Vectors and Planes vs Beautiful Functions

Vectors and Planes App helps visualize and understand 3D linear and quadric structures and their intersections. List of linear structures and combinations: 1. Two vector combination. 2. Plane. 3. Line and plane combination. 4. Two plane combination. 5. Three plane combination. Current list of quadric structures: 1. Two sphere combination. 2. Standard ellipsoid. 3. Ellipsoid in a form of positive-definite matrix. 4. Standard cone. 5. Cone in a form of indefinite matrix. 6. 1-sheet hyperboloid. 7. 1-sheet hyperboloid in a form of indefinite matrix. 8. 2-sheet hyperboloid. 9. 2-sheet hyperboloid in a form of indefinite matrix. 10. Standard cylinder. 11. Cylinder in a form of positive-semidefinite matrix. 12. Hyperbolic paraboloid. 13. Elliptic paraboloid. Current list of combinations of quadric and linear structures: 1. Matrix ellipsoid and line. 2. Standard ellipsoid and plane. 3. Matrix ellipsoid and plane. 4. Matrix cone and line. 5. Standard cone and plane. 6. 1-sheet hyperboloid in matrix form and line. 7. 2-sheet hyperboloid in matrix form and line. 8. Matrix cylinder and line. 9. Elliptic paraboloid and line. 10. Hyperbolic paraboloid and line. Interactive 3D graphs are provided for all of the above. Step by step calculation algorithms are provided for all intersection point sets. Many of the algorithms are based on Linear Algebra concepts. Those, in turn, are explained in our “Matrix Solver Step by Step” app. Version 10 was completely redesigned. Developers hope to get feedback from users at graphmath@aol.com.

Functions make sense when you can see them. Beautiful Functions turns every change in an equation into an immediate change on the graph. Move a slider, watch the curve respond, and understand what each parameter actually does - before memorizing a rule or solving an exercise. NOT JUST A GRAPHING CALCULATOR This is a visual learning environment designed to show how functions work. Watch a line cross a parabola twice, become tangent, then miss it completely. See a function reflect into its inverse. Switch the same parabola between Standard, Vertex, and Factored forms. Change amplitude, frequency, and phase, and watch every wave transform. EXPLORE WITH PURPOSE Use roots, intercepts, vertices, symmetry, extrema, inflection points, and asymptotes as visual guides instead of isolated definitions. Collapse the graph when you want to focus on an explanation, then bring it back to test your intuition. START FREE Start with Linear, Quadratic, Cubic, and Logarithmic Functions.
