Usage

Clearing lines

You can click the "Clear lines" button to clear all the functions currently on the screen.

Entering equations

There's a text box in the top-right where you can type in functions that you want to draw to the screen. The notation used is fairly intuitive and is similar to how you would write it.

Once you're satisfied with the text you've typed, you can press the enter key to draw it to the screen.

Finding the list of equations

By hitting the "Show info" button, you can view which functions are on the screen and which equation types are supported.
Here's our log_2(x):

Multiple equations

You can also enter multiple functions at the same time.

Notation

You can enter functions with or without a "y=" in them, but there will always be a "y=" implied. Here are some examples of the notation used:
y=3x
4x^2
5*4^x+3
5abs(3x)
-2log_3(5x)+3
y=-x
