Question

Explain sinh()  Math Function in C

Answer 1

The sinh() function in C is a mathematical function that calculates the hyperbolic sine of a given angle. It is defined in the math.h library and can be used to perform calculations involving hyperbolic functions.

The hyperbolic sine function is defined as:

sinh(x) = (e^x - e^(-x)) / 2

Here's an example code that demonstrates the usage of the sinh() function:

#include <stdio.h>
#include <math.h>

int main() {
    double angle = 1.5; // Example angle in radians
    double result = sinh(angle);

    printf("The hyperbolic sine of %f is %f\n", angle, result);

    return 0;
}
 

In this example, we include the necessary stdio.h and math.h header files. We then define an angle of 1.5 radians as an example. We pass this angle to the sinh() function to calculate its hyperbolic sine. The result is stored in the variable result.

Finally, we use printf() to display the angle and its corresponding hyperbolic sine value on the console.

When you run this code, the output will be:

The hyperbolic sine of 1.500000 is 2.129279
 

This indicates that the hyperbolic sine of 1.5 radians is approximately 2.129279.
