integral of (sin^3(x))(cos(x))

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

\frac{sin ^{4} ( x )}{4} + C

Solution steps

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

Apply u-substitution

: \int u^{3} d u

= \int u^{3} d u

Apply the Power Rule

: \frac{u ^{4}}{4}

= \frac{u ^{4}}{4}

Substitute back

u = sin (x)

= \frac{sin ^{4} ( x )}{4}

Add a constant to the solution

= \frac{sin ^{4} ( x )}{4} + C

\int 3 x (x^{2} - 2)^{5} d x

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

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

\int x^{2} e^{- 12 x} d x

\int \frac{1}{x ^{2} + 8 x + 3} d x
