Assuming I have a simple function such that f(x,y)=x^2+x*y+y is it possible with Mathcad Prime 3 to find the symbolic partial derivative of the function f'x(x,y)? For some reason I cannot find how to do this. f' seems to only give a normal first derivative. Is there some tricky keystroke to enable partial derivative notation in MC Prime 3? I find it hard to believe that PTC would have overlooked that functionality?
Kind regards, Mark
