Integration in 2D and 3D and it also does simple series calculations. Equation Evaluator does function graphing, solution to expressions, integration in 2D and 3D and it also does simple series calculations.
Its a very simple software and was only intended on demonstrating the speed and abilities of the parser engine I had developed. A note on the parser engine is its unique capability to simplify expressions and re-order them so that they are executed as a list of sequential operations rather than a tree of prioritized expression this functionality leads to outstanding decrease in time needed to evaluate a particular expression which makes it ideal for repetitive evaluations of expressions where only the variables change value and not the expression itself, such as graphing a function or integrating an area.
