so i put the x back
to find y
yea
yep
alright then
ill do that later
so the last one is just sketching right?
so i find the x and y coordinate of all 5 gradients and then plot them on a graph?
yeah
alright then
looks like that question is done
ill go do it now, thanks
wait a minute
@ornate leaf i have one question
in a
in the first equation its -5x
and in the second one its just -5
what happened to the x?
solution of part b(i think so):
To find the coordinates of points whose tangent slope is m, we need to use the formula for tangent to a curve at a point.
The formula for tangent to a curve =f(x) at point P=(x0,y0) is:
y - y0 = f'(x0)(x-x0)
So, to find the coordinates of the points whose tangent slope is m, we need to solve the following equation to find the values of x respectively:
f'(x) = m
For the function f(x) = x^2 - 5x, we calculate the derivative of f(x) as follows:
f'(x) = d/dx(x^2 - 5x) = 2x - 5. as mentioned above
So, to find the coordinates of the points on the graph of the function
f(x) has a tangent with slope equal to m, we need to solve the following equation:
2x - 5 = m
--> x = (m+5) / 2
After finding the value of
x, we can calculate the corresponding y value by feeding the value of x into the function
f(x), ie:
y = f((m+5)/2) = (m+5 / 2)^2 - 5(m+5)^2)
So, the coordinates of the points on the graph of the function f(x)=x^2−5x whose tangent has a slope equal to
m is:
((m+5 / 2) , ((m+5)/2)^2 - 5(m+5 / 2))
bruh so tired
@dry tartan
i see
the power rule
yes, in diffrentiaiotn, whenever you see constant*x, just change it to c in the thing
and whenever you see just a constant by itself, you can ignore it
alright
okay, i helped u part a and b. can u do part c?
yes
it is just graphing and drawing the tangents
ok i have another question
slightly different

l
what u mean
oh sry
pls help
divide 25 by 4 and multiply the result by 9
do the same thing, you have to know what they multiplied 12 to get 78
(just divide 78 by 12)
i think ur just getting epople to help with ur homework and not understanding it
OK
LETS DO THE SAME THING U DID HERE
what did u do??/
thanks for you help i got it now 😛
AYYYYYYYYYYYYYYYYYYYYYYYYYYYY
the shorter one will be the smaller number
ok
so basically
u divide 4 by 1.6 and that gives u 2.5
to understand more 1.6 multipled by 2.5 gives u 4
yeah
WAIT
no...
Divide 1.6 with 4
4 / 5 = 1.6 / x
it won't be a decimal answer
no

yes
yea

im dont quite understand someting, when subtracting u need to have a cd and i got which is 20 and thenm your supposed to times the numertor by how much it took you to get the that number (the denominator) so i dont understand here which number i should times by numerator by? if that makes sense
u need to have a cd and i got which is 20
Yes the denominator needs to be 20, so start with 3/4 fraction, 4 times what equals 20?
5
supposed to times the numertor by how much it took you to get the that number (the denominator)
So if you multiplied by 5 in the denominator then you need to multiply the numerator by that same number
both the numerators or just one?
For 3/4 to have a denominator of 20. you need to multiply by 5
For 1/5, would you multiply the denominator by 5?
no that would make 25
So then what should you multiply by to get 20?
4
From there, do you know what to do?
yep, but i was wondering can you use different numbers to muliply the numerators?
like obv the number you got to get to 20 but like it two different numbers 4 & 5 i though you had to use only one of them
Do you mean if the common denominator was 20 and take the 3/4 fraction, you multiplied the denominator by 5 and the numerator by a different number that’s not 5?
i meant like for both fractions dont you use the same number like either 4 or 5 or do you use 1 number for that fraction like 3/4 you times the numerator by 5 and the other fraction numerator by 4?
No you don’t use the same number for both fractions. You use whatever number that gets you that common denominator
oh okay that makes a lot more sense because i watched a youtube vidoe on it and it didnt tell me that
thank you
As before for 3/4, the common denominator is 20 so you multiply by 5. The other fraction 1/5, you don’t multiply by 5 to get a common denominator of 20, do you?
You need to apply a different number
4?
Yes
ah okay i understand now
Notice how you had to apply two different numbers for each fraction
yep i see it now
thank you very much i have a test exam in just a while

