- Purpose of use
- Just to check whether term sqrt(a^2+b^2-2*a*b*cos(theta)), in formula for "perimeter", may give correct answer (altrough I have already known that it can''t); for example a=b=2^32, theta =1/2^48, just 26 significant figgures, out of 50, due to cosine being too close to 1, better method: c=sqrt((a-b)^2+4*a*b*(sin(theta/2))^2), but nobody uses it, except Professor William Kahan, a few other people and me :-)

- Maybe you may use term that I have proposed, instead of "ordinary used" one...
