WebJul 21, 2024 · Rotation matrices are orthogonal matrices, i.e., R − 1 = R T. An orthogonal n-by-n matrix has n ( n − 1) / 2 independent parameters ( see here for an elegant proof ), which in our case is 6 parameters. Linear algebra tells us that a 6-component vector can be represented in terms of 6 linearly independent vectors.
