Non-differentiable Surface
Loading the math board and drawing, please wait…
This example demonstrates the geometric shape and properties of a non-differentiable surface. Key math concepts include surfaces, non-differentiability in calculus, and the continuity of geometric forms. Construction highlights involve using the GeoGebra command 'Object: f' to define the function or surface. Suitable for high school and above students studying calculus and analytical geometry to understand the relationship between function differentiability and geometric meaning.
GeoGebra Commands & Parameters
f(x, y) = (x^(2) * y / (x^(2) + y^(2)))
AI Drawing Prompt Reference
Draw a 3D surface defined by the function f(x, y) = (x^2 * y) / (x^2 + y^2). The surface should show a smooth continuous shape away from the origin, but near the origin it exhibits non-differentiability, meaning the surface has a sharp fold or discontinuity in slope as different paths approach the origin. Emphasize the overall undulating form in three-dimensional space, with a clear visual highlight of the singular behavior at the origin. Use a grid or color shading to illustrate the surface's continuity and the abrupt change at that point.
