Upon opening Graphmatica, you’ll see something like this:

Graphmatica’s default color scheme is set to black; to make it normal like my color scheme, go to Options>Graph Paper>Color and set the color scheme to something other than “Black.” Graphmatica has the ability to graph in the Cartesian plane and the Polar plane. You can easily switch between what the graph paper shows by switching a few options. Below is a screenshot of two different functions from different planes:

Simply type and press enter into the bar under the menu bar to display a function. Notice how I used “theta” for theta in the polar graph. It is possible to capture images of these functions and then print them out. To modify or delete functions, right click on the graph of a function, and choose an option from the pop up menu. Graphmatica can also draw the derivative of a function, and integrate them, through the “Calculus” menu.

Graphmatica supports a wide variety of functions, most of which I have never heard of and are probably beyond high school mathematics. Below is the Operator table from the Help menu:

Now, for Graphmatica’s rating:
