TAN
The TAN function calculates the tangent of an angle, the ratio of the sine to the cosine.
TAN(radian-angle)
 radian-angle: An angle in radians.
Notes
If you measure angles in degrees instead of radians, you can use the RADIANS function
to convert degrees to radians for the TAN function.
If you measure angles in degrees instead of radians, you can use the RADIANS function
to convert degrees to radians for the TAN function.
If you want to express radians as a multiple of pi, you can use the PI() function to
provide a value for pi.
provide a value for pi.
Examples
If cell A1 contains "text" and cell B1 is empty:
T(A1) returns "text" and T(B1) returns nothing.
Examples
TAN(1) returns 1.557407725, the tangent of 1 radian (approximately 57.3 degrees).
TAN(RADIANS(45)) returns 1, the tangent of a 45-degree angle.
TAN(3*PI()/4) returns -1.
