Explore the relationship parallel, orthogonal, etc. Expression of the intersection line or the coordinates of intersection. Explore the coordinates on the surface of 3D graphs all kinds by using the cursor keys to move the trace pointer.Įxplore the intersection coordinates, line between 3D graphs line and line, line and plane, plane and plane. These functions are effective in exploring 3D graphs geometrically. Recognize combinations of 3D graphs and interactive relationships between two or three graphs mathematically. This feature promotes mathematical understanding of 3D graphs and helps in learning solid figures. All you need are the fx-9860GII SD / fx-9860GII and a data projectorįor example, students can use either Graph, Equation, or Matrix function to solve the simultaneous equations below. Students can cultivate mathematical thinking through Graph functions operated by themselves. Graphing calculators have a variety of functions covering from primary to higher education. Use the G-Solve feature to easily solve problems involving intersections, roots, and integration.
