2nd derivative of cost

[Olalekan Ogunmolu]

In the cost_utils.py file, I wanted to be sure that the 2nd derivative of l with respect to d, there should not be a power of 3 on the psq term. Correct?

It seems to me it should be to the power of 1.

The -3/2 power should come from taking the derivative of the sqrt twice, so I believe it should be a 3.

You are right, actually. Now that I check my solutions again, I see my error. Sorry for the bother.

Sincerely,

Lekan
