>From a quick review of Cajori's book on mathematical notation, the first citation of the full set of "absolutely standard" notations (sin, cos, tan, sec, csc, cot) is from 1890. There were are a lot of variations and strange symbols before this. As Devon points out, there is no uniform standardization of inverse trigonometric functions, even tody.
