curprev 04:3804:38, 7 November 2021‎ 68.181.64.16 talk‎ 9,831 bytes −2‎ I improved the clarity. Previously, the text talked about "coordinate-z plane", but it is unclear what this means. There are xy, xz and yz coordinate planes, but there is no such thing as "coordinate-z plane". What is meant here is "z=0 plane". The same formulation was already correctly used in the previous paragraph, so this change has the added benefit of keeping the terminology consistent. [I am a professional mathematician.] undo

Often derivatives are denoted as subscript indices, but only after a comma. The convention is called comma derivative. (http://mathworld.wolfram.com/CommaDerivative.html) I beleive this was what the original author intended. undo
