2. 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...s far as I know, C++ works in radians, not degrees.
