Find the inverse of the rotation matrix
cos(theta) -sin(theta)
sin(theta) cos(theta)
I have no problems finding the inverse of a standard 2x2 matrix, however I am confused by the trig functions.
I guess the determanent would be 2cos(theta) and I would end up with
1/2cos(theta)*(the above 2x2 matrix)
Any assistance is greatly appreciated.
