A Me-me - mine is mathematical

If you're reading this, consider yourself tagged. So...A meme consists of any unit of cultural information, such as a practice or idea, that gets transmitted verbally or by repeated action from one mind to another. You've no doubt gotten e-mails where you fill in lists of information about yourself. That's one example.

Here are the rules for this one:
1. Pick up the nearest book.
2. Open to page 123.
3. Find the fifth sentence.
4. Post the next three sentences.
5. Tag five people, and acknowledge who tagged you.

I'm not gonna tag five people, but I did get this from Pam's blog. So go for it if you want.

The nearest book is "Calculus: Concepts and Applications". Sorry... but here it is.

"The advantage of the algebraic techniques over the numerical and graphical ones is the ability to get the exact values of a derivative fairly quickly. The disadvantage of the algebraic techniques is that the way you calculate a derivative has nothing to do with what derivative means. You must always bear in mind that a derivative is an instantaneous rate of change."

You just have no idea how true and relevant this statement is. Well, in my world it is.
