Complete the LINEAR part of a layer's forward propagation step (resulting in. [-0.2298228 0. We know it was a long assignment but going forward it will only get better. Implement forward propagation for the [LINEAR->RELU]*(L-1)->LINEAR->SIGMOID computation, X -- data, numpy array of shape (input size, number of examples), parameters -- output of initialize_parameters_deep(), every cache of linear_activation_forward() (there are L-1 of them, indexed from 0 to L-1). Now, similar to forward propagation, you are going to build the backward propagation in three steps: Suppose you have already calculated the derivative.
