TI-92 - strange results



I tried sin^-1(cos^-1(tan^-1(5))) on my TI-92 (ROM 1.7) and it did indeed
produce some strange results...  Experimenting further, when you do
cos^-1(tan^-1(tt)) (or any other unused name) you get a very unusual
identity involving the entry, 180, and \pi\.  Try it.


cos^-1(x) by itself does the trick as well, but sin^-1(x) and tan^-1(x)
just return themselves. I wonder why?
