How to calculate the tangent trigonometric value of a given angle using the TAN() function?

TAN(X) is a MySQL built-in function that calculates the tangent trigonometric value of a given angle in radians. For example:

SELECT TAN(0.1), TAN(1.57), TAN(3.14);
  -- +---------------------+--------------------+------------------------+
  -- | TAN(0.1)            | TAN(1.57)          | TAN(3.14)              |
  -- +---------------------+--------------------+------------------------+
  -- | 0.10033467208545055 | 1255.7655915007897 | -0.0015926549364072232 |
  -- +---------------------+--------------------+------------------------+

Reference information of the TAN() function:

TAN(X): val
  Returns the tangent of X, where X is given in radians.

Arguments, return value and availability:
  X: Required. The input angle in radians.
  val: Return value. The tangent of X.
  Available since MySQL 4.0.
