A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if you rotate the system, it doesn’t look different. For instance, if a sphere of radius R is uniformly charged with charge density …In lieu of x and y, the cylindrical system uses ρ, the distance measured from the closest point on the z axis, and ϕ, the angle measured in a plane of constant z, beginning at the + x axis ( ϕ = 0) with ϕ increasing toward the + y direction.Starting with polar coordinates, we can follow this same process to create a new three-dimensional coordinate system, called the cylindrical coordinate system.

The calculus of higher order tensors can also be cast in terms of these coordinates.Suggested background. Cylindrical coordinates are a simple extension of the two-dimensional polar coordinates to three dimensions. Recall that the position of a point in the plane can be described using polar coordinates (r, θ) ( r, θ). The polar coordinate r r is the distance of the point from the origin. The polar coordinate θ θ is the ...When we convert to cylindrical coordinates, the z-coordinate does not change.
