Summary
Vehicle attitude is typically quantified by a DCM, a quaternion, or a triplet of Euler angles. I discuss how each of these objects changes with attitude by deriving the well-known time derivative of each. That requires the concept of angular velocity, which I discuss in detail. I end the chapter by describing why time derivatives of Euler angles cause so much confusion to many practitioners.
