Question

How do you integrate the integral of
(x^3) * (sin(x^2)) dx

Answer 1

\[\int x^3 \sin{(x^2)}dx\]
Have you tried integration by parts?

Answer 2

\(u = x^2\)

Answer 3

\(du = 2xdx\)

Answer 4

i would write it as
\[\int x^2\times x\sin(x^2)dx\] and then try parts

Answer 5

what @wio said
you get
\[\frac{1}{2}\int u \sin(u)du\]
parts for this one

Answer 6

Thank you both for your help!
