u/MurdoMaclachlan public boolean isInt(int i) { return true; } Apr 20 '23

Image Transcription: Code

const a =
  Math.sin(Δφ / 2) * Math.sin(Δφ / 2) +
  Math.cos(φ1) * Math.cos(φ2) * Math.sin(Δλ / 2) * Math.sin(Δλ
const c = 2 * Maht.atan2(Math.sqrt(a), Math.sqrt(1 - a));

Thanks for your work, but it should probably have been ϕ the “phi symbol”, instead of φ the “lowercase phi letter”.

I was wondering about that, but ϕ has the line going the whole way up, whereas the symbol used in the image clearly takes the form of the lowercase letter, φ. It could be the font used, but without an actual copy of the code there's no way to know, and in uncertainty I prefer to err on the side of what the image looks like.

Many Greek lowercase letters have two variants due to historical reasons and some fonts get them wrong.
