+ | ====== Sine (Expression Function) ====== | ||

+ | ===== Purpose ===== | ||

+ | The **Sine** function (SIN) is used to calculate the sine of an angle given in radians, degrees, or gradians. The [[Expression Function - Inverse Sine|inverse sine]] function is also availalble. | ||

+ | |||

+ | {{::sin_initial.png?direct&600|}} | ||

+ | |||

+ | ===== Parameters ===== | ||

+ | The **Sine** function has two parameters, the first of which is required: | ||

+ | |||

+ | ==== Radians ==== | ||

+ | |||

+ | Allowed Inputs: [[Field|field]] value or number | ||

+ | |||

+ | The first required parameter is the angle that the sine will be obtained from either use the use the [[Query Builder]] to choose a field that contains the value or use type a value to enter a number. | ||

+ | |||

+ | ==== Angle Unit ==== | ||

+ | |||

+ | Allowed Inputs: omitted, 'd', 'g' | ||

+ | |||

+ | The second parameter of the **Sine** function is the unit the angle is provided in. If the angle unit is omitted or not recognized then radians will be be used. For an angle provided in degrees use 'd'. For an angle provided in gradians use 'g'. If the angle unit needs to be dynamically stored in a field then the advanced expression builder will need to be used. | ||

+ | |||

+ | |||

+ | ===== Output ===== | ||

+ | |||

+ | The output of the **Sine** function is a number representing the vertical rise of an angle when the radius of the circle is 1. | ||

+ | |||

+ | ===== Example ===== | ||

+ | |||

+ | For example SIN(0.5235987755983), SIN(30,'d'), and SIN(33.3333333333,'g') would result in "0.5". |
