Note
• The outline of the cross section of a 3D graph sliced with a plane is highlighted using the opposite
color of the color specified by
in the forefront plane.
• When a planar graph is sliced, the outer border of the planar graph is highlighted if the planar graph
overlaps the plane being used for slicing.
To view a cross section from a particular direction
While a cross section is displayed, perform one of the operations below.
To do this:
Display the view along the positive x -axis
Display the view along the positive y -axis
Display the view along the positive z -axis
Return the view direction to its original view
To move the cross section of a 3D graph
Press U or D to move a cross section on the applicable axis. You can also specify a location on a cross
section by directly inputting a coordinate value on the applicable axis.
Determining the Intersect of Straight Lines or Planes (fx-CG100 only)
You can use the operations below to determine the intersect of two lines, the intersect of a line and a plane, or
the intersect of two planes. This operation can be performed on lines and/or planes drawn using a template.
To graph the lines X − 1
Example 1:
intersect
1. Use Function tab templates to store the equations of the two lines.
2. Press > to draw the graph.
3. Select T > [Graph Solve] > [Intersection].
• This displays the intersect of the two lines. The coordinates
of the intersect are shown in the lower left corner of the
display.
Example 2: To graph the two planes X+Z=0 and X+Y=0 and determine their intersect
1. Use Function tab templates to store the equations of the two planes.
