Abstract: The total yaw angle is the angle between the velocity and symmetry axis of a projectile. The total yaw angle can be related to the pitch and yaw angles through a widely available expression. Recently, we needed the total yaw angle and attempted to derive that expression as an exercise. We obtained a different, and seemingly contradictory, expression instead. The 2 expressions are actually equivalent, which we demonstrate.
