integral of sqrt(sin(2x))cos(2x)

\int sin (2 x) cos (2 x) d x

\frac{1}{3} sin^{\frac{3}{2}} (2 x) + C

Solution steps

\int sin (2 x) cos (2 x) d x

Apply u-substitution

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

= \int sin (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 (u) cos (u) d u

Apply u-substitution

: \int v d v

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

Apply the Power Rule

: \frac{2}{3} v^{\frac{3}{2}}

= \frac{1}{2} \cdot \frac{2}{3} v^{\frac{3}{2}}

Substitute back

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

Simplify

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

= \frac{1}{3} sin^{\frac{3}{2}} (2 x)

Add a constant to the solution

= \frac{1}{3} sin^{\frac{3}{2}} (2 x) + C

f (x) = \frac{1}{5} x - \frac{1}{2}

\int 8 x^{7} d x

\frac{x ^{\frac{3}{2}}}{3}

\frac{e ^{- 2 s}}{s ( 3 s + 2 )}

\frac{\partial}{\partial y} (y - x)
