Syntax

TAN(radians: T) → DOUBLE
sql

Type Parameters:

  • T: Any numeric type (TINYINT, SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL)

Arguments

ParameterTypeRequiredDescription
radiansTYesAngle in radians (DOUBLE)

Returns

DOUBLE - Tangent value

Notes

  • Input angle must be in radians (use RADIANS() to convert from degrees)
  • Definition: TAN(x) = SIN(x) / COS(x)
  • TAN(0) = 0, TAN(π/4) = 1, TAN(π) = 0
  • Undefined (infinite) at odd multiples of π/2
  • Period of π: TAN(x) = TAN(x + π)
  • Odd function: TAN(-x) = -TAN(x)
  • Returns NULL if input is NULL
