GDF Plotter - Mathematical grapher
GDF is a freeware program that allows you to draw any single variable mathematical function, circumferences, ellipses, parabolas, hyperbolas and sheaves of functions on a Cartesian coordinate system.

Graph functions, circumferences, ellipses, parabolas, hyperbolas and function families.
Automatic scan relative maximum and minimum on a graph providing 15 digit precision float values.
tendency icon (increasing/decreasing) when traversing graphics.
Defining or editing a graphic is easy by means of the Edition Object window as shown below. You just click type of graph you want to create or edit and fill the form specifying value such as the coordinate for the focus, center, etc. It assumes you're familiarized with descriptive geometry concepts and curves definition.
In order to insert functions such as 'log','exp', etc, while editing, you can select part of the text of the equation using the mouse and click on the built-in function you want to apply it, using the 'insert' menu. In example, if you wrote x^2+x+1 and want to get x^2+log (x+1): you must paint "x+1" form first equation and click 'logarithm' from insert menu.
|exp||Powered number 'e'||/||Division|
|gamma||Gamma function||\||Integer División (result will be truncated)|
|lngamma||Napierian Logarithm of function gamma|| Note: All trigonometric functions works with decimal grades..
|log||Logarithm base 10|
