Cos(number)
Description
Cos calculates the cosine of a number expressing an angle in radians. The required parameter, number, is any numeric expression. The value returned is a double-precision floating-point number that can range from -1 to 1.
To convert degrees to radians, multiply degrees by π/180. To convert radians to degrees, multiply radians by 180/π.
Example
REM Cos Example 'Cos calculates the cosine of a number PRINT "The cosine of 0 is " & Cos(0)
Output
The cosine of 0 is 1
