Procedure

1. Go to desmos.com.

2. Click "Graphing Calculator." (You may also select a different calculator—scientific, four-function, matrix, etc.—by clicking "Math Tools" at the very top of the screen.)

3. Click the "Add Item" (plus sign) button in the top-left corner to add an expression, note, table, folder, or image to the input row (expression list bar) on the left. You may also type an equation and press "Enter" or click the next input row to enter another function.

4. Optional: Click the "Keypad" button in the bottom-left corner to access special functions or characters. (Everything available from the Keypad is also available via keyboard shortcuts.)

5. Use the "Graph Settings" (wrench icon) button in the top-right corner to adjust graph settings such as a rectangular or polar coordinate plane, radians or degrees, etc.

6. Logging in or signing up is optional. If you are logged in, save your graph to make later edits or to share with others. Use the three vertical lines in the top-left corner to save your work.
