Determining the Intersect of Straight Lines or Planes (Not available
with the fx-CG50 AU, fx-CG20 AU)
You can determine the combinations below for intersection points and intersecting lines.
Line-line ... Point of intersection
Line-plane ... Point of intersection
Plane-plane ... Line of intersection
To determine a line-line point of intersection
1. Use the Line template to register the two straight line functions below.
Straight line 1: P1=0,0,0
P2=1,1,1
Straight line 2: P1=1,1,0
P2=2,2,2
2. Press 6(DRAW) to draw the 3D graph.
3. Press !5(G-SOLVE)2(INTSECT).
This displays the coordinates of the intersect. (In the case of plane-plane, the function of
the line of intersection will appear on the display.)
4. To delete the intersect display, press J.
The message “NOT FOUND” will appear if the two 3D graphs do not intersect.
The message “INFINITE” will appear if the two 3D graphs are identical.
When there are three straight lines or planes, you can change how they are combined by
pressing 1(Next)/2(Back).
To find intersection, you must use the Line template or Plane template to draw two or more
3D graphs.
