I have to use implicitplot3d to plot a quadric surface in Maple, the function definition is as follows:

$\displaystyle x^2/9+y^2/36=1-z^2/25$

I cannot determine how to enter this into the command line for Maple. It does not render properly when I type the function rule as x^2/9+y^2/36=1-z^2/25, probably for obvious reasons.

Is there anyone with experience who can inform me how to enter the function into the Maple command?
