a programmer had too much coffee and his boss needs cos(alpha+beta) correctly, especially when alpha or beta or the coffee are close to ninety degrees. A hint: sin() may be appropriate for some input, without committing any sin!!

guessed about overloading, but I am curious, how do you get those bits of code not showing up on your test suite? (also, unrelated, it is a strange world where cos(pi/4+pi/4)=1/sqrt(2)...)

or perhaps there is just some issue with the cody machinery today, some of the 'valid' solutions seem rather 'invalid', and the size computation just plain strange...
