This example demonstrates the distribution and variation phenomena of vector fields in 3D space. Core mathematical concepts include vectors, 3D coordinate systems, and vector fields in calculus. Construction highlights involve Geogebra commands/objects like Sequence, Textfield, Element, spacing, extent, grid, xcomp/ycomp/zcomp, scale, vectors, InputBoxes, text elements, parameters (a), axes, vector components (u_1-u_4), listvectordirection, Selectedvector, and buttons. Suitable for university students and teachers in mathematics, physics, and related fields for teaching demonstrations and conceptual understanding.

AI Drawing Prompt Reference

Visualize a 3D vector field, showing the distribution and variation of vectors in space. The graph includes a 3D coordinate system grid and a series of vectors, each starting from a grid point, with direction and length representing the vector field's direction and magnitude at that point. The direction and magnitude of the vectors vary with location, demonstrating the distribution and variation of the vector field. Use input boxes to adjust the calculation formulas for the x-component, y-component, and z-component of the vectors and update the display of vectors in the graph in real-time. Additionally, you can select specific vectors for highlighting to observe and analyze the characteristics of the vector field more clearly.
