Write a C Program by using sqrt() , sin() , cos() and tan() Functions

Mathematical Functions:

1. C provides a large number of Library Functions which perform specific operations. 
2. Mathematical functions are also included among these Library Functions. 
3. C Mathematical Functions are defined in the Header File math.h.

Statement of C Program: This Program illustrates the use of sqrt() , sin() , cos() and tan() Functions:

#include<stdio.h>

#include<conio.h>

#include<math.h>

main()

{

float a , b , sq , sinx , cosx , tanx;

clrscr();

x = 4;                                                         /* Initialise */

y=30;

sq = sqrt(x);

y = 30*(3.142/180);                              /* Convert to Radian */

sinx=sin(y);

cosx=cos(y);

tanx=tan(y);

printf("Square root of x = %f\n" , sq);

printf("Sine value of y = %f\n" , sinx);

printf("Cosine value of y = %f\n" , cosx);

printf("Tangent value of y = %f\n" , tanx);

getch();

}

 Output:

 Square root of x = 2

 Sine value of y = 0.500059

 Cosine value of y = 0.865991

 Tangent value of y = 0.577441
