How old was she?

Much younger than I am but still vivacious.

How come she was rude?

To show how bizarre they are, I had been frequenting her line and she started to talk to me.

We talked a little and I could not determine what she was thinking. A couple of weeks ago she acted rather strange and was cold to me so I thought why put up with that and went from then on to other lines. One of those lines has an equally cute girl but somewhat different.

Yesterday when I went on her line she would not look at me. She said hello to the air not to me. I bent my head down to force her to see me and she put her ugly face on.

What was she doing that was strange? Did she have a reason to be cold to you?

By the way, I don't really know how to use a CAS. The only sort of programming stuff I've ever done was about 10 years ago and that was just stuff to do with web design (HTML, PHP) and I've forgotten that all too. What would you recommend as a starting point?

What CAS can you get your hands on?

Yes, a bizarre female reason, using their logic, I can understand it easily.

I don't know, I don't know what's out there...

What reason?

For some of your needs Wolfram alpha is adequate.

There is Sage and there is Maxima, depending on what OS you use.

I was too slow!

You mean she found someone else?

I use Windows XP. I don't know, isn't there something better than that I can learn that might be useful? Sometimes the answers W|A gives are garbage... although it is very useful. Plus I do not have the full version of it.

No, I do not think she has someone else, at least I have not seen him. Women as I explained do not have much patience. After a few times they expect you to ask them out. When you do not it confuses them first, then they get angry.

anonimnystefy uses Maxima and so do I at times. gAr uses Sage effectively on his Linux.

These are really the only choices. Alpha, like all CAS hands out weird answers that have to be fed back into them to get more.

They are so confusing. Seems that the only way to find out what to do is through experience, just being in the situation. It appears that your timing has to be perfect...

I have just downloaded Maxima.

They are unimportant. Her antics are funny.

The standalone or the one that comes bundled with geogebra?

Standalone one I think, it says wxMaxima 12.04.0.

How do I get it to run a code?

It should say 5.28.02 from here

Okay, I will download that one tomorrow.

I was looking at adriana's YouTube channel. She has been watching videos about stopping eating junk food recently.

Heck, there is nothing wrong with that unless you own a junk food company.

She did say she had 2 eating disorders in the past. She has strange habits, when her stomach rumbled she slapped it, until I told her to stop and rubbed her tummy instead before offering her cookies.

So she is a stomach slapper. I have heard of them but only in the Amazon...

No wait, I have never heard of that. Why does she beat her abdomen? Is she mad at it?

I suppose she thinks that the rumbling will go away if she slapped it...

Kind of violent don't you think?

I think I can do your integral using contour integration now.

**In mathematics, you don't understand things. You just get used to them.**

**zetafunc.****Guest**

Not really violent, more odd...

Which integral? sinz/z?

**bobbym****Administrator**- From: Bumpkinland

Yes, that one because I now know why what we did does not work and when it does.

**In mathematics, you don't understand things. You just get used to them.**

Offline

**zetafunc.****Guest**

Because sinz/z is not a rational function?

I thought it might partially be because z = 0 is a removable singularity so you can 'go around' it (keyhole). Although I'm not sure why sometimes they choose to go around the pole (draw a circle around it) or enclose it.

What was the interval again?

Here is an interesting article to download

Are you having issues opening PDFs? It's just blank pages in Firefox.. I will update my Acrobat

The limits were from 0 to infinity. Could extend it to negative infinity too since it's an even function...

Nothing from adriana, not even a text to see how I'm doing. Not just lazy but uncaring too.
