COS

The COS function calculates the cosine of an angle expression.

Return Value

NUMBER

The result returned by COS is a value with the same dimensions as the specified expression.

Syntax

COS(angle-expression)

Parameters

angle-expression

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

Examples

Example 7-52 Calculating the Cosine of an Angle in Radians

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

DECIMALS = 5
SHOW COS(1)

produce the following result.

0.54030

Example 7-53 Calculating the Cosine of an Angle in Degrees

This example calculates the cosine of an angle of 60 degrees. Since 1 degree = 2 * (pi) / 360 radians, 60 degrees is about 60 * 2 * 3.14159 / 360 radians. The statement

SHOW COS(60 * 2 * 3.14159 / 360)

produces the following result.

0.50000
