Maple problems

  1. I'm not at all familiar with maple, and I tried the help on Maple but I'm just not getting what it says. Here is the question,

    f(x,y)= x^2-y^2. Show cross-sections for x=1, y=2. Show the tangent plane through (1,2,-3). Show the gradient vector at (1,2). Use the Vector Calculus package (below) to demonstrate gradient vector field.

    with(VectorCalculus):
    Gradient (X^2 + Y^2, [X,Y];

    Thanks for the help
