Primitive of x by Inverse Hyperbolic Sine of x over a

Theorem

 * $\displaystyle \int x \sinh^{-1} \frac x a \rd x = \paren {\frac {x^2} 2 + \frac {a^2} 4} \sinh^{-1} \frac x a - \frac {x \sqrt {x^2 + a^2} } 4 + C$

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

let:

and let:

Then:
