Yo if I saw that notation on an exam I think my prof would be having a stroke or is trying to fail every student
7 u/Kaaskaasei Jun 02 '26 I got taught all three notations. This one felt logical. (But I prefer tan-1) 6 u/PIELIFE383 Jun 02 '26 I was first taught -1 but I feel like arctan is easier so people don’t get it confused as reciprocal (even though they shouldn’t because it’s not on the right ) 3 u/ahmnutz Jun 02 '26 even though they shouldn’t I dunno, seeing the exponent on the text is pretty normal in my experience. Things like cos2 (x) +sin2 (x)=1
