Hi thanks for the help lately its been good. I don't post these unless a day goes by without a solution.
(int) 2 sqrt(1- e^(-x)) (e^-x) dx
u = 1 - e^(-x)
du = - e^(-x)
General power form:
[1 - e^(-x)]^(3/2) / (3/2) + C
4/3 [1 - e^(-x)]^(3/2) + C
however here is the ti-89 answer:
somehow something has been added in the nominator.
how did I go wrong? Thanks!
