The Microsoft Excel SINH function returns the hyperbolic sine of a number. The SINH function is a built-in function in Excel that is categorized as a *Math/Trig Function*. It can be used as a worksheet function (WS) in Excel. As a worksheet function, the SINH function can be entered as part of a formula in a cell of a worksheet.

**Syntax**: =SINH( number )

The SINH function syntax has the following arguments:

**Number**: A numeric value used to calculate the hyperbolic sine.

**Example**: Let’s look at some Excel SINH function examples and explore how to use the SINH function as a worksheet function in Microsoft Excel:

**Syntax**: =SINH(A2)

**Result**:

Based on the Excel spreadsheet above, the following SINH examples would return:

**Syntax**: =SINH(A3)**Result**: 1.175201194

**Syntax**: =SINH(A4)**Result**: 0.521095305

**Syntax**: =SINH(A5)**Result**: -1.175201194

**Syntax**: =SINH(A6)**Result**: -3.626860408

**Syntax**: =SINH(A7)**Result**: -10.01787493

**Syntax**: =SINH(A8)**Result**: -122.3439227

**Syntax**: =SINH(A9)**Result**: -4.457105171

**Syntax**: =SINH(A10)**Result**: 2.129279455

**Syntax**: =SINH(A11)**Result**: -0.521095305

**Syntax**: =SINH(A12)**Result**: 6.050204481

**Syntax**: =SINH(A13)**Result**: -2.129279455

**Syntax**: =SINH(A14)**Result**: 122.3439227

**Note**:

- The function returns the #VALUE! Error, if the argument to the function is non numeric.
- The inout number is the angle in radians.
- If you want the result in degrees, multiply the result by 180/PI ().
- If the argument provided is in degrees, first multiply the number in degrees by PI ()/180 to convert it into radians.
- The equation used to calculate the hyperbolic sine is:
