Calculate the area between curves y=e^x and y=-e^x on the interval [0,1]

Answer 1

what's the problem? e^x is about the simplest thing to integrate

integral[0,1] e^x - (-e^x) dx
= 2e^x [0,1]
= 2(e-1)

Answer 2

that is how I worked it out as well but I did not know if it was that simple I find ways of making simple things hard sometimes thanks for the help
