Oblate spheroidal coordinates are a three-dimensional orthogonal coordinate system that results from rotating the two-dimensional elliptic coordinate system about the non-focal axis of the ellipse, i.e., the symmetry axis that separates the foci. Thus, the two foci are transformed into a ring of radius See more The most common definition of oblate spheroidal coordinates $${\displaystyle (\mu ,\nu ,\varphi )}$$ is where $${\displaystyle \mu }$$ is a nonnegative real number and the angle Coordinate surfaces See more An alternative and geometrically intuitive set of oblate spheroidal coordinates (σ, τ, φ) are sometimes used, where σ = cosh μ and τ = See more • MathWorld description of oblate spheroidal coordinates See more • Ellipsoidal coordinates (geodesy) See more No angles convention • Morse PM, Feshbach H (1953).
