### Circle equation

Hey there, this is my first post here, so hello to everyone.

I have (so far) one question. I have a circle equation like

x2+y2-6y+6=0

I know, that on a paper, I can convert it to the "normal" circle equation, from which I can read the middle point and radius of the circle. And now my question is, how to convert in in maple? I am using the 11th version.

I have tried solving this equation and (x-a)

first, thank you for reminding me, acer.

2nd, I received a mail that someone posted a new comment, but now I can't find my post, where is it?

3rd, can someone tell me how to ask an old question if no one answers for that question?

my old question is here:

### why does evalc give csgn?

Hi,

I am trying to simplify the expression s as given below. (I am not sure why it comes up with all the vector caclulus notation in it but it should display okay when you enter it)

Because of the presence of the exponential imaginary fucntions I thought evalc might be useful but when I use it I get a huge expression with csgn appearing in it. To my knowledge csgn appears when assumptions are not correctly specified - is this so? I can't see any assumption...

### Still there - continued and more

This is a continuation branch of the thread "cut/paste" won't work..." See point #1 below.

1. Why won't #\$%^ Mapleprimes editor let me reply to the original post? I press "add comment" and I get pointed back to the branch two steps back. Anything I write comes out blank when I submit, so now there are two blank replies credited to me! Does that give me points I don't deserve?

2. Classic worksheet isn't "still there". It says so in the readme that classic worksheet...

### My first published paper

Since sometime in 2006 I've been posting my thoughts of and discoveries concerning the MRB constant here on Maple Primes, and I will continue to do so. My hope, however, has been to publish some of my better ideas in a larger forum. I want to thank all of you for putting up with the roughness of many of my ideas when I first posted them. I still hope to refine and publish many of those rough concepts.

Here my first published paper.

When I see a listing of my own posts/questions, I would rather like to see a listing much like in the format shown here www.mapleprimes.com/recent/all  showing the postings less all the summaries.

This would speed up my searching if I, or anyone else, was looking for a particular post of mine, or someone elses.

### how to find my posts easily?

Dear all,

could you please guide me how to find my post quickly on this site? Can I save it somewhere to access it quickly when signing this site again?

Thanks,

Au Nguyen.

### quality of 2D Math on Mapleprimes

This sites needs better rendering of 2D Math.

Here is a sample from the Wikipedia page for Maplesoft, from the pdes example section. The image on Wikipedia is quite nice (it's alt-tags have LaTeX code, which may be a hint).

### vanishing html in posts

This post had a centered H2 header that appeared fine in the wysiwyg post editor during composition but is absent in the Preview or actual Post (in my firefox 3.6.6).

It appeared in the source view, during composition in the editor, like this,

<h2 style="text-align: center;">This my header.</h2>


I tried it also in an earlier submission, with the same result. When I attempt to re-edit that comment, the header was then missing in the source view as well as the posted view.

Could it be, that the submission step causes some html content to vanish?

Hello Maple wizards,

After reading the mapleprimes post http://www.mapleprimes.com/posts/36097-Add-Map-And-Seq on the hidden complexities of using thread-safe versions of add (Threads:-Add), I have been struggling to correct a problem similar to the "escaped k" problem described by Joel Riel...

### some missing uploads available via maple...

Some Posts and Questions contain broken links to files uploaded in the "old Mapleprimes". We've heard that some files (eg. image files) may be irretrievably gone.

But here is a curious page. It had an associated .mw worksheet uploaded. And the link to the uploaded .mw is now broken/stale, at the moment that I write this. But the link to view it with the maplenet viewer, in one's browser, still works. Not only that, but the .mw worksheet can be saved from within that viewer (via a URL distinct from the broken link on the Post).

### Rules for not Maplesoft employees

Will posted recently rules for Maplesoft employees on this site. I think, it might be a good idea to have some rules for not Maplesoft employees, too. Hopefully, they can be created collaboratively. At this time, I came to the following 5.

2. Be polite.
3. Vote up the answers to your questions if you learned something from them, even if they didn't solve the problem.
4. If you answer to somebody else's question - vote that question up - if you answering to it, you found it interesting enough to do that.
5. Don't vote anybody's posts down - that feature is reserved for Maplesoft employees (current or former) to show us what they don't like in our posts.

### sort posts by rank

I'd like to propose a new tab (somewhere) which would allow viewing all posts sorted by thumbs-up. Basically, a way for everyone to see the best posts and replies.

It might have a url something like, http://www.mapleprimes.com/posts/ranked or http://www.mapleprimes.com/recent/ranked

### citation as approval

The thumbs-up may turn out to be an ok mechanism by which this community can recognize good quality posts and responses. But most posts are only likely to get rated thusly by a handful of members willing to do the few extra clicks. I wonder whether there might be other good ways to get approval ratings, either automatically or semi-automatically.

One possibility that occurs to me is citation. The buttons/icons on the Editor menubar already have a Link item (the chain link, for inserting URLs). How about a similar button for adding a citation? The idea being that such a Citation would always be positive, and bring about an additional automatic thumbs-up (maybe allowing more than one-per-member for that particular recipient post). A negative or neutral cite could still be made with the existing Link button.

I'm going to guess that, if all the previous links to Joe Riel's Sorting with Attributes post were such citations, that it would already have more than the number of approvals for the great post class.
