Very simple function does not run

[SimonKohn]

Friends,

after defining f(x,y): x / y , I tried to plot as an 3D chart.

Unfortunately, that's not possbile and resulting in an error message.

It doesn't like the fact that the function has a singularity when y = 0. Change the y axis start to something greater than 0.

Also, you only need type f rather than f(x,y) in the placeholder on the graph.

define ranges for x and y

Here is yet another approach which works in Prime only because the 3D component in Mathcad 15 and below does not accept NaN's.
