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

integral

sin (t) cos^{2} (t)

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

Solution steps

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

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 (t)

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

Add a constant to the solution

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