What are "tan" and "atan"? - Mathematics Stack Exchange

WebPlease Note atan is not broken. arctan or tan inverse is only a function between -PI/2 and PI/2. It repeats this pattern but then it isn't a function which is a problem for a computer as it doesn't handle multiple answers. This is the same for asin between -PI/2 and PI/2 and acos between 0 and PI. These are the simplest ranges for a function to ...
