k Coordinate Rounding
This function rounds off coordinate values displayed by Trace.
1. From the Main Menu, enter the Graph mode.
2. Draw the graph.
3. Press !2(ZOOM) 6( g) 3(ROUND). This causes
the V-Window settings to be changed automatically
in accordance with the Rnd value.
4. Press !1(TRACE), and then use the cursor keys
to move the pointer along the graph. The coordinates
that now appear are rounded.
k Analyzing Graphs (G-SOLVE Menu)
Pressing !5(G-SOLVE) displays a function menu that contains functions you can use to
analyze the currently displayed graph and obtain the following information.
!5(G-SOLVE)1(ROOT) ... Root of the graph
2(MAX) ... Maximum value of the graph
3(MIN) ... Minimum value of the graph
4(Y-ICEPT) ...
y-intercept of the graph
5(INTSECT) ... Intersection of two graphs
6(g)1(Y-CAL) ...
y-coordinate for a given x-coordinate
6(g)2(X-CAL) ...
x-coordinate for a given y-coordinate
6(g)3(∫d
x)1(∫dx) ... Integration value for a specified range
6(g)3(∫d
x)2(ROOT) ... Integration value between the two or more of
the graph’s roots
6(g)3(∫d
x)3(INTSECT) ... Integration value between the two or more
intersections of two graphs
6(g)3(∫d
x)4(MIXED) ... Integration value between a graph root, a
point of intersection of two graphs, or any
x-coordinate
• Either of the following can cause poor accuracy or even make it impossible to obtain
solutions.
- When the graph of the solution obtained is a point of tangency with the
x-axis
- When a solution is an inflection point
