Question

please hellllllppppppp!!
what is the integral of f^n(x).f'(x)dx

Answer 1

\[\int f^n (x) .f'(x) dx\]
put
\[f(x)=t\]
\[f'(x) dx=dt\]
so the integral becomes

\[ \int f^n (x) .f'(x) dx \longrightarrow \int t^n dt\]
Can you integrate now?

Answer 2

ok i can thanks

Answer 3

it is f^n+1/n+1+c

Answer 4

Yeah:D
