Question

what is the intgral of xe^x

Answer 1

Try integration by parts.

Answer 2

do you set x equal to u or e^x

Answer 3

LIPET,
Log, inverse trig, polynomial, expontial, trig
So you should set x as U

Answer 4

Integration by parts u=x, dv=e^x dx

Answer 5

integral of xe^x dx
= 1/2 x^2 e^x + c
or using chaguanas step...
u = x
du = dx
then
integral u e^x du
= e^x integral u du
= e^x 1/2 u^2 + c
then let u = x
= e^x 1/2 x^2 + c
