# sinh() Function Example in C Programming

In this source code example, we will see how to use the sinh() function in C programming with an example.

## sinh() Function Overview

The sinh() function in C calculates the hyperbolic sine of a given number. This mathematical function is analogous to the regular sine function but works over a hyperbolic angle instead of a circular angle. It's particularly useful in many areas of engineering and physics, like when working with hyperbolic trajectories. The function resides within the math.h library.

Key Points:

- To use the sinh() function, you need to include the math.h header.

- The argument provided can be any real number.

- When compiling your program, ensure you link the math library using the -lm flag.

## Source Code Example

``````#include <stdio.h>
#include <math.h>  // Necessary for sinh()

int main() {
double value, result;

// Prompt user for the value
printf("Enter a value to compute its hyperbolic sine: ");
scanf("%lf", &value);

// Calculate the hyperbolic sine of the value
result = sinh(value);

// Display the result
printf("Hyperbolic sine of %.2lf is: %.2lf\n", value, result);

return 0;
}
``````

## Output

```Enter a value to compute its hyperbolic sine: 1
Hyperbolic sine of 1.00 is: 1.18
```

## Explanation

1. We start by including the required header files: stdio.h for standard I/O functions and math.h to access the sinh() function.

2. In the main() function, we solicit a value from the user.

3. The sinh() function is then employed to calculate the hyperbolic sine of the provided value.

4. The computed result is then showcased on the console.
