I've got a final tomorrow and ive been working my butt of studying for it, but I've run into a snag.
It has to do with e's, and Ive forgotten it from high school calc classes
I know the int of e^x = e^x but.....
The int of e^(x^2) dx = (e^(x^2))/2x + C correct???
You set u=x^2 du=2x dx THEN du/2x = dx
Is that right??
The same goes for int of e^(2x) = (e^(2x)/2) + C
and
int of e^(x/2) = 2e^(x/2) + C ?????
Please Help!
P.S. What is the derivitive to the first one??
