This program demonstrates the usage of various mathematical functions provided in the "math.h" header file of C. It initializes a variable "a" with the value 0.25 and then uses various functions such as abs(), acos(), asin(), atan(), atan2(), cos(), sin(), tan(), and sqrt() to perform mathematical operations on "a" and store the result in variable "b". Finally, it prints the value of "b" using the printf() function.

Program:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main() {
   	float a;
	float b;
	float pi = 3.14;
	a = 0.25;
	printf("value a = %.2f \n",a);
	b = abs(-a);
	printf("abs(a)=%.2f \n",b);
	b = acos(a);
	printf("acos(a)=%.2f \n",b);
	b = asin(a);
	printf("asin(a)=%.2f \n",b);
	b = atan(a);
	printf("abs(a)=%.2f \n",b);
	b = atan2(a,5);
	printf("atan(a,5)=%.2f \n",b);
	b = cos(a);
	printf("cos(a)=%.2f \n",b);
	b = sin(a);
	printf("sin(a)=%.2f \n",b);
	b = tan(a);
	printf("tan(a)=%.2f \n",b);
	b = sqrt(a);
	printf("sqrt(a)=%.2f \n",b);
	return 0;
}

Output:

value a = 0.25
abs(a)=0.00
acos(a)=1.32
asin(a)=0.25
abs(a)=0.24
atan(a,5)=0.05
cos(a)=0.97
sin(a)=0.25
tan(a)=0.26
sqrt(a)=0.50
