SolveABinomialInTheThirdCaseWithASymbolicExponent​(AngouriMath.​Entity,​AngouriMath.​Entity.​Variable)

 Method (no overloads)

Summary

A binomial differential x^m (a + b x^n)^p with a symbol in its exponents, in
Chebyshev's third case at a whole (m + 1)/n + p + 1 = -k of at most 0: Rubi's
1/(a + b x^n)^((1 + 2 n)/n).

Remarks

At k = 0 the integral is x^(m + 1) (a + b x^n)^(p + 1)/(a (m + 1)), whose
derivative is the integrand there. Below it Rubi's reduction raises p by one,
J(p) = -x^(m + 1) (a + b x^n)^(p + 1)/(a n (p + 1)) + (m + 1 + n (p + 1))/(a n (p + 1)) J(p + 1)

and k steps of it reach the first. SolveABinomialDifferential(AngouriMath.Entity,AngouriMath.Entity.Variable) reads
the three cases with numbers for the exponents; with a symbol, a power of x beside the
binomial at k = 0 is SolveAsTheDerivativeOfAProductOfPowers(AngouriMath.Entity,AngouriMath.Entity.Variable,System.Boolean)'s, which
leaves a power on its own and every k past 0, and those were declined: Rubi's
1.1.3.2:3301-3304. The answer is differentiated back at sampled points before it is
returned.
