ACOS Function in C

by

The ACOS Function in C programming is one of the Math Library Function. It used to calculate Trigonometry Arc Cosine value for the user specified expression, or value.

In this article we will show you, How to use this ACOS function with example.

TIP : Please refer COS Function article to calculate the Cosine value of specified expression.

Syntax of ACOS Function in C

The basic syntax of the acos in C Programming is as shown below.

double acos(double number);

ACOS Function in C Example

The acos Function in math library helps you to find the trigonometry Arc Cosine for the specified values.

This program, ask the user to enter his/her own value, and then it will find the arc cosine value of the user entered one

/* Example for ACOS Function in C Programming */

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

int main()
{
  double acosValue, number;

  printf(" Please Enter the Floating Value between -1 to 1 :  ");
  scanf("%lf", &number);
  
  acosValue = acos(number);
  
  printf("\n The Arc Cosine value of %lf = %f ", number, acosValue);
  
  return 0;
}
