integral of x^2cos(x)

integral

x^{2} cos (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

= 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 tan (2 x) sec^{3} (2 x) d x

\int \frac{( cos ( ln ( x ) ) )}{x} d x

\int tan (3 x + 1) d x

\int (5 x^{5} + 20 e^{4 x} + x + 10) d x

\frac{4}{x}
