RE: Entering partial derivatives?
Is there a short way to test a point (1,2) on the partial with respect to x?

diff((f(x,y),x)|x=1,y=2 doesn't work.
diff((f(x,y),x|x=1,y=2) doesn't work.
diff(f(x,y),x)|assume(x = 1,y = 2) doesn't work.
(diff(f(x,y),x)|(assume(x = 1,y = 2))) doesn't work.
(f(x,y),x)'|x=1,y=2) doesn't work.
