Forward Propagation, Backward Propagation.
The multiplication here are a dot product. Output dA[l-1], dW[l], db[l] Next, let’s talk about the backward propagation step. Here, your goal is to input da^l, and output da^l minus 1 and dw^l and db^l. Let me just write out the steps you need to compute these things. Dz^l is equal to da^l
