No, the example does not imply that those two functions are the same. It just says that (by applying l'Hospital's rule) they have the same limit as...

1. Hey Peter!

I edited your post to remove the duplicate content. Sorry for the late reply, I was busy "powering through" a tedious 3 hour project.
2. Glad to hear that resolved the issue! I thought perhaps forcing your browser to reload the script by removing it from your cache might do the trick.
4. Hey Peter,

No, there have been no changes in that regard, at least that I know of. Do you visit any other sites that use MathJax? If so does it render there?

Best Regards,

Mark.
5. Good deal, Peter! I wish I had a nickel for every time a problem is corrected by ditching IE and using a modern standards compliant browser.
6. I would try another browser...IE is notorious for being problematic.
7. Hello Peter,

No changes to composing posts have been made. What browser are you using? What OS?
8. Thank you for your kind words Peter, I really appreciate them. I'm always happy to help!
9. Hey Peter,

You attached 4 images, but only 3 of them were attached inline...I deleted the duplicate.

Best Regards,

Mark.
10. Hey Peter,

I am very sorry to hear that you had to undergo eye surgery, but I hope everything went well and that your recovery is complete and as speedy as possible.

Best Regards,

Mark.
