Primitive of Power of x by Inverse Hyperbolic Cotangent of x over a

Theorem

 * $\ds \int x^m \arcoth \frac x a \rd x = \frac {x^{m + 1} } {m + 1} \arcoth \frac x a - \frac a {m + 1} \int \frac {x^{m + 1} } {a^2 - x^2} \rd x + C$

Proof
With a view to expressing the primitive in the form:
 * $\ds \int u \frac {\d v} {\d x} \rd x = u v - \int v \frac {\d u} {\d x} \rd x$

let:

and let:

Then:
