Calculator

A calculator written in python and kivy with a standard calculation mode and a graphing mode using reverse polish notation
and the shunting yard algorithm. Currently all the standard operators such as +,-,/,* (including unary - and +) and ^
are implemented as well as sin,cos and tan (in radians).

Also in the graphing mode there is support for animation by adding a variable and setting a maximum and minimum
then pressing the “play” button.

Known Issues:

• In graphing mode equations like (x+3)(x-2) do not work as a * must be put in between them

Todo:

• Add automatic changing of the grid line frequency and labels on zoom in/out
• Adjust how zooming is handled, make it so that it zooms around the mouse point
• Add adjustable precision (decimal module?) so jagged lines don’t start showing when zoomed in
• Add parametric equations
