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.
• 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
k Calculating the Point of Intersection of Two Graphs
Use the following procedure to calculate the point of intersection of two graphs.
1. Draw the graphs.
2. Press !5(G-SLV) 5(ISCT). When there are three or more graphs, the selection cursor
( k) appears at the lowest numbered graph.
3. Press f and c to move the cursor to the graph you want to select.
4. Press w to select the first graph, which changes the shape of the cursor from k to
.
5. Press f and c to move the cursor to the second graph.
6. Press w to calculate the point of intersection for the two graphs.
When an analysis produces multiple values, press e to calculate the next value.
Pressing d returns to the previous value.
Example Graph the two functions shown below, and determine the point of
intersection between Y1 and Y2.
Y1 =
x + 1, Y2 = x
