Flammable Maths: An Insane Approach! The Fresnel integrals: sin(x^2) and cos(x^2) without complex analysis at https://www.youtube.com/watch?v=iCwiDPL3EMI Writing math by hand is a bad thing to do to new generations. Get a decent symbolic math editor/solver and at least make the symbols standard. Do you trust programmers who make canned math manipulation tools, or some old guy
