## Special sine values table

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

sin(`2*pi`) | `0` |

sin(`pi`) | `0` |

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

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

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

sin(`pi/6`) | `1/2` |

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

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

## Main properties

`AA x in RR, k in ZZ`, `sin(-x)= -sin(x)` `sin(x+2*k*pi)=sin(x)` `sin(pi-x)=sin(x)` `sin(pi+x)=-sin(x)` `sin(pi/2-x)=cos(x)` `sin(pi/2+x)=cos(x)`

## Derivative of sine

The derivative of the sine is equal to cos(x).

## Antiderivative of sine

The antiderivative of the sine is equal to -cos(x).

## Properties of the sine function

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

## Equation with sine

The calculator has a solver which allows it to solve equation with sine of the form **cos(x)=a**. The calculations to obtain the result are detailed, so it will be possible to solve equations choose `sin(x)=1/2` or `2*sin(x)=sqrt(2)` with the calculation steps.

Syntax :sin(x), where x is the measure of an angle in degrees, radians, or gradians.

Examples :sin(`0`), returns 0

Derivative sine :To differentiate function sine online, it is possible to use the derivative calculator which allows the calculation of the derivative of the sine function

The **derivative of sin(x)** is derivative_calculator(`sin(x)`)=`cos(x)`

Antiderivative calculator allows to calculate an antiderivative of sine function.

An **antiderivative of sin(x)** is antiderivative_calculator(`sin(x)`)=`-cos(x)`

The limit calculator allows the calculation of limits of the sine function.
