WebFour-Quadrant Inverse Tangent. The four-quadrant inverse tangent, atan2 (Y,X), returns values in the closed interval [–π, π] based on the values of Y and X, as shown in the graphic. In contrast, atan (Y/X) returns results … WebThe derivation goes as follows: If (x, y) = (r cos θ, r sin θ), then tan (θ/2) = y / (r + x). It follows that. atan2 ⁡ ( y , x ) = θ = 2 θ / 2 = 2 arctan ⁡ y x 2 + y 2 + x . {\displaystyle …
