Matrix Rotation Demonstration
Loading the math board and drawing, please wait…
This example demonstrates how to use trigonometric matrices for 2D geometric rotation transformations. It involves core mathematical concepts such as matrix operations, trigonometric functions, rotational transformations, and analytical geometry. Key GeoGebra commands/objects used include objects: b, l1, I1, m1, A, B, c. Suitable for high school and above students learning the application of matrices in geometric transformations, as well as for teaching demonstrations in calculus and linear algebra.
