C Programming Tutorial
C Programming allows us to perform mathematical operations through the functions defined in
C Math Functions
In the C Programming Language, the asin function returns the arc sine of x.
Syntax
The syntax for the asin function in the C Language is:
double asin(double x);
Parameters or Arguments
A value between -1 and 1. A domain error will occur if x is not between -1 and 1.
Returns
The asin function returns the arc sine of a number represented by x. It will return a value 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 c programming*/ #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 application will output:
The Arc Sine of 0.500000 is 0.523599
