>33.34%

Shouldn't it be 25%?

Math post-doc here. WTF is this shit? I can do quantum cohomologies, complex functional geometry and algebraic number theoretical analysis. But triple integrals? No way! That's way above my level. There's like 3 experts on triple integrals in the entire world and it's highly unlikely one of them browses 4chan.

So sci, why aren't you majoring in chemical engineering?

Can I get some help on this problem? I'm having a ton of issues with reducible equations in DFQ...

ydx+(1+ye^x)dy=0

Here's what I tried:
u=y
du/dx=dy/dx
y+(1+ye^x)dy/dx=-
u+(1+ue^x)du/dx=0
Nope.avi

Correct answer is ylny+cy=e^-x


just solve it by using an appropriate substitution.
>FYI, this isn't homework, I'm just trying to study.

I've got a final exam coming up soon and I have no idea how to do this problem. Can /sci/ help?

Find the minimum value of the function f(x,y,z)=x^2+y+z along a straight line which contains the points (2,3,4) and (1,6,8).

Let me know how to do it please, don't just post the answer!
