However, the process requires the integration of an already positive function. That is, [1 + (f '(x))^2]^0.5 is necessarily positive because the derivative is squared. That said, the answer to your question is, no. Regards, Rich B.[/color] rmath4u2@aol.com

Another more geometric approach would be to consider that if this was true we would be talking about [color=#FF0000]negative length[/color]. Now does that make sense?
