integral of x^2cos(x)

\int x^{2} cos (x) d x

x^{2} sin (x) - 2 (- x cos (x) + sin (x)) + C

Solution steps

\int x^{2} cos (x) d x

Apply Integration By Parts

= x^{2} sin (x) - \int 2 x sin (x) d x

\int 2 x sin (x) d x = 2 (- x cos (x) + sin (x))

= x^{2} sin (x) - 2 (- x cos (x) + sin (x))

Add a constant to the solution

= x^{2} sin (x) - 2 (- x cos (x) + sin (x)) + C
