Derivatives, Sigmoid Function, Tanh Function, Relu.
slope is actually equal to 1, which is actually the slope when z is equal to 0. So, just to summarize, if a is equal to g of z, so if a is equal to this Tanh of z, then the derivative, g prime of z, is equal to 1 minus a squared. So, once again, if you’ve already computed the value of a, you can
