Hello! I hope you are doing well.
This is Exercise 4 - gradient_check_n of week 1 of DLS course 2. I don’t know where I am making mistakes. Kindly guide me.

PS: I will share my code here for a time being, if necessary.
Please click my name and message your notebook as an attachment.
Okay. I am sending it.

Calculations of db1 and dW2 are incorrect in backward_propagation_n.
Inside gradient_check_n, calculation of theta_minus[i] is incorrect. The name of the variable hints whether you should add or subtract epsilon

Oh, such a silly mistake. I am an idiot. Thanks a million, Balaji, for correcting me.
Regarding db1 and dW2, those incorrect equations are the part of the assignment. So, we can see that the Gradient check is high.
Once again, thanks a lot…
Saif.
