Integral ((e^x)*(1-(e^2x))^1/2 dx
How can I solve this one. I don't know how to start it.
I suggest you combine the terms and then take as a common factor and take it out. Then use a substitution that will get rid of the outside, and use another (trigonometric) substitution to solve. This way isn't pretty and I'm trying to find another easier way.
EDIT: @Jhevon: he did pepper it with parentheses, so I don't think there is an ambiguity here: the is in the square root.
EDIT2: See ya!
