Takes derivatives and definite integrals or anti derivatives of polynomials. Surprisingly complex script. I have seen other supposed solvers around here, but none which can handle polynomials in general form. Examples: 3x^4 - 27x^3 + 4x^2 + 2x - 8 26x^7 + 8x^3 - 9x^3 -5x^3 - 7x + 23 3x^3 + 9x - 21x^5 - 9x^6 2x^3 + 24x - 9 26 + 2x + 45x^2 3x^3 + 8x - 923x^56 + 2x^3 34x^3 + 7x - 9x^4 -2x + 9
