# SECH

Formulas / SECH
Calculate the hyperbolic secant of an angle.
`SECH(number)`
• number - The value for which you want to calculate the hyperbolic secant (sech). This argument can be a number, a reference to a cell containing a number, or a formula that evaluates to a number.

## Examples

• `=SECH(15)`

In this example, we calculate the hyperbolic secant (sech) of the value with an angle of 15 degrees. The formula results in 6.1180E-07.

• `=SECH(90)`

In this example, we calculate the hyperbolic secant (sech) of the value with an angle of 90 degrees. The formula results in1.6388E-39.

## Summary

The SECH function is used to calculate the hyperbolic secant of an angle. If the number is outside of its constraints, it returns an error.

• The SECH function is used to calculate the hyperbolic secant of an angle.

What is the SECH function?
The SECH function returns the hyperbolic secant of an angle.
What is the argument required by the SECH function?
The SECH function takes a number argument which is the angle in degrees.
