Inverse Cosine Function

Owning Palette: Trigonometric Functions

Requires: Base Development System

Computes the arccosine of x.

If x is not complex and is less than –1 or greater than 1, the result is NaN. The connector pane displays the default data types for this polymorphic function.

	x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.
	arccos(x) is of the same numeric representation as x. When x is of the form x = a + bi, that is, when x is complex, the following equation defines arccos(x):
