GrafEq - Version 2.10 GrafEq is a program for graphing implicit relations, such as those encountered in the high-school curriculum. GrafEq uses a different technique than other graphers, allowing it to plot relations such as "y=sin1/x", "x^2+y^2", "y=Arctan9^9^9(x-1)", "y=x/sinx", as well as inequalities and many other relations that stymie traditional techniques.
