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.
