integral from 0 to pi/2 of sin^6(θ)

\int_{0}^{\frac{π}{2}} sin^{6} (θ) d θ

\frac{5 π}{32}

Decimal Notation

0.49087 \dots

Solution steps

\int_{0}^{\frac{π}{2}} sin^{6} (θ) d θ

Apply Integral Reduction

= - [\frac{cos ( θ ) sin ^{5} ( θ )}{6}]_{0}^{\frac{π}{2}} + \frac{5}{6} \cdot \int_{0}^{\frac{π}{2}} sin^{4} (θ) d θ

\int_{0}^{\frac{π}{2}} sin^{4} (θ) d θ = \frac{3 π}{16}

= - [\frac{cos ( θ ) sin ^{5} ( θ )}{6}]_{0}^{\frac{π}{2}} + \frac{5}{6} \cdot \frac{3 π}{16}

Simplify

- [\frac{cos ( θ ) sin ^{5} ( θ )}{6}]_{0}^{\frac{π}{2}} + \frac{5}{6} \cdot \frac{3 π}{16} : - [\frac{1}{6} sin^{5} (θ) cos (θ)]_{0}^{\frac{π}{2}} + \frac{5 π}{32}

= - [\frac{1}{6} sin^{5} (θ) cos (θ)]_{0}^{\frac{π}{2}} + \frac{5 π}{32}

Compute the boundaries:

0

= - 0 + \frac{5 π}{32}

Simplify

= \frac{5 π}{32}

\int_{0}^{\infty} 4 e^{8 x} d x

\int_{0}^{1} \frac{1}{x ^{2} + x} d x

\int_{0}^{2} \frac{2 v}{v + 1} d v

\int_{- 2}^{0} \frac{2 x}{x ^{2} - 4} d x

\int_{1}^{\infty} \frac{3}{2 x - 1} d x
