The angle in radians for which you want the tangent.
The TAN function calculates the tangent of an angle provided in radians. If your angle is in degrees, you must multiply it by PI()/180 or use the RADIANS function to convert it.
=TAN(RADIANS(45))→1Calculates the tangent of 45 degrees by converting it to radians first.
