atan2vx
atan2vx is a naming variant for a two-argument arctangent function used to compute the heading of a two-dimensional vector from its x and y components. In practice it is equivalent to the standard atan2 function, typically implemented as θ = atan2(vy, vx), where vy is the vector’s y component and vx its x component. The name emphasizes inputs labeled vx and vy, which can align with velocity components or coordinate axes in programming contexts.
Definition and range: Given real numbers vx and vy, atan2vx returns the angle θ in radians such
Edge cases and interpretation: If both vx and vy are zero, the angle is undefined in pure
Applications and relationship to other functions: atan2vx is commonly used in robotics, computer graphics, navigation, and
