If you are looking for more advanced mathematical calculations, you can use trigonometry functions. For more simple calculations, see Performing simple mathematical calculations.

The following table shows the available trigonometry functions:

Functions | Definition |
---|---|

COS(Number) | Computes the cosine of the entered number, in radians. |

ACOS(Number) | Computes the arc cosine of the entered number, in radians. |

SIN(Number) | Computes the sine of the entered number, in radians. |

ASIN(Number) | Computes the arc sine of the entered number, in radians. |

TAN(Number) | Returns the tangent of the entered number. |

ATAN(Number) | Returns the angle, in radians, where the tangent is entered in the parameter (between negative PI/2 and positive PI/2 |

ATAN2(Number,Number) | Returns the angle of the point y/x in radians, when measured counterclockwise from a circle's x axis (where 0,0 represents the center of the circle). The return value is between positive PI and negative PI. The first parameter to ATAN2 is always the y coordinate. |

DEGREES(Number) | Converts the given number from radians to degrees. |

RADIANS(Number) | Converts the given number from degrees to radians. |

HMAC(algorithm, output_format, key, message) | Returns a keyed hash value using the HMAC method. |
