integral of cos^3(x)sin^{10}(x)

\int cos^{3} (x) sin^{10} (x) d x

\frac{sin ^{11} ( x )}{11} - \frac{sin ^{13} ( x )}{13} + C

Solution steps

\int cos^{3} (x) sin^{10} (x) d x

Rewrite using trig identities

= \int (1 - sin^{2} (x)) cos (x) sin^{10} (x) d x

Apply u-substitution

= \int u^{10} (1 - u^{2}) d u

Expand

u^{10} (1 - u^{2}) : u^{10} - u^{12}

= \int u^{10} - u^{12} d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int u^{10} d u - \int u^{12} d u

\int u^{10} d u = \frac{u ^{11}}{11}

\int u^{12} d u = \frac{u ^{13}}{13}

= \frac{u ^{11}}{11} - \frac{u ^{13}}{13}

Substitute back

u = sin (x)

= \frac{sin ^{11} ( x )}{11} - \frac{sin ^{13} ( x )}{13}

Add a constant to the solution

= \frac{sin ^{11} ( x )}{11} - \frac{sin ^{13} ( x )}{13} + C
