Returns the cosine of an angle.
Syntax
COS(Value)
Input
Value | is the angle specified in radians |
Domain type: | any Value domain |
Output
COS returns: | a real value |
Domain: | system domain Min1to1 |
Value range: | [-1,1] |
Notes:
Tip:
When the definition symbol = is used, a dependent output map or dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map/column has been calculated.
Usable in
MapCalc, TabCalc, Simple calculators
Examples
Pocket line calculator examples:
? COS(0.79) |
returns 0.704 |
? COS(DEGRAD(60)) | returns 0.500 |
aMapCalc example:
OutMap1 = COS(InMap1)
