asin in c

What is asin in c programming?

asin in c is a mathematical function which is used to find arc sine of a given number in radians.

This function is defined in math.h header file.

Prototype

#include<math.h>
double asin(double y);

Parameter

asin function takes floating point value as angle in radians.

Return value

This function returns arc sine of a given number in radians.


Example program for asin in c

#include <stdio.h>
#include <math.h>
#define PI 3.14
int main() 
{
   double x, res, val1;
   x=25.0;
   val1=PI/180;
   res=asin(x*val1);
   printf("The arc sine of %lf is %lf degrees", x, res);
   return 0;
}

While using gcc use below command to add math header.

gcc file_name.c -lm

Code explanation

The variable val1 is defined in terms of degrees and passed to the asin function along with the input value. The result is printed onto the console.
