This function returns the tangent of the specified angle.
TAN(angle)
This function can take any real number as an argument. The angle argument is the angle in radians for which you want the tangent.
If the angle is in degrees, multiply it by PI/180 to convert it to radians.
Accepts numeric data. Returns numeric data.
TAN(B3)
TAN(R3C2)
TAN(45*PI()/180) gives the result 1
TAN(RADIANS(20))
