Evaluate the definite integral:
[tex]\int u^n du/dx[/tex] = u^(n+1)/(n+1) (n not equal to -1)
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?
