I have the following function (with parameters/constants a, b, and p2A ):
I want to calculate its partial derivative with resprect to p1A. I entered the following code to do this:
But this returns a result that was (at least, for me) unexpected:
My problem is, I don't really get what the expressions 'D(...)' mean in this equation and why they are even there. a and p2A are supposed to be constant and thus their derivative should be zero (wtih respect to p1A ).
I think this should be an easy problem to solve for someone more familiar with Maple, but I am new to it and have been spending the last few hours trying to figure out how to solve this problem. Any help would be highly appriciated.
Thank you in advance,
