C1_W1_Lab03_Cost function

Hi there! There was no application of this portion in the lab. We used built-in modules later to get a view of the cost function.
So, What is the purpose of this one there?

Hi farhana_hossain.

Many of the assignments will ask you to implement a function, even if it is not be used later on. The purpose is to help students better understand the key concepts explained in the course!

Help please - I am getting this error… tried formatting - I get the right output in the module above but now I get this…

@Matthew_Gaunt, maybe you can compare your code for compute_cost() with the code that’s given in the lab that’s referenced in the title of this thread (and is shown in the first post on this thread).
