Web2 de fev. de 2016 · Accepted Answer. In order to determine if the angle between two vectors is positive or not, there would have to be a reference normal plane vector (vn). If so, yes you can. There is a way to check if the angle between those two vectors should be negative. First take the cross product of the two vectors (v1 x v2) to get the normal of the plane (v3). Web27 de jan. de 2024 · $\begingroup$ Yes, tangent is negative in quadrant IV and II, but the range for arctan is limited to $\frac{-\pi}{2}\le{y}\le\frac{\pi}{2}$ so our angle cannot lie in quadrant II. It must lie in either quadrant I or IV. And since it is negative, it must lie in quadrant IV. $\endgroup$ –
