MHB Can You Help Me Integrate $\sin(u) + u^6$ Correctly?

[jaychay]

Can you please help me ?
I have tried to do it many times but still got the wrong answer.
Thank you in advance.

Make the substitution $t = \sin x$.

Get the parentheses in the right place! It's not $\sin(u+u^6)$, but $\sin(u) + u^6$, which is much easier to integrate.
