WebMar 14, 2024 · Cartesian coordinates (rectangular) provide the simplest orthogonal rectangular coordinate system. The unit vectors specifying the direction along the three orthogonal axes are taken to be (ˆi, ˆj, ˆk). In cartesian coordinates scalar and vector functions are written as ϕ = ϕ(x, y, z) r = xˆi + yˆj + zˆk

In spherical coordinates, the unit vectors depend on the position. Specifically, they are chosen to depend on the colatitude and azimuth angles. So, r = r …

Web2 days ago · In another attempt, I have used polar coordinates (r, phi) with the usual transformation from Cartesian coordinates. With a fixed r, phi varies from the minimum angle to the maximum angle by increments of e.g. 1/r and selects the pixels of the arc. The result is slightly better than the previous algorithm, but some rows are longer than rows ... WebApr 2, 2024 · It returns the Cartesian coordinates ‘xv’, ‘yv’, and ‘zv’ that are vectors because φ is the vector ‘phiv’. Those are then transformed into the longitude coordinates ‘lv’ , and corresponding latitude coordinates ‘bv’ , in the ‘ct2sp’ call immediately after that, both of them being vectors as well, because their ...

WebEither r or rho is used to refer to the radial coordinate and either phi or theta to the azimuthal coordinates. Arfken (1985), for instance, uses (rho,phi,z), while Beyer (1987) uses (r,theta,z). In this work, the notation (r,theta,z) is …

Webρ = x 2 + y 2 = r sin θ. using Pythagoras' Theorem gives. r = ρ 2 + z 2 = x 2 + y 2 + z 2. Next take z = r cos θ which gives. θ = arccos ( z r). Both of these agree with what I have found on wikipedia, however I can't understand how the last coordinate ϕ is reached.
