D toc

Excerpt

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:

Code Block
`tan(A) = x/y`

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

Code Block
`cot(A) = 1/tan(A) = y/x`

snippet Basic

Numeric literal example:

D lang syntax
RawWrangle true ref true derive type:single value: 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:

D lang syntax
RawWrangle true ref true derive type:single value: tan(X) as: 'tanX'

tan(X)

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

D s lang notes

### numeric_value

Name of the column, Integer or Decimal literal, or function returning that data type to apply to the function.

• Missing input values generate missing results.
• Literal numeric values should not be quoted. Quoted values are treated as strings.
• Multiple columns and wildcards are not supported.
