Missing an item from the formula

What I did

Fixed a mistake in code comments. Missing an item from the formula.

How I did it

Modify code comments with adding an item in formula.

+ (n+1)*D[j]**n/(n**n prod(x_i))

How to verify it

the correct newton's method formula is

There is an missing item in origin code comments.

Actually the numerator isn't correct either.

The whole thing should be:
D[j+1] = (A * n**n * sum(x_i) + n * D[j]**(n+1) / (n**n prod(x_i))) / (A * n**n + (n+1)*D[j]**n/(n**n prod(x_i)) - 1)

To get the calculation in the code, you need to replace A * n**n by Ann and D[j]**(n+1)/(n**n prod(x_i)) by D_p.
