recent edit to Rolle's theorem
Your edit to Partial fraction decomposition definitely made the formula more readable. However, your edit to Rolle's theorem introduced an error. Please consider your edits very carefully before making changes to technical articles. Thank you, Lunch 06:05, 14 February 2007 (UTC)

PS. Blanking warnings from your talk page is considered by some to be poor form.

Re: Rolle's Thm
Hi, I'm one of several users of the IP address 66.136.237.246. I'm not the one that made the edit you discussed on User_talk:66.136.237.246, but I agree with the person who did. Intervals cannot be closed on infinity, as infinity is not actually a number. I didn't want to revert the reversion though without discussing it with you. I'm convinced, however, that the edit made was correct. — Preceding unsigned comment added by 66.136.237.246 (talk)


 * As I mentioned (indirectly) in the edit summary, the theorem still applies to a curve with a vertical tangent. That is, you can (locally) apply the theorem to the inverse of the desired function.  The section could be worded better, and the notation $$[-\infty,+\infty]$$ is non-standard, but it is correct.  If you make a change to clarify the statement, that would be welcome, but please do not reintroduce the error.  Thanks, Lunch 19:29, 14 February 2007 (UTC)
