Exploring a Graph As in function graphing, you can explore a graph by using the following tools. Any displayed coordinates are shown in rectangular or polar form as set in the graph format. Tool Free-Moving Cursor „ Zoom ... Trace For Differential Equation Graphs: Works just as it does for function graphs. Works just as it does for function graphs. • Only x (xmin, xmax, xscl) and y (ymin, ymax, yscl) Window variables are affected. • The t Window variables (t0, tmax, tstep, tplot) are not affected unless you select 6:ZoomStd (which sets all Window variables to their standard values). Lets you move the cursor along the curve one tstep at a time. To move approximately ten plotted points at a time, press 2 B or 2 A. If you enter initial conditions in the Y= Editor or let the ncurves Window variable plot curves automatically, you can trace the curves. If you use: HŠ IC from the Graph screen to select initial conditions interactively, you cannot trace the curves. QuickCenter applies to all directions. If you move the cursor off the screen (top or bottom, left or right), press ¸ to center the viewing window on the cursor location. Use C or D to view results on all plotted curves.
