Optimal result

Integrand size = 16, antiderivative size = 126 \[ \int \left (a+b \text {csch}^2(c+d x)\right )^{3/2} \, dx=\frac {a^{3/2} \text {arctanh}\left (\frac {\sqrt {a} \coth (c+d x)}{\sqrt {a-b+b \coth ^2(c+d x)}}\right )}{d}-\frac {(3 a-b) \sqrt {b} \text {arctanh}\left (\frac {\sqrt {b} \coth (c+d x)}{\sqrt {a-b+b \coth ^2(c+d x)}}\right )}{2 d}-\frac {b \coth (c+d x) \sqrt {a-b+b \coth ^2(c+d x)}}{2 d} \]
