integral of 2sin^5(x)cos(x)

\int 2 sin^{5} (x) cos (x) d x

\frac{1}{3} sin^{6} (x) + C

Solution steps

\int 2 sin^{5} (x) cos (x) d x

Take the constant out:

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

= 2 \cdot \int sin^{5} (x) cos (x) d x

Apply u-substitution

: \int u^{5} d u

= 2 \cdot \int u^{5} d u

Apply the Power Rule

: \frac{u ^{6}}{6}

= 2 \cdot \frac{u ^{6}}{6}

Substitute back

u = sin (x)

= 2 \cdot \frac{sin ^{6} ( x )}{6}

Simplify

2 \cdot \frac{sin ^{6} ( x )}{6} : \frac{1}{3} sin^{6} (x)

= \frac{1}{3} sin^{6} (x)

Add a constant to the solution

= \frac{1}{3} sin^{6} (x) + C

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

\int 1 d sin (x) d x

\int x (4 - x)^{5} d x

\int (x^{2} + \frac{1}{x ^{3}}) d x

\int sin (5 x - 2) d x
