Aha! :-)

Yes, those are terrific. I have two here in my office and one in the living
room. Ya never know when you might need to know the tangent of 37 degrees. Of
course, it looks a little "geeky" to carry around a calculator in public, so
I programmed up a little virtual scientific calculator that I can access
from my cell phone (it's a small web site). That way I can calculate and look
cool doing it. Indeed just last night while having a beer at my neighborhood
pub, a beautiful brunette with a sparkle in her eye walked up and said, "say,
do you happen to know the cosine of 63 degrees?" I replied, "why yes... would
you like 7 or 10 significant digits?" It's moments like those that make me
glad I know my trigonometry.
