Please explain, am using to study for a test
ll. Suppose you made two consecutive counterclockwise rotations of the -y - z coordinate system. The first is a rotation about the -axis by angle that leads to -y - coordinate system. The second is a rotation about the y/-axis by an angle that leads to -y-.
a) Make two sketches that shows these successive rotations.
b) Find the two set of equations for these two rotations and write these equations using matrices.
