1, 2, 4, 7, 9 are simplifyy and others are prove

What would the correct simplification of the 1.st one be?

Are these both right for the 1st one?

[haughty grove]

Umm translate ig?

[haughty grove]

Sec²x

[dark basin]

1, 2, 4, 7, 9 are simplify and others are to prove

[haughty grove]

Oh ok

[haughty grove]

1st

[dark basin]

Yeah that's what gpt told me, but I haven't learnt sec thing yet

[haughty grove]

WOAH REALLY?

THAT CANNOT HAPPEN?

Bro what

[dark basin]

Bruh

[haughty grove]

Lmfao

Aura debt bro

For lifetime

[dark basin]

Yeah

[haughty grove]

Try 2nd

What is tanx?

Remember

Aura debt🥀

Put the fries in the bag bro

[haughty grove]

Nevermind

Then tan²x+1 is the answer for u

Let's try second one

[dark basin]

Bro

[haughty grove]

🙏🏻.

[dark basin]

Hold on roryfan

[haughty grove]

What is tanx? @dark basin

[dark basin]

But gpt told me 1/cos2x

[haughty grove]

In terms of sin and cos?

[haughty grove]

Uhm no?

[haughty grove]

Yes,

The tan thing

For 2nd one

You have to rewrite tanx= sinx/cosx

And it's self evident that tan²x=sin²x/ cos²x

Get your notebook

And try solving it further

[haughty grove]

It's cos²x

[real horizon]

That is correct

[haughty grove]

Cos2x is diff

[real horizon]

Use ^

[haughty grove]

...

[dark basin]

I got = 1 + 2tan2x for the second one

[haughty grove]

Plz use ^

For powers

[real horizon]

Bro

[dark basin]

1+2tan^2x

[haughty grove]

bingooooo

Correct

[haughty grove]

Now let's get to the third one

Do you know wha cot is?

@dark basin

[dark basin]

Wait before I move on, so these are the correct simplifications for 1st and 2nd?

[real horizon]

3rd one not even true

🥀

[dark basin]

Tf? 😨

Really?

[real horizon]

Yeah

/- works tho

Instead of +

[dark basin]

I'll just skip that for now then

[dark basin]

But are these correct yeah?

[real horizon]

Yeah

[dark basin]

But 4th one

[haughty grove]

What is the second solution.

I don't understand

[dark basin]

1 + 2tan^2x

[haughty grove]

My solution for this problem is like this:

Tan²x=sin²x/cos²x

And add

Sin²x+1/cos²x

1=sin²x+cos²x

2sin²x+cos²x/ cos²x

Divide the term cos²x into both numerators

2tan²x + 1

[dark basin]

Yeah that's what I got

[haughty grove]

The solution I mean

Not the answer

[haughty grove]

Oh yes

That's another approach

[dark basin]

Yeah that was in my book

[haughty grove]

1/cos²x = sec²x = tan²x+1

[haughty grove]

You just have heard about secant?

Don't you?

[dark basin]

Haven't learnt it yet

[haughty grove]

You might call it SMTH else

[dark basin]

I've only learnt sin, con, cos and cot

[haughty grove]

con?

[dark basin]

Or that's what they have showed us

[real horizon]

?

[haughty grove]

Tan?

[real horizon]

Tan?

[dark basin]

Wat

[haughty grove]

Haven't learned tan?

[dark basin]

Sin, cos, cot and tan

[real horizon]

What is con?

[haughty grove]

And what's con?

[dark basin]

These I've learnt

[real horizon]

Yeah tan

Not con

[dark basin]

No con, mistake

[haughty grove]

No csc and sec?

Okay let me teach now

[dark basin]

Nope

[haughty grove]

Simply cscx= 1/sinx

[real horizon]

It’s just reciprocals

[haughty grove]

And secx=1/cosx

[real horizon]

Yeah

[haughty grove]

And remember there identities

[dark basin]

It will prolly look sus if I use them here

[haughty grove]

Sin²x+cos²x=1

sec²x-tan²x=1

[haughty grove]

Bro wha

Where r u from?

[dark basin]

Estonia

I'm 10th grade

[haughty grove]

Why don't they teach csc and sec

[haughty grove]

Country with the best air quality right?

[real horizon]

Honestly

[dark basin]

Something like that yeah

[dark basin]

I think it's in 11th or 12th

[real horizon]

Why teach cot and not csc and sec bro? 😭

[haughty grove]

And csc²x-cot²x=1

[haughty grove]

BRO WHAT

WHAT

WHAT IS THIS SYSTEM

[dark basin]

Don't know

[real horizon]

And I thought our system was badly designed

[haughty grove]

Which country?

