You can make it a little easier on yourself, for small angles just
multiply the sine by 57. For example, a 10 degree climb angle is
pretty steep. sin(10) is 0.1736. The approximation I mentioned would
return 9.9 degrees (that's because for small angles sin(angle) is
pretty much equal to tan(angle) and to the angle itself if measured in
radians.

Cockpit math is hard enough. Cockpit trigonometry? Are you kdding??
