Question

can someone help me out with this problem

Answer 1

\[\int\limits e^{\sin(x)}\cot(x) dx\]

Answer 2

u-substitution with sin(x)... ?

Answer 3

I think this might be integration by part cyclic problem

Answer 4

Yup definitely U substitution

Answer 5

the derivative of sin(x) -> cos(x)

Answer 6

I am not sure that will help though, that doesn't work

Answer 7

so you will get

\[\int\limits {e^u \over u }du\]

I am not sure what to do next

Answer 8

Integration by parts

Answer 9

oh, uv - dvu

Answer 10

ouch beyond my abilities right now, thats calculus 2

Answer 11

oh right

let w = e^u then dw = e^udu

and 1/u du = dv then ln|u| = v!

Answer 12

hmm... but I get stuck with

\[\int\limits \ln(u) e^u du\]

Answer 13

Hold on, I am working this out

Answer 14

what class is it for?

Answer 15

mulitvariable calc

Answer 16

I think you have to use exponential integral, I don't know much about that

Answer 17

hm

Answer 18

well, I just wanted to throw in something interesting

Answer 19

:)
