Spherical Coordinates Demo by matheagle

This example demonstrates the representation and transformation of points in spherical coordinate systems. It involves core mathematical concepts such as spherical coordinates, 3D spatial geometry, and trigonometric relationships. Construction highlights include using the Surface command to plot a sphere, Segment and Angle commands for geometric relations, and the If command for conditional logic. Key objects used are ρ_0, r_1, ϕ_0, θ_0, r, b, P, a, c, ϕ, Q, d, A, B, e, f, g, h, θ, α, i, text1, text2, text3. Suitable for high school and above students learning spatial coordinate transformations and 3D geometric constructions.
