integral of xcos(x)x

\int x cos (x) x d x

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

Solution steps

\int x cos (x) 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 (2 - 7 x)^{\frac{2}{3}} d x

\int tan (x) sec^{\frac{5}{4}} (x) d x

\int \frac{cos ^{3} ( 3 x )}{sin ^{4} ( 3 x )} d x

\int (2 x + sin (3 x)) d x

\int p^{2} e^{p^{3}} d p
