The Euler angle parameterization Rotations

Feb 08, 2021  The most popular representation of a rotation tensor is based on the use of three Euler angles. Early adopters include Lagrange, who used the newly defined angles in the late 1700s to parameterize the rotations of spinning tops and the Moon [1, 2], and Bryan, who used a set of Euler angles to parameterize the yaw, pitch, and roll of an airplane in the early 1900s [].
