Anyway, you state we can say that summation is infinity. I'm ok with that. How in the heck can we say with a straight face it equals -1/12?? That answer gives us a negative number as a sum of positive number and also a fractional number less than the first number to be summed. It must be absolutely false! So why is it true?Anonymousnoreply@blogger.com
