# SECH

The SECH function returns the hyperbolic secant of an angle in radians. It is useful in mathematical calculations involving hyperbolic functions.

## Syntax ðŸ”—

=SECH(`number`

)

`number` | The angle in radians for which you want to calculate the hyperbolic secant. |

## About SECH ðŸ”—

When you are delving into the world of hyperbolic functions and need to compute the hyperbolic secant, the SECH function in Excel comes to the rescue. This mathematical function proves handy in various scenarios when dealing with hyperbolic calculations, particularly in fields like mathematics, physics, and engineering where hyperbolic functions play a significant role.

## Examples ðŸ”—

If you want to find the hyperbolic secant of an angle that measures 1 radian, you can use the SECH function as follows: =SECH(1)

For an angle of 0.5 radians, to calculate the hyperbolic secant using the SECH function, you can enter the formula: =SECH(0.5)

## Notes ðŸ”—

Ensure that the angle provided to the SECH function is in radians to obtain accurate results. If the angle is in degrees, you would need to convert it to radians before using the SECH function.

## Questions ðŸ”—

**What is the range of values that can be passed to the SECH function?**

The SECH function accepts any real number as input for the angle in radians. It is not restricted to a specific range of values.

**Can the SECH function be used for calculating other hyperbolic functions?**

No, the SECH function is specifically designed to compute the hyperbolic secant of an angle. For other hyperbolic functions like hyperbolic sine (SINH) or hyperbolic cosine (COSH), you would use their respective Excel functions.

**In what scenarios would I typically use the SECH function?**

The SECH function is commonly used in mathematical calculations involving hyperbolic functions, such as in differential equations, physics problems, or engineering applications where hyperbolic secant values are required.

**Is there an equivalent function to SECH for computing the hyperbolic cosecant?**

Excel does not have a built-in function for calculating the hyperbolic cosecant directly like SECH for hyperbolic secant. However, you can calculate the hyperbolic cosecant of an angle using the formula `1/SINH(number)` where number is the given angle in radians.
