integral of-cos(x)sin^2(x)

\int - cos (x) sin^{2} (x) d x

- \frac{sin ^{3} ( x )}{3} + C

Solution steps

\int - cos (x) sin^{2} (x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int cos (x) sin^{2} (x) d x

Apply u-substitution

: \int u^{2} d u

= - \int u^{2} d u

Apply the Power Rule

: \frac{u ^{3}}{3}

= - \frac{u ^{3}}{3}

Substitute back

u = sin (x)

= - \frac{sin ^{3} ( x )}{3}

Add a constant to the solution

= - \frac{sin ^{3} ( x )}{3} + C

n = 2 \sum \infty \frac{5}{4 ^{n}}

\int_{2}^{4} \frac{1}{4 x - x ^{2}} d x

\frac{\partial}{\partial x} (x e^{9 x y})

\int_{4}^{10} 6 d x

\int k e^{- k^{2}}
