Chain rule

I'm BEGGING

Begging what lol

For them to use their neurons

#

They need to

steep lance Oct 25, 2024, 2:30 AM

Agreed

Wasting 2 hours on a simple derivative is wild

fluid bough Wasting 2 hours on a simple derivative is wild

Any more than 10 minutes is wild enough

#

You do multivariable cal?

steep lance Oct 25, 2024, 2:32 AM

#

I don't think so.

#

I do know basics of vectors

#

But no complicated integrals

fluid bough Oct 25, 2024, 2:33 AM

#

It's like find the gradient of w=(x^2)-2zy+yz^x

#

You just take a partial differencial of each variable to find the gradient

steep lance Oct 25, 2024, 2:33 AM

#

I'd be able to partially derive it, without proper logic though

#

I've not theoritically covered multivariable

fluid bough Oct 25, 2024, 2:34 AM

#

Fair enough

fluid bough Chain rule

okay got it

fluid bough Oct 25, 2024, 3:07 AM

#

Good person

half pelican Oct 25, 2024, 3:08 AM

#

is the answer b?

fluid bough Oct 25, 2024, 3:18 AM

#

Do you know how to confirm your answer?

half pelican Oct 25, 2024, 3:22 AM

#

yea sure

#

so I used the chain rule where u' (x) is found using the quotient rule

#

and then i got 7x^e/x^6+9

#

then u'(x) = (7e multiplied by x^e-1)

#

x^6+9

#

subtracted by (7x^e)(6x^5)/(x^6+9)^2

#

and then i simplified everything

#

and it gave me the answer that matches option b

#

so it should be that correct?

fluid bough Oct 25, 2024, 3:26 AM

#

Yup

#

If you're sure it matches up

#

You can calculate everything

#

You just don't know the steps in order to do so

half pelican Oct 25, 2024, 3:27 AM

#

can you please confirm thats the right answer with me?

#

i dont want to get the question wrong or anything

#

im like 90% sure thats the right answer but who knows

#

i could be wrong

fluid bough Oct 25, 2024, 3:33 AM

#

Sure

#

Give me a sec

half pelican Oct 25, 2024, 3:34 AM

#

yea no problem, take your time

fluid bough Oct 25, 2024, 3:53 AM

#

I'd say you're good

half pelican Oct 25, 2024, 3:57 AM

#

I got it wrong

#

shoot

#

i have one more attempt to get it right

fluid bough Oct 25, 2024, 4:05 AM

#

It's either F or the last one

#

I'd say F though

#

Waitactually

#

Giveme asecond

half pelican Oct 25, 2024, 4:07 AM

#

okay sounds good, i really want to get the questionr right

#

thank you

fluid bough Oct 25, 2024, 4:11 AM

#

I got E

#

You can check

#

I computed the d/dx of it

#

And it was the closed

#

closest

#

It's the reason I picked the wrong answer before

#

#

I was differentiating at 2

#

And it is partially discontinued at that point

half pelican Oct 25, 2024, 4:18 AM

#

E okay

fluid bough Oct 25, 2024, 4:18 AM

#

If it's wrong I am quiting life

half pelican Oct 25, 2024, 4:18 AM

#

no youre good lol

#

its fine

#

ill just double check with uday

#

@steep lance

#

is the answer e?

half pelican Oct 25, 2024, 4:19 AM

#

fluid bough If it's wrong I am quiting life

i mean it has to be E if it wasnt B

fluid bough Oct 25, 2024, 4:20 AM

#

Ye

#

I graphed all the others with the derivative and they didn't match

#

Just double check
