Partial Derivative Demo

This example demonstrates the geometric interpretation of partial derivatives by interactively showing the tangent plane at a point on a function and its relationship with partial derivatives. Key math concepts include partial derivatives, vectors, translation, geometric mean, and logarithmic functions. It uses GeoGebra commands like IntersectPath and objects such as a, z_1, eq1, eq2, b, f, A, p, eq3. Suitable for university-level calculus and differential geometry courses or self-study to visualize abstract concepts.
