Now, some documents on math, squares, and quadratic functions.

Show Quads10


This notebook will take a quick look at the quadratic / square function.

Equation 10: The Linear

Here it is, the first page of my Math Musings.

Math Musings

The above is not very interesting. However, it is certainly a graph of one of the simplest functions. There, this is a math musing - the first most. (Yes, not a post, more like a math-post / most.) (Confusion is intentional.)

Powering Up

Hi, I'm back.

= The FloatingPoint Designs web site was in transition. Now, the 3 blogs of (XEmacs, Linux, and Blogset) FPD are merged into MediaBin.

= Next, I'm starting a new blog on Math Forms. Stay tuned.

Update: Dec 2006

Here it is, December 2006 already. Where did the year go?

I've had fun doing XEmacs posts & digging deep into this complex editor. This isn't the end of tips on XEmacs. However, the frequency has slowed, and "I believe" all the basics to using XEmacs are done.

Things are going to be changing on my web site, soon. I'll try to occasionally post here.

Tip: Grab A Value

Question: Ok, I've typed this magic number in my document & need to run a calculation on it. How can I bring it into calc? . . .

Answer: Use the grab command of the calc package.

= First type your number, in the document. Then, select it to the end of your number, and grab.

• Find your number, move to the first digit, select start, and go to end: Ctrl-space.
• Grab command: Alt-#, g.
• Perform your calculations. If you have a result to return to the document? Move to the line with the desired result, and kill that line & quit (calc): Alt-k, q. (Otherwise, leave with a q.)
• Last yank it back: Ctrl-y.

= Note: Just hitting the q key. Quits out of calc. It isn't necessary to Alt-#, c; to leave.

Tip: Run A Quick Calc

Question: Ok, do I have to enter this calc mode & mess with it's buffer? . . .

Answer: No, you don't. There is a quick calc command, also. However, you cannot kill (the answer) to paste it.

= It will let you enter the expression in the mini-buffer (or echo area) and not jump you to another buffer view. Thus, the quick moniker, and it vanishes. When you resume typing on the file.

• Enter the quick calc mode: Alt-#, q.
• Enter an algebraic expression, hit enter, and view your answer.
• Exit quick calc mode: Alt-#, q.
