Primitive of Inverse Hyperbolic Cosecant of x over a

Theorem

 * $\ds \int \csch^{-1} \frac x a \rd x = \begin{cases}

x \csch^{-1} \dfrac x a + a \sinh^{-1} \dfrac x a + C & : x > 0 \\ x \csch^{-1} \dfrac x a - a \sinh^{-1} \dfrac x a + C & : x < 0 \end{cases}$

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:
