Question

Just want to make sure I can do this

Got the integral of e^x * e^x dx.
I make u=e^x, and du has to be e^x as well. So I just use one for each, and end up with integral of u du.

Answer 1

\[\int\limits e^x e^x dx\]

Answer 2

?

Answer 3

\[\int\limits\limits e^x e^x dx = \int\limits e^{2x} dx\]

Answer 4

u = 2x yadi yadi yada

Answer 5

or sub \(u = e^x\)

Answer 6

oh @DurableToaster has written that already oops

Answer 7

yeah

Answer 8

why not?

Answer 9

i dont talk to kids with cp

Answer 10

hey I don't have CP
just chicken pox

Answer 11

but yes, not talking to people with CP is the way to go

Answer 12

thanks

Answer 13

That's strange. Couldn't I just take the whole e^x as u? Cause d/dx e^x is e^x, u=du, so I could substitute the e^xs for different things, getting e^x^2 * 1/2.... The Same as you got. Sweet!

Answer 14

Yes you can