For which $\beta > 0$ do you guys think this function is continuous?
$$
g: \mathbb{R}^2 \rightarrow \mathbb{R}, \quad g(x,y) = \begin{cases} \frac{x^4-y^4}{x^4+y^4}, & \text{ if } (x,y) \neq (0,0) \
\beta & \text{ if } (x,y) = (0,0) \end{cases}\text{?}

like the areas of the shapes cut off
if i have a triangle with it's corners both touching the surface of a circle part of the triangle is cut off, i need to find that area so i can subtract it from the actual area

I am trying to get the polynomial differentiation rule by pullbacks or differentials of
that tensor field. But I am not sure what to do. So we can write x^n as e tensor e n times
e being the standard basis for R* I am trying to then get the polynomial rule
I know this is kind of stupid, but I am trying to
understand tensors a bit better What doesn't make sense to me is then, if we
take the exterior derivative of this form, we get
an n+1 form. Which doesn't really make sense.
Unless I am wrong
I forgot to add a part
I am trying to get nx^n-1 as some sort of thing from treating x^n as an nth rank tensor
so I know that x^n can be represented as
e tensor e n times I think. Where e is the standard basis for R*
So like. We have a tensor field being dx tensor dx n times in local coordinates right?
is what I am saying impossible/ doesn't make any sense

My answer is the red lines. My answer gave me 3/4 marks, which means I missed something out or I got something wrong, what is it?
its a maths website for homework, if its correct a bug maybe?
<@&286206848099549185> Is there a reason I got 3/4 marks or is the website tripping

soo liek
23rd question please
Oh my bad
You didn't need to close your channel and open a new one
i closed mine'
i think
yea it is
You didn't need to close your channel and open a new one
You did not need to close it
Anyways, what's your question?
so like
when i was doing the adding part
would it be 1.331 + 64.2
also why are the (1.1) and (1.2) in brackets
Where is this coming from?
I know that, I mean how did you get that value?
this
but then
d exponent 3
1.1 x 1.1 x 1.1 = 1.333
and the
5 + f e
57 + 1,2 = 58.2
ohhh
so it would be 5 x f then e
5 x f and the total
- by e
5 x 1.2 = 6 x 57 = 342
342 + 1.3 = 343.3
is that right?
@wary stream
Don't ping me
mb
Decimal part is wrong
Where is .2 coming from?
342 + 1.3 = 343.2
How did you get .2? When the decimal was .3
Yes
Why would you do the d^3 again?
You already did it
yeah
okay
5 x d3
d3 = 1.1
d = 1.1
1.331
5 x 1.3 = 6.5
6.5 x 57
370.5 - 343.3
27.2
is that right
27.2 - 1.2
=
26

@hallow dock Has your question been resolved?
<@&286206848099549185>
They are using a lot of "law of total probability", where one term reflects if the defendant is innocent, and the other term reflects if the defendant is guilty
For example, let's say:
- The defendant is guilty (0.8)
- Judge 3 votes guilty (0.8)
- Judge 1 votes inno (0.2)
- Judge 2 votes inno (0.2)
Multiply those together, you get the first term of the numerator
@hallow dock
The other term of the numerator is the same logical process, but if the defendant is inno

The height of rectangle ?
yea
prolly a better letter, like a
so u are given the y vvalue is a, then find the x value using the parabola equation
u can calculate the value of Q and P
using the height
the y value of P is a, so u can calculate the value of x
But height is only a variable no?
in terms of a
yea, but the points Q and P pass through the parabola, so u can plug it in
So like P=6-x^2?
$a=6-x^2$ where x is the x value of Q and P
yes
Okay
tan g ent
u can let the x value of P be a instead of height, so instead of sqrt it is a square
so u have $y=6-a^2$ where y is the y value of Q and P
tan g ent
so u have that the length is 2a, and the height is 6-a^2
now u find pereimeter in terms of a, and then maximize

What are the zeros?
ok
@digital relic Has your question been resolved?
The ``zeroes" of a function are the points at which the function crosses the x-axis. So this is when $y$ or $f(x)$ is equal to zero, hence: $f(x)=2(x+4)^2-8=0$. Once we know this we can solve for the $x$-values of our zeroes. From there the coordinates can be found, do you think you can do that?

This still confuses me. So I have 2x+2y but I don’t understand the maximising part
y and x are related, right?
i mean you can't choose x and y freely
they have to satisfy y = 6 - x^2
that’s the equation of the parabola correct
Oh yeah
Ah okay
Pretty sure it should be
4x + 2y
Why would it be 4x
But I asked this question before as well and 3 people said it would be 2x+2y or whatever variable 2a+2y etc
I can see it being 2x+2y but I don’t get how it would be 4x+2y
One sec
good catch
