For rotation by an angl
e θ clockwise about the origin, the functional form is x' = xcosθ + ysinθ and y' = − xsinθ + ycosθ. Written in matrix form, this becomes:
Similarly, for a rotation counter-clockwise about the origin, the functional form is x' = xcosθ − ysinθ and y' = xsinθ + ycosθ and the matrix form is:
