Casimir Effect, what does (x,θ) mean?

  1. Jun 1, 2014 #1
    Hello look at (3.24). Above it, it states "We make the same switch to polar coordinates (x, φ) in the (x, y) plane, and substitute y ≡

    Should (x, φ) be (r, φ)? Is this a typo?

    Thank you.

    Note he says the same switch. That's a clue, isn't it, that earlier in the paper he did the same thing? :wink:

    I believe you'll find that in both places what he did was change to polar coordinates (x, y) → (r, φ) and then call the radial coordinate x.
