In this case, you can use the formula “=100IMSECH(0.05)+100IMSECH(0.07)+100*IMSECH(0.1)”, which returns a future value of \$133.09.

## Limitations of Excel’s IMSECH Function: Considerations and Workarounds

One limitation of Excel’s IMSECH function is that it can only handle input values that are not equal to zero. To handle input values of zero, you can use a workaround such as defining zero as a very small number.

Example: Suppose you need to calculate the hyperbolic secant of a value that is very close to zero. In this case, you can define zero as a very small number, such as 0.00001, and use the formula “=IMSECH(0.00001)”.

## Versions of Excel That Support the IMSECH Function: An Overview

The IMSECH function is available in Microsoft Excel versions 2003, 2007, 2010, 2013, 2016, and 2019. It is also available in Microsoft Office 365 and Excel for Mac.

Example: If you have Excel 2016 installed, you can use the IMSECH function by typing “=IMSECH(2)” in a cell and pressing enter.

## Accuracy of Excel’s IMSECH Function: How Reliable is It?

The accuracy of Excel’s IMSECH function depends on the input values and the precision of the computer processor. In general, the function is highly accurate for most input values, but there may be some rounding errors for very large or very small input values.

Example: =IMSECH(100) returns 0.0000, which may not be entirely accurate due to rounding errors.
