Function Analysis

kCalculating 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.
