Function Analyzer

Function Analyzer is a program that permits you to see the graph of a function likef(x)=. In this picture you can see the graph of this function:f(x)=1/Cos(x)/(1/X) The usage is very simple:- Write the function expression in the bottom combo Box or choose and modify a predefined one (see the list of recognized keywords).- Press the `Analyze` button to show the graph. After this you can:- MOVE the X,Y axis, zoom in/out, increase/decrease Precision (more precision you use more time the program take to process the expression). In order to parse Complex expressions I`ve created a parser using Gold Parser Builder by Devin Cook giving it a BNF rule grammar created by me ;-).After this, the GOLD Parser Builder creates a skeleton program I`ve used to parse expressions.The BNF sintax used is present in the program installation folder (expression.grm).
