(also spherical polar coordinates)
Three coordinates that define the location of a point in three-dimensional space. They are the length of its radius vector r, the angle θ between the vertical plane containing this vector and the x-axis, and the angle φ between this vector and the horizontal x-y plane.
- Usually written (r, θ, φ)
