This example illustrates how to apply basic trigonometric functions to your transformations. All of the functions take inputs in radians.

**Sine.**See SIN Function.**Cosine.**See COS Function.**Tangent.**See TAN Function.**Cotangent.**Computed as 1/TAN.**Secant.**Computed as 1/COS.**Cosecant.**Computed as 1/SIN.

In the following sample, input values are in degrees:

X |
---|

-30 |

0 |

30 |

45 |

60 |

90 |

120 |

135 |

180 |

** Transformation:**

In this example, all values are rounded to three decimals for clarity.

First, the above values in degrees must be converted to radians.

Sine:

Cosine:

Tangent:
