This is a graphing calculator that can plot any equation, as long as you write it in the program's scripts. There is already a sine wave loaded, but you can do tangents, squares, and more. There are more instructions once you go inside the project. Remix if you want to show off a design. It will be graphed instantly if you go into turbo mode.
