Coordinate systems/Derivation of formulas

The purpose of this resource is to carefully examine the Wikipedia article Del in cylindrical and spherical coordinates for accuracy.

The identities are reproduced below, and contributors are encouraged to either:

  1. Verify the identity and place its reference using a five em padding after the equation: {{pad|5em}}verified<ref>reference</ref>
  2. Contribute to Wikiveristy by linking the title to a discussion and/or proof. Just click the redlink and start the page.

If you just came in from Wikipedia, the rules about treating each other with respect and obeying copyright laws remain more or less the same as on Wikipedia, but the definition of what constitutes an acceptable article is a lot looser. Here we call them "resources". Welcome to the wacky world of Wikiversity, where anything goes.

Transformations between coordinates

  1. w:Cartesian coordinates (x, y, z)
  2. w:Cylindrical coordinates (ρ, ϕ, z)
  3. w:Spherical coordinates (r, θ, ϕ)
  4. w:Parabolic cylindrical coordinates (σ, τ, z)
