using namespace std;

int main ()

{

int PI = 3.142;

cout<< "cos(60) = " << cos ( 60.0 * PI / 180.0 )<<endl;

cout<< "sin(60) = " << sin ( 60.0 * PI / 180.0 )<<endl;

cout<< "tan(45) = " << tan ( 45.0 * PI / 180.0 )<<endl;

cout<< "acos(0.5) = " << acos (0.5) * 180.0 / PI<<endl;

cout<< "asin(0.5) = " << asin (0.5) * 180.0 / PI<<endl;

cout<< "atan(1.0) = " << atan (1.0) * 180.0 / PI<<endl;

cout<< "2^3 = " << pow(2,3)<<endl;

cout<< "sqrt(49) = " << sqrt(49)<<endl;

cout<< "ceil(3.8) = " << ceil(3.8)<<endl;

cout<< "floor(2.3) = " << floor(2.3)<<endl;

cout<< "trunc(5.3,2) = " << trunc(2.3)<<endl;

cout<< "round(4.6) = " << round(4.6)<<endl;

cout<< "remainder(18.5,4.2) = " << remainder(18.5 ,4.2)<<endl;

cout<< "fmax(100.0,1.0) = " << fmax(100.0,1.0)<<endl;

cout<< "fmin(100.0,1.0) = " << fmin(100.0,1.0)<<endl;

cout<< "fdim(2.0,1.0) = " << fdim(2.0,1.0)<<endl;

cout<< "fabs(3.1416) = " << fabs(3.1416)<<endl;

return 0;
