Just type matrix elements and click the button. and thus each nonzero vector of R 2 is an eigenvector. 5 If it's a 2D rotation matrix, then it equals R ( θ) = ( cos θ − sin θ sin θ cos θ) where θ is the angle you are looking for. Then R_theta=[costheta -sintheta; sintheta costheta], (1) so v^'=R_thetav_0. The fixed point is called the center of rotation .The amount of rotation is called the angle of rotation and it is measured in degrees. Due to the periodicity of the cosine function though, you won't know the sign of θ (i.e., whether it is clockwise or anticlockwise).
