I'm supposed to find several indefinite integrals, but I am not sure exactly how to do each, especially as they involve natural logs and trigonmetric functions.
The three are:
dx
((e^t^x) cos (e^t))/(3+5 sin (e^t))
and lastly
for the frist one
Let
For number 2 you have both x's and t's but no dx or dt what variable are integrating with respect to?
For the last one
let

Good luck.
Hello, Pikeman85!
These all require "simple" substitutions.
. . The trick is to recognize them.
We have: .
Let
Substitute: . . . . etc.
Let
Substitute: . . . . etc.
The denominator is: .
The integral becomes: . .
Substitute: . . . . etc.
Edit: I'm way too slow this time . . . *sigh*
