Computes the cosine of an input value for an angle measured in radians. The value can be a Decimal or Integer literal or a reference to a column containing numeric values.

In the above, the cosine of angle A is computed as the following:

cos(A) = y/z

The secant of angle A is 1/cos(A), or:

sec(A) = 1/cos(A) = z/y

You can convert from degrees to radians. For more information, see RADIANS Function.


Numeric literal example:

round(cos(radians(30)),3)

Output: Returns the computation of the cosine of a 30-degree angle, which is converted to radians before being passed to the COS function. The output value is rounded to three decimals: 0.866.

Column reference example:

cos(X)

Output: Returns the cosine of the radians values in X column.
