May be that the formula is...
(1)
... and if the are independent variables that's true...
Kind regards
Hello all,
I am having a hard time understanding how to differentiate summation operators. More specifically, I was given the following solution that I do not understand. Any step by step advice (or a link) would be fantastic....
I do not understand why this is equal to p, not the sum of p
Thank you kindly for the help,

As the others are implying, what you have written makes no sense. The sum depends on many different variables, labeled , , ..., but you are differentiating with respect to "x" which is not any of the variables!
What you have is something like where you are differentiating a function of y and z with respect to "x". That derivative is, in fact, 0!
But the partial derivatives of , , and
I do not understand why this is equal to p, not the sum of p
Thank you kindly for the help,
