for the debates I did, if someone pointed out a fact or statistic, you generally accepted it as true unless it was obviously false or wild, since it wasn't worth the effort to try and crack down on their statistics than it was cracking down on their argument

#

I used a study from like 1992 once and got away with it lol

#

Influencing people and trying to reach an agreement with them is a far cry from formal debates

#

I don't think I have ever participated in a formal debate

“You are obese because you’re 6 ft 1 and 290 pounds!”

yeah that's fair

#

But I'd like to think I am pretty good at getting people to agree on things, as it is a core requirement in my line of work

#

Different groups have different interests, and everything has a pro and con

#

So how do you get them all to agree on a course of action?

tardy rain
#

If you're too stuck on the facts, your opponents might think you're being rude, insulting, etc

quasi blaze

#

Just dont focus on the facts

#

Youre attacking their argument

low chasm
#

I think you're overemphasizing the "debate" part of this, if you're just discussing some points that you disagree with someone on, getting caught up in the semantics of stuff isn't super worthwhile

tardy rain
#

They're obese - fact
Obese people are at a higher risk of diabetes, heart attack, stroke, etc

#

They lack quality of life, their life is more expensive

They could improve their life by going to the gym, eating better

Its not just "youre fat, listen to me"

If all you have is "youre fat, so youre wrong" then youre not doing much debating

Also calling someone obese sounds like an insult

Are you sure youre not being fallacious yourself?

If I am trying to convince someone that we need to upgrade a system, I won't state facts that don't support it for example

#

As always, context matters

#

And I really don't think I have ever framed something as a formal debate when trying to argue for a certain position on things (professionally and personally)

#

what kind of argument are we talking? misleading statistics or something ?

why are we talking about obese

the answer would depend, then. A formal debate typically has a set of rules for what is and isn't appropriate

honest star

Ok

honest star
# quasi blaze Both

If it's a discussion, the point isn't to "win", but to come to some sort of mutual understanding of both sides. So I would typically say that their tone isn't helping them convey their actual point.

#

So if someone is saying factually correct stuff but being a dick about it, I'd say something like "I might agree with you, but you're coming across really poorly. So it's less clear what your position actually is. Do you mean X?" where X is restating their point in a less dick-ish way

I just had a vim pimping idea. I like my blue colour scheme, but a lot of my colleagues scream when I show it. Sometimes that's the goal, but sometimes I just want to show them something interesting in the code. I should add a keybind to change the colour scheme to something that's easier for people to read in case I want to present something. Typing :colo default takes too long time.

On the point of "it's not just about what you say, but also how you say it", because I'm in a chatting-avoiding-work-kind-of-mood... If you do find someone is being a dick, I think it's more productive to focus on how they can communicate their message better rather than being like "you're being a dick". Even the framing for how you approach feedback can really change how a person receives it.

How you convey your point matters, and if you are trying to address it you need to tell the other person something along the lines of

People just communicate differently. There are lots of variables involved in that.

it's not a logical fallacy though, is it?

Logical fallacy of the afternoon: Appeal to Authority

The appeal to authority fallacy is the logical fallacy of saying a claim is true simply because an authority figure made it.

"This skincare product must be the best because a famous actor endorses it."

oh

#

okay

#

here @quasi rose

#

This is actually really insightful.

#

If you need more explaination, ping me

#

yes?

#

that is amazing!

#

would you mind solving a question

#

regarding quadratic equations?

#

okayy

#

let me get one

#

got one

#

Find the set of values of a, for which (a - 1)x² - (a + 1)x + a + 1 > 0, for all x∈R, where R is the set of real numbers.

#

Is it too hard?

#

Should I give you an easier one

#

Okay!

#

Are you gonna do it?

#

great!

#

that's okay, it took me about 5 minutes to solve it too (I should be taking 2 minutes)

#

I actually don't know because I haven't solved it yet.

#

Lemme solve it quickly

#

I did solve it, but I lost the solution

#

and only the question remains

#

Thx

#

Wht abt this one?

#

How?

#

What?

#

Waha

#

Damn

#

Yeah

#

Gg

#

Haha

meager stratus
#

Heyy sorry my power went off

#

I got a > 1

#

how did you solve it?

#

that should give you a ∈ (-∞, -0.4) ∪ (0, ∞)

#

wait a second

#

larger than zero?

#

a discriminant larger than zero would mean it has two distinct roots

#

in this case,

#

we want the quadratic to always be positive

#

we want no roots

#

we must take the discriminant to be less than 0

#

also

#

for the quadratic to be positive

#

you also set the first term (a - 1) to be greater than 0

#

a belongs to the interval which includes (-infinity to -0.4, but does not include -0.4) union with (0 to infinity, but does not include 0)

#

ah yes why not

#

Let for a ≠ a₁ , f(x) = ax² + bx + c, g(x) = a₁x² + b₁x + c₁ and p(x) = f(x) - g(x), and p(x) = 0,
ONLY for x = -1, and p(-2) = 2. Then calculate the value of p(4).

#

@quasi rose

#

This one appeared in a competitive exam.