[real horizon]

India

[haughty grove]

Lol

I see

[haughty grove]

Lol true

Let's continue

[haughty grove]

Still

Weird

[haughty grove]

What is cot²x?

@dark basin

[dark basin]

Something hard

Difficult

Bro I asked for help in local group and that's the answer I got:

"Fuck math all my homies hate fractions"

[haughty grove]

Lmfao

[real horizon]

I feel you

[haughty grove]

Just stick to this server

[haughty grove]

?

Uhm

[real horizon]

Can’t ask my friends for any help academics wise

In the grp

[haughty grove]

what is cotx?

Basic definition

In terms of tan

[dark basin]

Are you testing me or you want to know for yourself?

[real horizon]

Which one you doing?

[haughty grove]

Testing you

I am not the one doing this

[dark basin]

I have no idea

[haughty grove]

I can help you to think

[dark basin]

Don't test me pls

[haughty grove]

I cannot just give out the solution

[real horizon]

??

[haughty grove]

That's against the rules

[dark basin]

4th

[haughty grove]

Okay so

[dark basin]

Simplification

[haughty grove]

cotx= 1/tanx

[real horizon]

What is 1-cos^2x?

[haughty grove]

now you know that tanx= sinx/cosx

cotx =1/(sinx/cosx)

cotx=cosx/sinx

[dark basin]

It's 1/sin^2x?

[haughty grove]

cot²x=cos²x/sin²x

[haughty grove]

Can you do it further?

Can you solve it now?

[real horizon]

No

[dark basin]

🦆

[real horizon]

Why is it in the denominator?

It’s just sin^2x

[haughty grove]

Bro the urge to go to his house and teach on paper

😭.

[dark basin]

I'm not a girl

[haughty grove]

Teaching by typing is so ass

[dark basin]

Don't simp

[real horizon]

Ayyy ong

[haughty grove]

Okay, gentleman

[haughty grove]

I am so anxious bro

Idk why

[dark basin]

Now that I said that, no one is gonna help 😭

[haughty grove]

Nope?

Never

[haughty grove]

@dark basin

Can you solve it further now?

[dark basin]

I saw rhat

[real horizon]

It happens

Fuck it we ball

[haughty grove]

Don't dodge

Just answer

[dark basin]

I don't know

My math grades this year were 3+3+3+2+2

[haughty grove]

Doesn't really matter

Forget the past

[dark basin]

I'm scared for the future

[real horizon]

Lock in

[dark basin]

Someone solved the 4th for me

[haughty grove]

Bro

We are not here to give you the solution

We are here to solve with u

And teach you along the way

[dark basin]

Let's give the answers first and later think?

[haughty grove]

That's against the rules

I am sure, you won't think about it

[dark basin]

We are beyond the rules

[haughty grove]

@real horizon what do ya say?

[dark basin]

This is actually critical

I'm gonna fail 10th if I don't submit the answers tomorrow in class

[real horizon]

**When helping people, please do not dump the full solution. **
Remember that these people are trying to learn concepts, and our goal should be to reinforce them. Giving them a solution will not help.

**Instead, give them hints and guide them toward the correct solution. **
You can ask things like "what part did you get stuck on?" or "what have you tried so far?" or give them a small starting hint. This ensures better learning. For more tips, reach out to Schlaumau (@schlaumau).

[dark basin]

This doesn't speak to me 🗣️

[haughty grove]

Okay then we take our leave

So long

[dark basin]

No

[real horizon]

5

1+tan^2x = ?

[dark basin]

Ok wait I try solve and then y'all tel me if I'm right

[haughty grove]

Blud

[haughty grove]

Yes

That's better

[dark basin]

@haughty grove

@real horizon

[haughty grove]

Wrong

[dark basin]

Wtf

[haughty grove]

Wait

[dark basin]

How

[haughty grove]

I thought that's the third one

Why'd u skip

[dark basin]

It's 4th

Agent told me 3rd can't even do

[haughty grove]

Welp in that case, correct

[dark basin]

Fuck yes

[haughty grove]

?

Do 3rd

I told u the hint

[real horizon]

No it’s wrong

[haughty grove]

.

