Question

integrate (X^2-x +1) sin x dx

Answer 1

\[\int\limits( x^2 +x+1) \sin x dx\]

Answer 2

Looks hella like you could use integration by parts.

Answer 3

if i expand this, I get
\[\int\limits (x^2 \sin x + x \sin x + \sin x) dx\]
then I sould just do \[\int\limits u dv= uv- \int\limits v du \]
for each

Answer 4

That is a way to do it, yes.
