integral of csc^2(2ax)

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

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

Solution steps

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

Apply u-substitution

= \int \frac{csc ^{2} ( u )}{2 a} d u

Take the constant out:

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

= \frac{1}{2 a} \cdot \int csc^{2} (u) d u

Use the common integral:

\int csc^{2} (u) d u = - cot (u)

= \frac{1}{2 a} (- cot (u))

Substitute back

u = 2 a x

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

Simplify

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

Add a constant to the solution

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