I am trying to calculate sin, cos, and tan. The program works but it gives it to me in radians. I needed the conversion to degrees which is sin(x) * PI / 180. when i do this it gives me the wrong answer, can someone help me out. this is my code:

#include <iostream>

using namespace std;

#include <iomanip>

#include <cmath>

const PI = 3.14159265359;

int main()

Code:{ // constant variable can be used to specify array size const int arraySize = 45; int s[ arraySize ]; // array s has 45 elements cout << fixed << setprecision(6); for ( int i = 1; i <= arraySize; i++ ) // set the values s[i] = i++; cout <<"Angle\n" << "(Degrees)" << setw( 9 ) <<"Sine"<< setw(15) <<"Cosine"<< setw(14) <<"Tangent"<<endl; // output contents of array s in tabular format for ( int j = 1; j <= arraySize; j++ ) cout << setw( 2 ) << j << setw( 20 ) << sin(j) << setw(13) << cos(j * PI * 180) << setw(13) << tan(j) << endl; return 0; } // end main
