I'm in Abstract algebra and none of my teachers in any of my previous classes explained where the 4p came from. Thank you for finally telling me.

Wow, I was wondering where the 4 came from in the 4py. Excellent video as always, thank you Professor!

Wouldn't we say y = X^2/4p instead? As y is a function of x

I search for this on the FE Review Manual, because I'm studying for the Electrical exam, and in the book and the Online Manual the general equation is different, it said that
 x^2 = 2py, can you explain me why you said is x^2 = 4py?
