The words for sine and cosine derive from the sanskrit jiva (meaning bowstring, i.e., the chord of a circle)[1]. Sine and cosine were respectively jya and koti-jya, which got transcribed into arabic without the vowel (where it meant nothing). They then pronounced the vowel in the wrong place, calling it jeb (which meant pocket or fold in arabic)[2]. Then this wrong word got translated into latin as sinus (fold), and hence we have sine and cosine!

Arabic is also popular, particularly in maths.
Edit: I think almost every word with "ph" in it is from Greek and "th" in languages other than English.
- azimuth
- zenith
- nadir
Also some chemistry terms, again just from top of brain, might be wrong: - alchemy
- elixir
- arsenic
- alkaliThe difference between an apex and a zenith is that an apex exists as a point in space, while a zenith is a direction, with no fixed point which may be said to be "the" zenith. There are other differences given that apex has a few related meanings, but this is the main one.
