integral of x^2(cos(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

\int \frac{cos ( t )}{( 4 sin ( t ) + 12 ) ^{2}} d t

\int cos^{4} (t) sin^{2} (t) d t

\int cos (x) d (sin (x)) d x

\int x^{2} \cdot 5^{(x - 1)} d x

\int e^{a t} e^{- s t} d t
