Difference between Spherical coordinate system and Spiral

Spherical coordinate system vs. Spiral

In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a given point in space is specified by three numbers, (r, θ, φ): the radial distance of the radial line r connecting the point to the fixed point of origin (which is located on a fixed polar axis, or zenith direction axis, or z-axis); the polar angle θ of the radial line r; and the azimuthal angle φ of the radial line r. The polar angle θ is measured between the z-axis and the radial line r. The azimuthal angle φ is measured between the orthogonal projection of the radial line r onto the reference x-y-planewhich is orthogonal to the z-axis and passes through the fixed point of originand either of the fixed x-axis or y-axis, both of which are orthogonal to the z-axis and to each other. In mathematics, a spiral is a curve which emanates from a point, moving farther away as it revolves around the point.
