3D Graph of f(x,y) for -3≤x,y≤3

[MAins]

> f:=(x,y)->(x+3*y -1)*e^(-(x^2)-(y^2));
> plot3d(f(x,y),x=-3..3,y=-3..3);

I'm supposed to plot for -3 less than or equal to x,y less than or equal to 3... Does that mean x=y at a given point? Anyway, I rewrote it as above and Maple does not show an error but rather shows just a blank space where the graph is supposed to be. Any suggestions?

Your input isn't formatted properly from what I can see. I assume by the e^ you want to use the exponential function right? Maple will evaluate 'e' as an undefined constant. If you want to use the exponential function, you must use exp(),

i.e. exp(-x^2-y^2)

see if that helps

Hello,

Thank you for sharing your concern. I can provide some possible explanations for why the graph is not being displayed.

1. The function may not have a well-defined graph for the given range of values. This could happen if the function has a singularity or a discontinuity in the specified range. In such cases, the graph may appear blank or distorted.

2. The software used to plot the graph may not support the given function or may have limitations in plotting three-dimensional graphs. It is always recommended to check the documentation or user manual of the software to ensure that the function can be plotted correctly.

3. The function may have a very small or large range of values, which may not be visible on the given scale of the graph. In such cases, adjusting the scale or using a different visualization technique may help in displaying the graph.

I suggest checking for these possibilities and making appropriate changes to see if the graph can be displayed correctly. If the issue persists, it would be helpful to provide more information, such as the software used and any error messages, to further troubleshoot the problem.

Best regards,
