How to find the angle and direction of a rotation matrix in 2D?
If I have a rotation matrix:
how can I get the angle and the direction of it?
If I do:
which are two different angles, 135 and -44 in degrees, how do I know which one is the answer and what direction the rotation is happening?
I couldn't find anything on the internet, so any links explaining how to get the angle and the direction would be grateful.
