Develop a C program that demonstrate the use of common math functions like sqrt() ,pow() ,ceil() ,round(),sin(), cos(), tan(), abs()

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

//sqrt() ,pow() ,ceil() ,round(),sin(), cos(), tan(), abs()

int main(){
    printf("sqrt %.2f\n", sqrt(64));
    printf("pow %.2f\n", pow(4,2));
    printf("ceil %f\n", ceil(5.32));
    printf("round %f\n", ceil(5.32));
    printf("sin %f\n", sin(90));
    printf("cos %f\n", cos(90));
    printf("tan %f\n", tan(90));
    printf("abs %d\n", abs(-4));

}
Output
