Integral of normal distribution
I thought i made a discovery that the Sigmoid function was the integral of the Normal Distribution whose integral according to normal calculus has no solution. Unfortunately i was beaten by a few years https://www.sciencedirect.com/science/article/abs/pii/0096300395001905 This is my effort in basic on the caprice amstrad emulator showing a plot of the normal distribution integral and the sigmoid function overlapping exactly. This is a hot peice of maths for a good mathematician like Terence Tao or Grant Sanderson, 3 blue one brown youtube to prove.
