A&G Grapher can draw any 2D or 3D mathematical equation. Equations can be of any complexity, thus it is not required to always start an equation with y= or z= because the graphing software is programmed to handle any combination of x y z variables. Equations can be as simple as y=sin(x) or as complex as y+xy = sin(x). There are also several tools included for analyzing and modifying the plotted graphs. These tools can be used for rotation,...
