Type in $2 * x$, not $2x$. Do not type in $\pi$ or divide by $0$. $e$ is acceptable.
Handles all basic arithmetic operations as well as $\cos, \sin, \tan, \arcsin, \arccos, \arctan, \text{ and} \ln$.
Does not handle hyperbolic trig functions as well as absolute values.
Note: if the equation in the graphing calculator does not show up, please press the box containing the equation and click one of your side arrows.
