The inverse of addition is subtraction and vice versa. The inverse of multiplication is division and vice versa.
Lower-case arcsin(x) is all possible numbers or angles whose sine is x. The same convention applies to the other five functions. (See Notation, below, for other ways of writing the inverse relation and the inverse function.) Now all we need is a rule for picking the principal values of all the inverse trig functions.
