integral of x^2*cos(x)

\int x^{2} \cdot 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

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

\frac{d}{d x} (6 cos (4 x))

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

x y^{^{'}} + (1 + x) y = e^{- x} sin (2 x)

d er i v a t i v e f (x) = [(4 x^{2} + 3 x) cos (x)]
