Neat! I didn't know about the Google graphing facility - I should explore that when my Internet connection is offering a little more speed.

I recall that 'groaner' once really groaned me out! When I was studying engineering, there were no calculators/computers available at all - we entirely depended on slide rules - and it could, with some difficulty (and rather unconvincingly), be done on a slide rule.
