k Calculating the Root
Description
This feature provides a number of different methods for analyzing graphs.
Set Up
1. From the Main Menu, enter the GRAPH mode.
2. Draw the graphs.
Execution
3. Select the analysis function.
!5 (G-SLV)1 (ROOT) ... Calculation of root
2 (MAX) ... Local maximum value
3 (MIN) ... Local minimum value
4 (Y-ICPT) ...
y -intercept
5 (ISCT) ... Intersection of two graphs
6 (g )1 (Y-CAL) ...
y -coordinate for given x -coordinate
6 (g )2 (X-CAL) ...
x -coordinate for given y -coordinate
6 (g )3 ( ∫
dx ) ... Integral value for a given range
4. When there are multiple graphs on the screen, the selection cursor (k ) is located at the
lowest numbered graph. Press f and c to move the cursor to the graph you want to
select.
5. Press w to select the graph where the cursor is located and display the value
produced by the analysis.
When an analysis produces multiple values, press e to calculate the next value.
Pressing d returns to the previous value.
