Edit Question
Title
Body
I am trying to do a simple trigonometric calculation in C++. The following is an example of the problem I am having with this. As far as I know, C++ works in radians, not degrees. So conversion from radians to degrees should be a simple case of multiplying by 180 and dividing by pi. A simple test is tan(45), which should equate 1. The following program produces a value of 92.8063 however... #include <iostream> using namespace std; #include <math.h> int main(){ double a,b; a = tan(45); b = a * 180 / 3.14159265; cout << b; return 0; } What is wrong?
