Question

This transformation is called a rotation with shear. Can you see why it might be called that? Let’s investigate more. Find the determinant of the rotation matrix. Det R = _____ which matches the determinant for our other______. Find the product of the matrix and it’s transpose: R • Rt is______.

Answer 1

Answer:

Det R = 1 which matches the determinant for our other NOT ROTATION MATRICES. Find the product of the matrix and it’s transpose: R • Rt is the identity matrix.
