SolveAPowerOfAnImaginaryHyperbolicCosecantSumInTheExponential​(AngouriMath.​Entity,​AngouriMath.​Entity.​Variable,​System.​Boolean)

 Method (no overloads)

Summary

A power of a ± i a csch(y), not whole, integrated in w = e^y: there
csch(y) is 2 w/(w^2 - 1) and the sum is a (w ± i)^2/(w^2 - 1), so its power is
a^p (w ± i)^(2p) (w^2 - 1)^(-p) times a constant on every interval where both are
continuous, and dy = dw/w.

Remarks

Rubi's sqrt(a + i a csch(c + d x)) and the rest of 6.6.3's were declined: the sum is
the square of a complex function over a real one, which nothing read. The constant is not
written: the answer is the integrand times the antiderivative in w over what that
antiderivative differentiates back to, a quotient constant wherever it is continuous; and it
is kept only where its derivative is the integrand at the sampled points.
