DRAWFUNC - 2d parametric curves drawing program

Gershon Elber
gershon@cs.utah.edu

This program allows drawing of 2D free form explicit algebraic curves of the form: x = X(t), y = Y(t), or y = f(x), where t is the parametric domain parameter. The program displays the curve by sampling, and approximating (with settable accuracy) it as piecewise linear polylines. It also possible to symbolically differentiate the curve and simultaneously display the curve and its 1st 2nd and 3rd derivatives. An on line help is available which can be modified.
