1. The problem statement, all variables and given/known data Let F(b) be the exact area under the graph of y = x2*e-x between x=0 and x=b for b>0. Find the formula for F(b). 2. Relevant equations int(uv')= uv - int(vdu) 3. The attempt at a solution u = x2 and dv = e-x, thus u'=2xdx and v=-e-x. y= -x2*e-x - -2*integral(xe-x). = -x2*e-x -2xe-x-2e-x. This does not yield the correct equation, so where did i make a mistake?
