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.

Comment
When I first saw the Casio fx-CG50 in action I was amazed by the color and the power at my fingertips. My students fell in love with the simplicity of its menu driven icons. They commented that it was like using a smartphone. As a teacher I look for technology that will support what I am doing in class and not complicate my lessons. The fx-CG50 replaced my need for complicated button pushing instructions and allowed me to focus on teaching mathematics at a deeper level. My lessons could focus on understanding the math behind the solution on the screen. I can explore mathematics like addition, geometry, statistics, probability, calculus, 3D graphing and beyond. The fx-CG50’s built in functions allow for use in science classes. Students can convert between units and use physics constants in calculations. There is even a built in high resolution periodic table of elements. It is the one essential tool in my S.T.E.M toolbox.
