Determinant of rotation matrix
The trace of a rotation matrix is equal to the sum of its eigenvalues. For n = 2, a rotation by angle θ has trace 2 cos θ. For n = 3, a rotation around any axis by angle θ has trace 1 + 2 cos θ. For n = 4, and the trace is 2 (cos θ + cos φ), which becomes 4 cos θ for an isoclinic rotation.

WebThe matrix transformation associated to A is the transformation. T : R n −→ R m deBnedby T ( x )= Ax . This is the transformation that takes a vector x in R n to the vector Ax in R m . If A has n columns, then it only makes sense to multiply A by vectors with n entries. This is why the domain of T ( x )= Ax is R n .
