1. The problem statement, all variables and given/known data Area between curves y=((e^x)-(e^-x))/2 and y=2e^-x for -1 < x < 2 2. Relevant equations I know the formula is the integral of ( u(x)-l(x) )dx, but I'm having a lot of trouble trying to integrate this. integral from -1 to ln(5)/2: (((2e^-x)-((e^x)-(e^-x))/2))dx + int. ln(5)/2 to 2: (((e^x)-(e^-x))/2-2e^-x)dx 3. The attempt at a solution I graphed everything and solved for x (intersection at x=ln(5)/2) but have been unable to get the right answer after that point. I tried splitting the formula into smaller integrals by linearity to simplify integration but consistently got the wrong answer for that. Should I try to split it up again? Or am I missing a pretty easy integration in here?
