integral of x^2sin(x)cos(x

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

cos (d) (- x^{3} cos (x) + 3 (x^{2} sin (x) - 2 (- x cos (x) + sin (x)))) + C

Solution steps

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

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

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

Apply Integration By Parts

: - x^{3} cos (x) - \int - 3 x^{2} cos (x) d x

= cos (d) (- x^{3} cos (x) - \int - 3 x^{2} cos (x) d x)

\int - 3 x^{2} cos (x) d x = - 3 (x^{2} sin (x) - 2 (- x cos (x) + sin (x)))

= cos (d) (- x^{3} cos (x) - (- 3 (x^{2} sin (x) - 2 (- x cos (x) + sin (x)))))

Simplify

= cos (d) (- x^{3} cos (x) + 3 (x^{2} sin (x) - 2 (- x cos (x) + sin (x))))

Add a constant to the solution

= cos (d) (- x^{3} cos (x) + 3 (x^{2} sin (x) - 2 (- x cos (x) + sin (x)))) + C

\int (4 x + 3 x^{2}) d x

\int 3 sin (3 t) d t

\int \frac{1}{5 y - 1} d y

\int \frac{12}{x ^{2}} + 2 x + 2 d x

\int \frac{1}{( 1 - sin ( x ) ) ^{2}} d x
