Answer 1

Did you try integration by parts?

Answer 3

Which one should be u and which one should be dv?

Answer 4

Thanks

Answer 5

Do something before by parts.
Let u=x^7 => du = 7x^6 dx => x^6 dx = du/7

\[\int x^{13}sin (x^7) dx\]\[=\int x^{7}sin (x^7) (x^6dx)\]\[=\int usin (u) (\frac{du}{7})\]\[=\frac{1}{7}\int usin(u)du\]Then, use integration by parts.
