The same fucking way my student fucked up this simple proof.

>> No.7082862

>>7082859
It's a single variable function first of all, so it's graphable.

Then you just need to understand the Fundamental Theorem of Calculus, and reparametrization of functions.

You gonna post this picture of your incompetence now everywhere?

Into the trash it goes.

>>7082859

You don't. You compute the problems than get you engineering degree like everyone else on /sci/

>> No.7082878

>>7082872
Exactly, why would he write something like that?

>>7082870
>incompetence.

I TOLD HIM SPECIFICALLY TO SOLVE IT A CERTAIN WAY. IM NOT TELLING HIM HE IS WRONG, BUT HE DIDNT DO WHAT I SAID

That feel when he posts on /sci/ and is now depressed because you hate him.

Community College. Yes, I am retarded.

I might be being retarded, but where does your 2dx come from on the second line?

Should it not be dx/2?

>> No.7082984

>>7082980
* just dx

You again? Get the fuck out of here, you're already a confirmed faggot.
You made a thread to garner support. Out of 43 posters, you had like, 5 people agree with you. Shut the fuck up with this bullshit, we're sick of it. Unless...you're trying to get people to shit on you?

you don't visualize such integrals...
you just do them

Nah, it's cheaper. I'm doing it too.

u = 2x

du/dx = 2

du = 2dx

>> No.7083699

>>7082860
so what did you want him to specifically do?

>> No.7083703

>>7083699
I wanted him to break the left side into a more complex version. Doing it harder will make things easier for them. If they can grasp turning simplicity into complexity, they can turn complexity into simplicity.

>> No.7083711

>>7083703
so he would of had if he did not screw up step 1 in the crossed-out work. Second term should of been 1/cos^2

Why is this wrong?

>> No.7084185

>>7084174
because the derivative of <span class="math"> f = g(x)^h(x) [/spoiler] isn't <span class="math"> f' = h g^(h-1) * g' h' [/spoiler]
it's only true for a constant <span class="math"> h(x) [/spoiler]

Try
ln(f) = ln(ln(x)^tan x)
ln(f) = tan x *ln(ln(x))
f= exp(tan x*ln(ln(x)))

>> No.7084197

>>7084185
And then apply the product rule on the exponent and multiply the result with the original expression exp(tan x*ln(ln(x))) ?

Like this?
( 1/cos^2(x) * ln(ln(x)) + tanx * 1/lnx *1/x ) * exp(tan x*ln(ln(x)))

Take your own advice you cunt, why are you even posting this again?
