Something about a bit trigeometry and C++
Okay its suppose to be trigonometry in the title, my mistake.
To all those that know what sin and cos are - I wrote a program that gets a number from a user and shows its sin and cos. Now, I tried it, entering 90 as a number.
sin(90) equals 1, and cos (90) equals 0, but for some reason this output is been displayed:
sin(90) = 0.893997
cos(90) = -0.448074
Here is the code:
Code:
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
cout << "Enter a number";
int num;
cin >> num;
cout << "sin(" << num << ") = " << sin(num) << "\n";
cout << "cos(" << num << ") = " << cos(num);
return 0;
}
Oh, and I know it has nothing to do with the post, but those anybody know how to prevent the program from displaying that "Press any key to continue"?
