Is there a Latex symbol to represent the inverse angle of a complex number? Since, from what i see, this isn't very well known, I'll post a picture of my math book which uses it below (Engineering Mathematics - Stroud). Thanks.

    You can use the information provided in How to draw a partial or incomplete box around one or more words within a paragraph to create your own \invangleb{120} and \invanglet{135} (say). – Werner Feb 22 '17 at 0:58
  • How can a number have an inverse angle? (Off-topic, obviously.) Does 1 have an inverse angle, let alone i? – cfr Feb 22 '17 at 2:55
  • @cfr It's just the negative angle. Negative 135 = 360 -135 = 225. – Nikos Feb 22 '17 at 9:53
  • I know what an inverse angle is. I just doubt that numbers can have them. I doubly doubt that complex numbers can. – cfr Feb 22 '17 at 23:36
