12-2 Using Graph-to-Table
u u u u u
To store graph pointer coordinates in a table
• If the Derivative item in the set up screen is set to “ On”, the derivative at the
location of the trace pointer is also stored in the table.
Example To store the points of intersection and the coordinates for the
following graphs where X = 0:
Y1 = x 2 – 3 Y2 = – x + 2
Use the following View Window parameters.
Xmin = –5
Ymin = –10
Xmax = 5 Ymax = 10
Xscale = 1 Yscale = 2
1. Input the two functions.
2. Press 6 (DRAW) (or w) to draw the
graph in the left half of the screen.
3. Press 1 (Trace) and then use d to move the pointer to the first intersection.
4. Press w to store the coordinates of
the pointer location in the table on the
right side of the screen.
5. Use e to move the pointer to the point
where X = 0 and then press w.
Next, move the pointer to the next
intersection and press w again.
