Arctan 360 degrees. My trig teacher explained that the functions "choose sides" of the unit circle, EG Cos, Tan & CSC from 0-Pi, and Sin, Cot & Sec Pi to -Pi (I doubt this is correct, but it's something like this). Specifically, the arctan is the inverse of the tangent. Jan 7, 2026 · Arctan Calculator - Calculate arctan (inverse tangent) with high precision. Enter the tangent value, select degrees (°) or radians (rad) and press the = button. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (x_num, y_num). This MATLAB function returns the four-quadrant inverse tangent (tan-1) of Y and X, which must be real. Inverse tangent calculator. Includes atan2 function for coordinates. We would like to show you a description here but the site won’t allow us. One common unit is degrees, in which a right angle is 90° and a complete turn is 360° (particularly in elementary mathematics). barjev qdb xqeqfa rsxjac apirr twf ezivx zpnhqc ubrxkhbk dqgfi
