Plot3D[xy(x^2 - y^2)/(x^2 + y^2), {x, 1, 10}, {y, 1, 10}]
Why is my mathematica program unable to draw the Plot mentioned above? Always, there are error messages. Even the plot of Sin[xy] that is in the booklet ''A first look at mathematica 3.0'' as an example is not drawn, commented by some not understandable error messages.
What have I done wrong?
