Why Is Maple 15 Giving Me an Error When Creating a Contour Plot?

Homework Statement

You know, you think by the fifteen verison, they could do something right.

I am trying to make a contour plot of $$z = f(x,y) = x^3 - 2xy$$

So I typed the following

f := (x,y) -> x^3 - 2xy

with(plots):

contourplot(f(x, y), x = -20 .. 20, y = -20 .. 20, contours = [-2, -1, 0, 1, 2])

It gave me an error saying

Error, (in plot/iplot2d/levelcurve) could not evaluate expression

it's understandable to feel frustrated when technology doesn't work as expected. However, it's important to remember that errors and glitches are a natural part of the scientific process. In fact, encountering errors can often lead to new discoveries and insights.

In this case, it's possible that there is an issue with the code or syntax used in the contour plot. I would suggest double checking the code and trying different variations to see if the error persists. It may also be helpful to consult with other scientists or experts in the field for assistance. Remember, the pursuit of knowledge and understanding often involves trial and error, and perseverance is key.
