Question

Integration Help - II

Answer 1

\(\large\color{black}{ \displaystyle \int{}8x^3\sqrt{x^4+5} ~dx }\)

\(\large\color{black}{ \displaystyle \int{}x\cos(x^2)~dx}\)

(I am using x, but it can be any other letter, I am just used to x)

\(\large\color{black}{ \displaystyle \int{}x(x^4-1)~dx}\) (this is a little more advanced tho)
