What is SECH function in Excel?
SECH function is one of the Math and Trig functions in Microsoft Excel that returns the hyperbolic secant of an angle.
Syntax of SECH function
The SECH function syntax has the following arguments.
Number: Number is the angle in radians for which you want the hyperbolic secant.
SECH formula explanation
- The absolute value of number must be less than 2^27.
- If the angle is in degrees, either multiply the angle by PI()/180 or use the RADIANS function to covert the angle to radians.
- If number is outside of its constraints, SECH returns the #NUM! error value.
- If number is a non-numeric value, SECH returns the #VALUE! error values.
Example of SECH function
Steps to follow:
1. Open a new Excel worksheet.
2. Copy data in the following table below and paste it in cell A1
