The trigonometric function sec allows to calculate the secant of an angle expressed in radians, degrees, or grades.

cosec online

The cosecant trigonometric function noted cosec, allows the calculation of the cosecant of an angle, it is possible to use different angular units: the radian which is the default angular unit, the degree or the grade. The cosecant function is equal to the inverse of the sine function, `cosec(x)=1/sin(x)`

Note that the cosecant function is able to recognize some special angles and make the calculations with special associated values in exact form.

To **calculate the cosecant of an angle** in degrees, you must first select the desired unit
by clicking on the options button calculation module. After that, you can start your calculus.

To calculate cosecant of 45, enter cosec(45), after calculation, the restults is returned.

To calculate the cosecant of an angle in gradians, you must first select the desired unit by clicking on the options button calculation module. After that, you can start your calculus.

To calculate cosecant of 50, enter cosec(50), after computation, the result is returned.

Note that the cosecant function is able to recognize some special angles and do the calculus with special associated exact values.

The cosecant admits some special values which the calculator is able to determine in exact forms. Here is a table of
the **commoncosecant values**:

Value | cosec | Result |
---|---|---|

`pi/6` | cosec(`pi/6`) | `2` |

`pi/4` | cosec(`pi/4`) | `2/sqrt(2)` |

`pi/3` | cosec(`pi/3`) | `2/sqrt(3)` |

`pi/2` | cosec(`pi/2`) | `1` |

`2*pi/3` | cosec(`2*pi/3`) | `2/sqrt(3)` |

`3*pi/4` | cosec(`3*pi/4`) | `2/sqrt(2)` |

`5*pi/6` | cosec(`5*pi/6`) | `2` |

The derivative of the cosecant is equal to `-cos(x)/sin(x)^2``=``-"cotan"(x)*"cosec"(x)`.

The antiderivative of the cosecant is equal to `1/2*ln((1-cos(x))/(1+cos(x)))`.

The **cosecant** function is an odd function, for every real x, `cosec(-x)=-cosec(x)`.
The consequence for the curve representative of the cosecant function is that it admits the origin of the reference point as point of symmetry.
