Program 2

#include <iostream>
#include <cmath>
using namespace std;

int main()

{

       const double PI = 3.141592653;

       int degrees;

       double radians;

       cout << "Enter a value for the degree of an angle\n";

       cin >> degrees;

       // translate the formula for converting degrees to radians into C++:

       //    

       // degrees x PI

       // ------------   = radians

       //     180

       radians = _____________________________________;

       // Refer to p. 127 for help below. Note: Sine, Cosine, and Tangent

       // use radians and not degrees to compute correctly.

       cout << "The degrees entered were: " << _____________;

       cout << "\nThis equals: " << radians << " in radians\n";

       cout << "The sine of the angle entered is: " << _________________;

       cout << "\nThe cosine of the angle entered is: " << ________________;

       cout << "\nThe tangent of the angle entered is: " << _______________;

       cout << endl;

       system("pause");

       return 0;

Submit your program source code to the Blackboard submission module as a Word document. Include a screen shot of your output (Ctrl-Alt-Print Screen) as well. Do this for BOTH programs to receive credit for your assignment.

Sample Output:

Enter a value for the degree of an angle

45

The degrees entered were: 45

This equals: 0.785398 in radians

The sine of the angle entered is: 0.707107

The cosine of the angle entered is: 0.707107

The tangent of the angle entered is: 1
