AstroExcel comes with some additional trigonometry functions so you can use degrees in the argument rather than radians, converting degrees to radians is straightforward but with these functions you don’t need to think and reading the formula’s is easy.

DegSIN(degrees) | SIN function but using degrees in the argument |

DegCOS(degrees) | COS function but using degrees in the argument |

DegTAN(degrees) | TAN function but using degrees in the argument |

DegARCSIN(degrees) | ARCSIN function but using degrees in the argument |

DegARCCOS(degrees) | ARCCOS function but using degrees in the argument |

DegARCTAN(degrees) | ARCTAN function but using degrees in the argument |

#### Example

Find the Sine of 90 degrees.

=DegSin(90)
