asin function(Arc Sine) in C Language – example and detail

In the C Programming Language, the asin feature returns the arc sine of x.


The syntax for the asin characteristic in the C Language is:

double asin(double x);

Parameters or Arguments

x A fee between -1 and 1. A area error will take place if x is not between -1 and 1.


The asin characteristic returns the arc sine of a quantity represented through x. It will return a cost between -π/2 and π/2.

Required Header

In the C Language, the required header for the asin function is:

#include <math.h>

Applies To

In the C Language, the asin function can be used in the following versions:

ANSI/ISO 9899-1990

asin Example

/* Example using asin by */

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

int main(int argc, const char * argv[])
    /* Define temporary variables */
    double value;
    double result;

    /* Assign the value we will find the asin of */
    value = 0.5;

    /* Calculate the Arc Sine of value */
    result = asin(value);

    /* Display the result of the calculation */
    printf("The Arc Sine of %f is %f\n", value, result);

    return 0;

When compiled and run, this software will output:

The Arc Sine of 0.500000 is 0.523599
