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.

Thanks.

You simply want to know what angle has that sine. arc sin (c) would be
the function on the calculator you're looking for.

I remember that sin c = excess thrust/weight

What step do I then do to convert sin c into degrees above the horizon?