#

Okay I solved it

#

Were you able to solve it?

#

yes.

#

But no other value of x will produce 0

#

other than -1

#

that is important.

#

wait what

#

why are you dealing with discriminants?

#

Quadratic Equations might seem like an easy topic, But there are several challenging parts in it.

#

The correct answer is 50.

#

(knockout, moribund, injured, hazard, concept, structure, magical, mental, companion for the mod names)

meager stratus
#

Now I will begin the solution.

undone thorn
meager stratus
#

Anyways.

humble anchor
meager stratus
#

p(x) is defined as f(x) - g(x)

humble anchor
#

lol i just saw this channel first and thought yall were done, headed off anywho

meager stratus
#

subtracting two quadratic equations.

#

and p(x) must also have two roots

#

but both the roots are -1

#

hence f(x) and g(x) must have common root -1

meager stratus
#

Remember we can write a quadratic equation as a(x - p)(x -q)

#

when we subtract f(x) and g(x)

#

the a term becomes

#

(a - a₁) (x + 1)²

#

to find the value of (a - a₁)

#

Substitute x for -2 in p(x)

#

and we get (a - a₁) = 2

#

hence p(4) = (a - a₁) (x + 1)² = 2 (4 + 1)²

pliant nexus
#

wth is happening here 💀

meager stratus
#

hence p(4) = 2(5)²

p(4) = 2 × 25

#

hence p(4) = 50

#

Did you get it @quasi rose

meager stratus
pliant nexus
gritty zinc
# meager stratus hence f(x) and g(x) must have common root -1

this part isn't really important, I think. p(x)'s quadratic coefficient is a-a₁, and so since a≠a₁, it must be a quadratic polynomial. if it only has one root, then it must be that p(x) = A (x+1)^2. then from p(-2)=2 we get A=2, and hence p(4) = 50.

meager stratus
#

It is the converse of a fact.

#

Proving it requires like 2 pages.

#

Not 2 pages

#

but like

#

maybe 1 page

#

it's long

#

and yes it isn't really important for this, but it should be acknowledged

#

Do you want one more question

#

Here is another.

#

If p and q are two real numbers satisfying 2p² - 3p - 1 = 0 and q² + 3q - 2 = 0, find the value of (pq + p + 1) / q

#

@quasi rose

#

Wait I'll edit the question

#

Done

gritty zinc
meager stratus
#

yes.

#

If I did not make any mistakes while writing the question down.

#

oh frick

#

there is a mistake

#

@gritty zinc @quasi rose

gritty zinc
#

yeah, as written there's 3 possibilities.

meager stratus
#

Wait a second

#

No there aren't any mistakes

#

I judged myself wrong.

#

My original question was correct.

#

My friend's notes.

#

He is studying for an Indian exam

#

Called Joint Entrance Exam

#

Apparently these are trivial questions for 17-18 year olds

#

💀

pliant nexus
#

i'm from india too

gritty zinc
meager stratus
#

1 being the correct answer.

#

How exactly do you land on 4 options?

gritty zinc
gritty zinc
jaunty wraith
meager stratus
#

Well if you look at them carefully.

#

They are similar.

#

Divide the second quadratic by q² and multiply by -1.

#

And then both quadratics are similar.

gritty zinc
#

i mean, they are, but I don't see how this makes 1 the "correct" answer?

meager stratus
#

Which means that the roots are p and 1/q

#

then using product of roots and sum of roots

#

we find out that (pq + p + 1) / q is 1.

gritty zinc
meager stratus
#

But I think your point holds

#

Well never mind.

#

I'll let my friend know about the extra answers.

#

Well can you do this one?

#

This one also has triangles in it.

granite tree
#

How would you set them equal to each other? That seems like the crazy route

#

Oh, I dunno; keep it simple. Two quadratics, and we know how to get the roots of a quadratic equation, so why think harder

#

Hi

granite tree
#

Thats why algebra mastery is so important for college math success: not being afraid of some algebra

meager stratus
#

I think that's enough for today.

#

I'm going to sleep

#

It's okay

granite tree
#

Also, this stuff becomes a little more intuitive after linear algebra, you'll see the patterns in which you can solve a system of linear equations

strange blade
#

quadratics stuff is like Grade 9 thing in Australia

#

So yeah, it would be quite trivial for a 17-18 year old

#

No

#

We have ATAR exams instead.

#

I guess it's sorta comparable to A levels

#

our maths homework in 8th grade is solving for some simple quadratics

#

but since we are in the "extension" class, we get harder problems

granite tree
#

It's a University course. Algebra mastery is hard; a lot of Uni students start thinking they have good fundamentals and struggle with Uni math. So, take algebra serious and practice. It'll help you for a long time.

what does it even stand for?

strange blade
# solemn tulip what does it even stand for?

The word surd comes from the Latin word surdus, meaning deaf or mute. In the early days of mathematics, Arabians used to consider irrational numbers as mute. This means there was no value in these irrational numbers. Only rational numbers were considered audible.

young shoal

that's usually called a radical

this is the first time in my life I've heard of a "surd"
