# Thread: plot multivariable function - stupid question?

1. ## plot multivariable function - stupid question?

Is is possible to plot a multivariable funciton? How?

Sorry if this is a stupid question, but, as I have read in a forum signature "The only stupid question is the one you don't ask. The only stupid person is the one who pretends to know."

Thanks.

Anyway, so, basically, z is the dependent variable whereas x and y are independent variable, right?

what does the notation $z = f(x,y)$ indicate ?

5. Yeah right. That was pretty straight forward, but there's no reason for sarcasm though. Thanks anyway.
