How do I write sin(x) where the x-axis is a function itself. For example, I want to write sin(x) along a half circle. I need to "wrap" the function, similar to "De Broglie wavelength" in image below.
More specifically, I want to write f1 = 0.1*sin(x) the where the x-axis is f2 =...
You would get that equation if you only accounted for the OPD inside resonator. There is also a little OPD outside you must subtract. See...
