Math Is Fun Forum

I thought about using that, but found I couldn't explain it in a direct way ... I seemed to be saying that you already had to have DONE something (dv/dx) before you could go ahead. So I went for the "here is what you have, and this is what you do with it" approach.

Point ii is good

Point iii looks like fun!

Hi Bob,

I will have a look at that and get back to you (when I have completed a few other things I am doing now)

Yours, Rod

I use the word "reverse".

What do you all think of the tap/tank example?

And is it good that I gave an example from the Rules of Derivatives before Rules of Integration, or should I just go straight to Rules of Integration?

muxdemux: I simply love programming in Actionscript 3. It is responsive, reliable and each app is self-contained, so library changes don't impact on other live apps.

Glad you all approve, I have made it the live version now.

As in "y=3.105x+2.09" ?
Or perhaps just the slope.

Some old threads are really good ... they have solutions that people search for.

It may not be that much faster either. Say a database has to search an index: it might take 30 steps to find an entry. If you HALVE the size of the index then it might take 29 steps and who would notice? (There are other issues, such as memory and disk, but you see what I mean).

Welcome to the forum Amandaholo. Looking forward to your posts.

Welcome!

Some people own thousands of names, and just sit on them waiting for bidders. I have spent hours and hours thinking of and checking names, pretty much all taken.

And yes, we run a small risk of being "gazumped" ... such is life.
