Welcome to the GM-84 Plus graphing calculator!

Left panel: Type in equations to graph. Options: choose color, hide/show, trace mode (move your mouse in the plane to see x-y values), solution (show left-most visible solution).

Features: Zoom in/out with mouse scroll, pan any direction by dragging/dropping with your mouse (or zoom and pan using buttons at the bottom right).

Y= button shows/hides the left panel.

Blue buttons allow you to adjust the window, i.e. determine which parts of the x-y plane are visible. Options: Z-Standard (-10 to 10, the default); Z-Square (makes x and y units equal size); or custom.

Animate shows you how your graph changes as the value of the variable c changes. The graph will only look animated if your equation includes a variable c, as the two initally loaded equations do. You can adjust the min/max of c on either side of the slider.
