integral of csc^2(2x)cot(2x)

\int csc^{2} (2 x) cot (2 x) d x

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

Solution steps

\int csc^{2} (2 x) cot (2 x) d x

Apply u-substitution

= \int - \frac{u}{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 u d u

Apply the Power Rule

= - \frac{1}{2} \cdot \frac{u ^{2}}{2}

Substitute back

u = cot (2 x)

= - \frac{1}{2} \cdot \frac{cot ^{2} ( 2 x )}{2}

Simplify

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

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

Add a constant to the solution

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