I frequently use Google's ability to plot functions to get a quick view of what a function looks like, for example: sin(x), x^3.

However, some operators that work when given a number, like 3! * x, which plots 6*x, don't seem to work when applied to the x variable: 3! * x! doesn't give a plot at all.

I have failed to use the factorial operator (x!), and the modulous operator (x mod 3).

Is there a reference, documentation or whatever specifying the syntax for google's graphical calculator? I know it can do some pretty advanced things like plot functions in 3D over a specified range, but trying to use these features by hitting at random in the dark is kind of sub-optimal.

Why don't you use wolfram alpha? – CyberDude Dec 11 '12 at 9:47
@CyberDude because I have google as my search bar provider :), and because my (quite slow) computer tends to lag a lot with Wolfram Alpha, which makes frequent edition of the function a pain (when trying to get a specific shape, for example). When I need some more complex plots, I go to Wolfram Alpha, but I'd like to be able to use google for simple plots, without having to guess the syntax. – Georges Dupéron Dec 11 '12 at 19:35
I'd also like for them to support modulus. Wolfram Alpha won't let you zoom and pan around the plot without a "Pro" account. I guess you get what you pay for. – super_aardvark Feb 2 at 0:14
