Computes the tangent 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 tangent of angle A is computed as the following:

tan(A) = x/y

The cotangent of angle A is 1/tan(A), or:

cot(A) = 1/tan(A) = y/x

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


Numeric literal example:

round(tan(radians(30)),3)

Output: Returns the computation of the tangent of a 30-degree angle, which is converted to radians before being passed to the tan function. The output value is rounded to three decimals: 0.577.

Column reference example:

tan(X)

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