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

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

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

Solution steps

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

Apply u-substitution

= \int - u^{2} d u

Take the constant out:

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

= - \int u^{2} d u

Apply the Power Rule

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

Substitute back

u = cos (x)

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

Add a constant to the solution

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