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:

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"?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; }
