WebJan 14, 2024 · The atan function is not the true inverse of tan but is limited per definitionem to the range [-pi; pi] to make it a unique function. But if you don't use numeric inline evaluation when calculating t, symbolic solver "remembers" where it came from - at least as long as ar rational and not given as float value. WebATAN2 function Description. Arc tangent of two numbers, or four-quadrant inverse tangent. ATAN2(y, x) returns the arc tangent of the two numbers x and y. It is similar to calculating the arc tangent of y / x, except that the signs of both arguments are used to determine …

WebJan 31, 2014 · atan2(vector.y, vector.x) = the angle between the vector and the X axis. But I wanted to know how to get the angle between two vectors using atan2. So I came across this solution: atan2(vector1.y - vector2.y, vector1.x - vector2.x) My question is very simple: Will the two following formulas produce the same number? WebOct 17, 2012 · atan2b (y,x) = pi+atan2 (-y,-x) where atan2b now outputs between 0 and 2π, since the calculation atan2 (-y,-x) differs from atan2 (y,x) by an angle of π (mod 2π) If you're going to take this approach, don't calculate -atan2b (y,x); instead calculate atan2b (-y,x), (equivalent mod 2π) so that the range of output angles is left unchanged.