[real horizon]

Should be -

Not +

[haughty grove]

It's correct

sin²x+1-cos²x

1-cos²x=sin²x

2sin²x

[real horizon]

No the 3rd one

Questions wrong

[dark basin]

Yeah gpt also said it's wrong

Or mistake in the text

I'll just skip it and tell the teacher tmrw

[haughty grove]

?

Is it like that

[real horizon]

This

[haughty grove]

Damn

I see

[dark basin]

I think the teacher doesn't want me to pass

But it's cool

[haughty grove]

"pass"?

This is homework

Isn't it

[dark basin]

Not really

I was put to this 3 day summer work where I need to be and then solve the homework

And that's all because my grades were so bad

So inorder to turn one grade 2 into 3, I need to do these "homeworks"

I'll move on to 5th question then

[haughty grove]

Sure

[dark basin]

How does this work

[real horizon]

Division

Since it’s in the denominator of the numerator, it goes to the denominator

[dark basin]

Explain it in kindergarten terms

[haughty grove]

Tan²x+1 = sec²x = 1/cos²x

And

(1/cos²x)/tan²x= 1/cos²xtan²x

[dark basin]

But how

[haughty grove]

Uhm

Okay so

[dark basin]

With basic numbers

[haughty grove]

$\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}} = \dfrac{ad}{bc}$

[queen plinth]

Conqueror

[haughty grove]

Hope it is clear

[dark basin]

So (1/2)/4=1/2×4?

[haughty grove]

Yes exactly

[dark basin]

I can't comprehend

[haughty grove]

Bro

[real horizon]

Multiplication is inverse of division

[haughty grove]

It's basic mathematics

[real horizon]

Think abt it

[haughty grove]

Simply

(a/b)/(c/d) = a/b ÷ c/d

Correct?

Now you inverse the second fraction

Remember

And multiply

a/b × d/c

ad/bc

Easy

[dark basin]

Og

Oh

Because of this then

[haughty grove]

Yes

[dark basin]

Gotcha

Here is my 5th then

[haughty grove]

Correct

But if you were taught csc

Then

It's csc²x

[dark basin]

https://www.taskutark.ee/trigonomeetria-valemid/

That's what we have been shown so far

[haughty grove]

Weird ahh

But wtv

Continue

[dark basin]

Now I'm done I think, no idea what's in 6th

How should I use these to solve 6th?

[haughty grove]

Ahen ahem

Here

Remember this formula:

Cos(2x) = cos²x-sin²x

[dark basin]

So this?

[haughty grove]

Use x

But whatever

[haughty grove]

NOOOOO

THAT'S A CRIME

[dark basin]

But?

[haughty grove]

Okay let me explain.

It was given 1-cos2x

[dark basin]

Yeah

[haughty grove]

Whenever putting value

Use brackets

1-(cos²x-sin²x)

Now

1-cos²x+sin²x

2sin²x

[dark basin]

I don't have this formula

[haughty grove]

Okay so

a-(b-c)

You multiply the whole term with -1

I mean

The negative sign after a

Distributes

Into all terms in brackets

[dark basin]

Yeah I understand that

[haughty grove]

b is positive so negative

-c is negative so positive

[autumn sequoia]

Unrecognized token IDENT (is) in expression

[dark basin]

How does this

[dark basin]

Turn into this

[haughty grove]

1-cos²x = sin²x

As sin²x+cos²x=1

[dark basin]

So 1-sin^2x is cos^2x

[haughty grove]

Yes

[dark basin]

So 6th is done

Wait

But something is wrong no?

How can 1+cos^2x-sin^2x be 2cos^2x

[haughty grove]

BINGO

[dark basin]

Or it's 1+ but the -sin^2x turns it into 1-sin^2x?

[haughty grove]

Rearrange

1-sin²x+cos²x

cos²x+cos²x

2cos²x

[haughty grove]

We don't take the right sign

We always take the left one

[dark basin]

But it won't work without re arranging?

[haughty grove]

There are many approaches

Lik writing 1+cos²x = 1+1/sec²x

But leave it

Rearrange

Best thing

[dark basin]

But this worked tho no?

[haughty grove]

Yes

True

But 1+ is wrong notation

You take the left sign

[dark basin]

So the 1 is alone and it's +cos^2x

[haughty grove]

Yes

[dark basin]

Gotcha

I'm trying to do this without gpt

Is it correct so far?

Will the final simplification just be sinx/cosx?

Or just tanx

[haughty grove]

Bye gng

It's late now

For me

<@&1283689826742440016> help her plz
