8-5 Drawing Graphs Manually
After you select the RUN icon in the Main Menu and enter the RUN Mode, you
can draw graphs manually. First press ! 4 (Sketch) 5 (GRPH) to recall the
Graph Command Menu, and then input the graph function.
u u u u u To graph using rectangular coordinates (Y =)
You can graph functions that can be expressed in the format
1. In the set up screen, specify "Y=" for Func Type and then press J.
2. Input the rectangular coordinate (Y =) expression.
3. Press w to draw the graph.
View Window settings are made automatically for built-in graphs.
• {Y=}/{r=}/{Parm}/{X=c}/{G%dx} ... {rectangular coordinate}/{polar coordinate}/
{parametric}/{X = constant}/{integration} graph
• {Y>}/{Y<}/{Yt t t t t }/{Ys s s s s } ... {Y>f(x)}/{Y<f(x)}/{Y>f(x)}/{Y<f(x)} inequality graph
