Pressing 1(SEL) while one of the function’s is highlighted would causes its “
R
” or “
B
”
indicator to be cleared. A function without an indicator is drawn as the main screen graph
(on the left side of the display).
Example Graph
y = x(x + 1)(x – 1) in the main screen and sub-screen.
Use the following V-Window settings.
(Main Screen) Xmin = –2, Xmax = 2, Xscale = 0.5
Ymin = –2, Ymax = 2, Yscale = 1
(Sub-screen) Xmin = –4, Xmax = 4, Xscale = 1
Ymin = –3, Ymax = 3, Yscale = 1

k Graphing in the Run-Matrix Mode
While the Linear input/output mode is selected, commands can be input directly in the
RUN
•
MAT (or RUN) mode to draw a graph.
You can select a function type for graphing by pressing !4(SKTCH)5(GRPH) and then
selecting one of the function types shown below.
• {Y=}/{r=}/{Param}/{X=}/{G ·
 dx} ... {rectangular coordinate}/{polar coordinate}/{parametric
function}/{X=f(y) rectangular coordinate}/{integration} graphing
• {Y>}/{Y<}/{Y≥}/{Y≤} ... Inequality {Y>
f(x)}/{Y<f(x)}/{Y≥f(x)}/{Y≤f(x)} graphing
• {X>}/{X<}/{X≥}/{X≤} ... Inequality {X>
f(y)}/{X<f(y)}/{X≥f(y)}/{X≤f(y)} graphing
