Question

When doing integration by parts, what's a good tip to choose which one to be f'(x) and which one g(x)?

Answer 1

\[\int\limits_{0}^{1}x ^{2}e ^{x}dx\]
For example, this one I originally chose f'(x) = x^2 and g(x) = e^x only to find out it doesn't work well

Answer 2

yeah try integration by parts here
\[\int\limits_{0}^{1}x ^{3}e ^{x}\]
let u=x^2 and v=e^x

Answer 3

mark I figured out how to do it thanks though

Answer 4

thanks mark

Answer 5

im sorry
x=3 and v=e^x

Answer 6

ok yw, have fun thnx
