integral of 2sin^3(x)cos(x)

\int 2 sin^{3} (x) cos (x) d x

\frac{1}{2} sin^{4} (x) + C

Solution steps

\int 2 sin^{3} (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^{3} (x) cos (x) d x

Apply u-substitution

: \int u^{3} d u

= 2 \cdot \int u^{3} d u

Apply the Power Rule

: \frac{u ^{4}}{4}

= 2 \cdot \frac{u ^{4}}{4}

Substitute back

u = sin (x)

= 2 \cdot \frac{sin ^{4} ( x )}{4}

Simplify

2 \cdot \frac{sin ^{4} ( x )}{4} : \frac{1}{2} sin^{4} (x)

= \frac{1}{2} sin^{4} (x)

Add a constant to the solution

= \frac{1}{2} sin^{4} (x) + C

\int e^{t^{2}} d t

\frac{e ^{- 3 s}}{s - 3}

\int \frac{4 x ^{2}}{( 1 - 8 x ^{3} ) ^{4}} d x

y^{^{'}} - \frac{y}{x} = 1

\int \frac{x}{a - x} d x
