Question

does anyone know how to rotate a single point 166 degrees?

Answer 1

if coordinates are (x,y), to rotate 166 degrees use the following matrix operation:

|cos(166) sin(166) | * | x |
|-sin(166) cos(166) | | y |

=| x*cos(166) + y*sin(166) |
| -x*sin(166) + y*cos(166) |

new coordinates: ( x*cos(166) + y*sin(166) ,-x*sin(166) + y*cos(166) )
