Derivative of tanh function in python

WebObtain the first derivative of the function f (x) = sinx/x using Richardson's extrapolation with h = 0.2 at point x= 0.6, in addition to obtaining the first derivative with the 5-point formula, as well as the second derivative with the formula of your choice . WebThese functions compute the forward and backward values of the tanh, sigmoid, and RelU functions, respectively. In each of these functions, the derivative is computed with regard to the element that is being input, and then the derivative that is produced is supplied in the opposite direction.
