RE: Pi Approximation Day
Thank you all for your comments!
Yes, I am having an approximately good day (I wish the numbers on the callendar weren't a reminder I am getting older  58 and counting :) Now, time for a little riddle. The following appears to be a pretty bad approximation. It really is, depending on how we look at it. However, when I change only one digit or, equivalently, when I remove one of its parts, it returns a perfect 10digit result on my HP41C, which I am using to evaluate it. BTW, I have used the HP41C for this one because of its 10digit display and a seldom used useful builtin function which most of my Voyagers lack. Too many tips, but it doesn't matter :) Have fun! \(\frac{\frac{26}{7}\frac{6}{11211}}{\left (\frac{4141}{3313}\right ) ^{\frac{3}{4}}}\) Edited to include a pair of parentheses in order to avoid ambiguity
