    Aha! :-)

    "All this calculating  power is a device that was less than $10.00 WOW."

    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.
