###### These functions are effective in exploring 3D Graphs geometrically.

##### 1. Viewing from various directions

###### ①Zoom in and zoom out ②Rotation vertically and horizontally ③Cross section ④X-axis, Y-axis, Z-axis view.

These functions are effective in exploring 3D graphs geometrically.

##### 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).
