To calculate sine of 50, enter sin(50), after computation, the result `sqrt(2)/2` is returned.

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

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` sin(`5*pi/6`) `1/2` sin(`0`) `0` 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` sin(`-5*pi/6`) `-1/2`

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 like `sin(x)=1/2` or `2*sin(x)=sqrt(2)` with the calculation steps.
