defining the (cw/ccw) in radians (pos/neg)

Question

are there any negative radians?

    **deg°  0.0  32.9       /-32.9
    **rad*  0.0   0.5742133 / -0.5742133

Answer 1

We usually associate $x$ degrees to an anticlockwise rotation if $x$ is positive and to a clockwise rotation if $x$ is negative. The same applies to radians, with the relation $180$ degrees equals $\pi$ radians.
