integral of sin^4(2x)cos(2x)

\int sin^{4} (2 x) cos (2 x) d x

\frac{1}{10} sin^{5} (2 x) + C

Solution steps

\int sin^{4} (2 x) cos (2 x) d x

Apply u-substitution

: \int sin^{4} (u) cos (u) \frac{1}{2} d u

= \int sin^{4} (u) cos (u) \frac{1}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int sin^{4} (u) cos (u) d u

Apply u-substitution

: \int v^{4} d v

= \frac{1}{2} \cdot \int v^{4} d v

Apply the Power Rule

: \frac{v ^{5}}{5}

= \frac{1}{2} \cdot \frac{v ^{5}}{5}

Substitute back

= \frac{1}{2} \cdot \frac{sin ^{5} ( 2 x )}{5}

Simplify

\frac{1}{2} \cdot \frac{sin ^{5} ( 2 x )}{5} : \frac{1}{10} sin^{5} (2 x)

= \frac{1}{10} sin^{5} (2 x)

Add a constant to the solution

= \frac{1}{10} sin^{5} (2 x) + C

\frac{\partial}{\partial x} (A x + b y^{2} + c x^{2} y)

f (x) = 4 x^{2} + 4 x, (- 2, 8)

\int - 8 x e^{x} d x

\int sin (x) \cdot sin (2 x) \cdot sin (3 x) d x

\int \frac{x}{x - 17} d x
