🧄How the Cross Product Relates to the Sine of an Angle
The demo application acts as a practical illustration and verification tool for Lagrange's Identity. While the detailed analysis proves the identity algebraically, the demo provides a direct, hands-on experience. It allows you to quickly input any two vectors and visually confirm that the calculated squared magnitude of their cross product is equal to the product of their individual squared magnitudes minus the square of their dot product. This functionality bridges the gap between abstract algebraic proof and concrete numerical application, solidifying your understanding of the fundamental relationship between these vector operations.
