Returns the tangent of the given angle.

Syntax

Number     is the angle in radians for which you want the tangent.

Remark

If your argument is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians.

Examples

Formula	Description (Result)
=TAN(0.785)	Tangent of 0.785 radians (0.99920)
=TAN(45*PI()/180)	Tangent of 45 degrees (1)
=TAN(RADIANS(45))	Tangent of 45 degrees (1)
