WebGrad, Div and Curl in Cylindrical and Spherical Coordinates In applications, we often use coordinates other than Cartesian coordinates. It is important to remember that expressions for the operations of vector analysis are different in diﬀerent coordinates. Here we give explicit formulae for cylindrical and spherical coordinates. WebSpherical Polar Coordinate. In spherical polar coordinates, the coordinates are r,θ,φ, where r is the distance from the origin, θ is the angle from the polar direction (on the Earth, colatitude, which is 90°- latitude), and φ the azimuthal angle (longitude).

This becomes obvious when you write down r ^ in cartesian coordinates: r ^ = sin θ cos ϕ x ^ + sin θ sin ϕ y ^ + cos θ z ^ Thus, to each pair ( θ, ϕ) you have a different versor r ^, which has norm ne and points outwards the sphere.
