radianAngle# = ACOS (expr)
Description edit
Returns the arccosine of expr
in radians. In other words, if expr
represents the cosine of some angle, then ACOS(expr)
returns the angle. The returned angle will be in the range of 0 to π radians (which corresponds to 0 to 180 degrees). ACOS
always returns a double-precision result.
