Question

Integral of x*sin(x^2) , using u substitution if necessary?

Answer 1

Yes, you could use a U sub

Answer 2

is there anything there that is a derivative of another?

Answer 3

i kind of cheated and googled it, so, looks like the best bet is to set u = x^2, thereby, we can set x = 1/2 * du

Answer 4

\(\large u=x^2 \) and \(\large du=\frac{1}{2}x du \) Then yes

Answer 5

That should be dx at the end not du, sorry

Answer 6

and the derivative of x^2 is not 1/2 x

Answer 7

Yea, meant to put that outside near du, this Is embarrassing

\(\Large du=2x dx\ )

Answer 8

think I got it from there, will post the larger problem for completeness, thanks for the help
