A concept for functional graph using a visible image without any calculation is provided to offer mathematics education based on understanding by making a student experience a process for producing a formula with concrete proof using a cube visualizing a principle. A specific line, a specific face, and a specific cube are introduced as a minimum unit particle for proving the mathematical principle and are visualized. The basic formula up to a 3-order function such as a factorization formula and a multiplication formula is proved by discriminating minimized unit figures into the particles of a positive and negative number. Agreement with a graphic concept of the function is displayed as the minimum unit shapes represent each property in each space separated by an axis. |
