Derivatives, Sigmoid Function, Tanh Function, Relu.
formula makes sense. So, for example, if z is equal to 10, Tanh of z will be very close to 1. This goes from plus 1 to minus 1. Then g prime of z, according to this formula, would be about 1 minus 1 squared, so there’s very close to 0. So, that was if z is very large, the slope is close to 0.
