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 23-34 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 23-35 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
