Vector Dot Product Demo by raphnano

This example dynamically demonstrates the calculation and geometric interpretation of the dot product between two vectors. It involves core math concepts like vector dot product, vector magnitude, cosine of angle formula, linear equations, and matrix operations. GeoGebra commands used include Vector and Angle to construct vectors u, v, w_1, A, and angles α, a, β. Suitable for high school and above students to visualize vector dot product, linear algebra, and optimization problems.
