Learn 3D Graphs more deeply using Explore feature
It’s difficult to understand 3D graphs used in textbooks.
The 3D Graph feature of the fx-CG50 makes it easy to draw and explore 3D graphs. This feature promotes mathematical understanding of 3D graphs and helps in learning solid figures.
1. Draw and display 3D Graph
3D graphs can be drawn in various ways.
1) Using templates
It’s easy to draw 3D graphs using templates. (*An industry-first feature)
2) Z= graph
3) Parametric graphs
4) Rotating body graphs (① around X-Axis, ② around Y-Axis) *An industry-first feature
Rotating body graphs can be drawn in two ways (rotating around X-Axis or Y-Axis).
2. Draw and display up to three 3D graphs
Recognize combinations of 3D graphs and interactive relationships between two or three graphs mathematically.

2) Tracing of graphs *An industry-first feature
Explore the coordinates on the surface of 3D graphs (all kinds) by using the cursor keys to move the trace pointer.
3) Intersection between graphs *An industry-first feature
Explore the intersection (coordinates, line) between 3D graphs (line and line, line and plane, plane and plane).
Expression of the intersection line or the coordinates of intersection
4) Relation between graphs *An industry-first feature
Explore the relationship (parallel, orthogonal, etc.) between 3D graphs (line and line, line and plane, plane and plane).

1. Z= graph
2. Parametric graphs
3. Rotating body graphs
Example 1
Examine intersections between lines, planes and spheres.
Effective learning with 3D Graph
1. Draw and display 3D Graph
Students get the possibility to visualize the most important intersections between lines, planes and spheres: The intersection point, line or circle. This can be very helpful for them to develop solution strategies.
Additionally different input methods are used in all these examples.
Definition by vector, definition by equation.
Definition by vector, definition by equation.
Students can view graphs from various angles, and explore the intersection between 2 objects visually by themselves.
Example 2
Examine the relationship between lines and planes and their intersections.
Teachers and pupils can study the relationship between lines and planes and can examine their intersections.
Intersection : Intersection point, intersection line or Not Found, etc.
Relation : Intersection, Parallel, Orthogonal, or Skewed lines etc.
