Version: 3.0
Release Notes:
This version includes an algebra expression to JS expression translator. This means the user may enter an expression such as 2sin(x)^3 and this will be translated to the JS expression: 2*Math.pow(Math.sin(x), 3). The engine includes error checking and can identify syntax errors and unbalanced parentheses. However, due to the translator's design stray lower-case letters will be identified as variables. Such as in the expression glog(x), 'g' would be assumed to be a second variable because it is not part of a known function name. This is not a problem for the translator, but it does cause errors in the main graphing loop which does not recognize the unintentional letter. The help page displays what variable names are to be used with each graphing mode: x with Rect, t with Para, t with Polar.
