Advanced Grapher is a plotting program that displays graphs of Cartesian [Y(x) and X(y)] coordinates, polar and parametric functions, implicit functions, inequalities, slope fields, and graphs of tables. It includes many sample graphs to illustrate various features of the program. You can display up to 30 graphs at a time with easy toolbar manipulation of coordinate intervals, view, fonts, and colors. Set parameters and get calculus answers for regression analysis, and both integral and differential equations. Save the graphs as .gif files or export them in .emf (Enhanced Windows Metafile) format to Word documents. You can also import and export data tables. There's lots of high-power math capability here. Ample documentation is included.
