    Are you taking the root of the whole function or just x^19?

    This ones a beast??? integral sqrt(x^19) sin(4+x^21/2) dx = (2 sqrt(pi) sqrt(x^19) (sin(4) C(x^(21/2)/sqrt(pi))+cos(4) S(x^(21/2)/sqrt(pi))))/(21 x^(19/2))+constant

    They are called Fresnel integrals, said it was a beast to solve, I gather you've not come across them?

    This is a difficult function to integrate, the pi value is a property of the Fresnel integral process? Ther is another method using erf??
