# SIN

The SIN function calculates the sine of an angle expression. The result returned by SIN is a decimal value with the same dimensions as the specified expression.

Return Value

DECIMAL

Syntax

SIN(angle-expression)

Arguments

angle-expression

  A numeric expression that contains an angle value, which is specified in radians.

Examples

Example 21-34 Calculating the Sine of an Angle in Radians

This example calculates the sine of an angle of 1 radian. The statements

    DECIMALS = 5
    SHOW SIN(1)

produce the following result.

    0.84147

Example 21-35 Calculating the Sine of an Angle in Degrees

This example calculates the sine of an angle of 30 degrees. Since `1` degree = `2*(pi)/360` radians, `30` degrees is about `30*2*3.14159/360` radians. The OLAP DML statement

    SHOW SIN(30 * 2 * 3.14159 / 360)

produces the following result.

    0.50000
