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.

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…
