1. The problem statement, all variables and given/known data Evaluate the definite integral: 2. Relevant equations [tex]\int u^n du/dx[/tex] = u^(n+1)/(n+1) (n not equal to -1) 3. The attempt at a solution (-1) muliplied by [tex]\int[/tex] (e^-x +2)^-1 (-e^-x) dx = ? and if I follow the equation above, I got denominator zero, for I broke the rules 'n is not equal to zero' I think I did as the equation. but now what should I do now?
