My question is about assigning the resulting expression after evaluation of a function.
So what I want:
FOCf[x, y] := D[f[x, y], x]
such it immediately evaluates the right hand side, making it a conditional expression.
How I do it now.
I first shift-enter:
D[f[x, y], x]. Then, I manually copy the resulting output to the right end of
FOCf[x, y] :=.
Is there a better way to do this? I already tried using
Evaluate, but that did not seem to work.
