Negative Reference Angle Formulas

Quadrant I -- degree( r ) = | degree |

Quadrant II -- degree( r ) = pi - | degree | -- degree( r ) = 180 - | degree |

Quadrant III -- degree( r ) = | degree | - pi -- degree( r ) = | degree | - 180

Quadrant IV -- degree( r ) = 2(pi) - | degree | -- degree( r ) = 360 - | degree |
