To remove that front e^x let which gives (I have subbed in for )
Then carry on with your trig sub
i'm currently trying to integrate....
e^(x)*sqrt(1-e^2x)
i used x = sin(theta)....
i'm just unsure what to do about the left side of the equation,i understand cos(theta) takes the place of...sqrt(1-e^2x)..but how/what takes the place of e^(x) is it just sin(theta)? -thx
e^(x)*sqrt(1-e^2x)
