# Euler Angle Results

Orientation of one coordinate system relative to another is defined by a sequence of three successive rotations. The three Euler angles define one such body-fixed rotation sequence.

`Ψ`,

`Θ`, and

`Φ`in Motion Analysis results are the sequence of Z-, X-, and Z-axis rotation angles measured about the body of the rotating coordinate system.
