The SIN() function returns the sine of a given angle. It's a basic trigonometric function that calculates the ratio of the length of the side opposite an angle to the length of the hypotenuse, of a right-angled triangle. It's mathematically expressed as SIN(x) = opposite / hypotenuse. In a unit circle, it represents the y-coordinate of a point.

This function can be useful to model repeating seasonal patterns in rolling forecasts.

SIN(Angle)

ArgumentData typeDescription
AngleNumber

The angle in radians for which you want to calculate the sine.

Use the TORADIANS() function to convert degrees to radians.

The SIN() function returns a numeric value between -1 and 1, inclusive.

This function is only available in the Polaris Calculation Engine.

SIN(PI() / 6)

Returns NaN when Angle is NaN.

FormulaResult
SIN(PI() / 2)1.0
SIN(30 * PI() / 180)0.5
SIN(TORADIANS(30))0.5
