Question

integrate: xe^(x^2)

Answer 1

Hint: u = x^2

Answer 2

What's du?

Answer 3

du is 2x

Answer 4

2xdx

Answer 5

correct

Answer 6

you have xdx, u need the 2

Answer 7

So you put a 2 after the integral, and a 1/2 before the integral?

Answer 8

correct sir

Answer 9

Still need help?

Answer 10

Thanks, I ot it. it's 1/2e^x^2

Answer 11

+c

Answer 12

thanks

Answer 13

\begin{align}
\int xe^{x^2} &= \text{let} \ u= x^2 \ , \ du = 2xdx \iff \cfrac{du}{2} = xdx \\
&= \cfrac{1}{2} \int e^u du \\
&= \cfrac{1}{2} e^u+c \\
&= \cfrac{1}{2} e^{x^2} +c
\end{align}
