# SIN

Formulas / SIN
Calculate the sine of an angle using radians.
`=SIN(angle)`
• angle - required argument specifying the angle in radians

## Examples

• `=SIN(PI()/6)`

The SIN function is used to calculate the sine of an angle. This can be useful when working with angles and trigonometry in Sourcetable. For example, this returns 0.5, which is the sine of 30 degrees.

• `=SIN(30*PI()/180)`

The SIN function can also be used to convert degrees into radians. For example, this returns the sine of 30 degrees, which is 0.5.

• `=SIN(PI()/3)`

The SIN function can also be used to calculate the sine of an angle in radians. For example, this will return the sine of 60 degrees, which is 0.8660254037844.

• `=SIN(45*PI()/180)`

The SIN function can also be used to calculate the sine of an angle in degrees. For example, this will return the sine of 45 degrees, which is 0.7071067811865.

## Summary

The SIN function is used to calculate the sine of an angle. It requires the angle to be specified in radians and returns a sine value.

• The SIN function requires a radian angle argument, which must be a number.
