## HTML editor still broken...

Bryon wrote:

We published another small update to the editor in MaplePrimes. The problems you were experiencing should now be taken care of.

• If you are referring to the "Sorry, something went wrong" problem, that seems fixed.
• If you are referring to the problem of the HTML editor being a blank window in the old editor, that is not fixed. It is still a blank window.
• If you are referring to the problem of the spacing of bulleted lists, I am not sure about the status of that. This list is spaced correctly, but I could not correct the spacing on an old post.

What exactly does refreshing one's browser entail? I've shut down and restarted Firefox. Should I dump all MaplePrimes cookies? re-install the browser?

## Upper limit of numeric integration...

@antfaulkner The upper limit of numeric integration for your procedures ESys and Fourth is controlled by global variable T, which is set to 4 in the code posted in the original question in this thread (I couldn't find any attached file in your reply). To get the equivalent of soln(5), you'd need to set T to 5 (or more), run ESys or Fourth, and then get the values from (x[N],y[N],z[N]) (or (x[25],y[25],z[25]) assuming that you keep h=0.2).

## Using Maple 17?...

Are you using the latest release of Maple, 17? There are significant advances in Maple 17 that pertain to your question.

## Works so far. Thanks....

@bryon So far, the "Sorry, something went wrong" bug seems to be fixed for me. Thanks.

## Expects a plot like the original distrib...

@acer I think that the Asker was expecting a plot that looks like the original distribution. The reason that their commands didn't provide it is that EmpiricalDistribution is a discrete distribution. Acer, I'm guessing that your solution is equivalent to tallying into bins of width 0.01. Was that your intention? A FrequencyPlot of the sample data also gives such a plot. Why did you send two bins adjacent to zero to NULL? Note the bold streaks along the vertical axis in Markiyan's post of your plots.

## "linear combination" = "dependency relat...

@Manny08 In that worksheet, a "dependency relation" is shown. That means that one column is expressed as a linear combination of the others. That one column is the same as the vector in the present problem which we want to express as a linear combination of the others. That worksheet is literally the complete answer to the present problem.

Here's an attempt explain it in simpler language: The entries in the last column of the RREF are the coefficients that are used with the original vectors to express the original last column as a linear combination of the other columns.

## What is the "reply-to problem"?...

@bryon Could you be more specific as to what you mean by the "reply-to problem"? I am guessing that you don't mean the "Sorry, something went wrong" problem, because I just got that while writing an earlier copy of this reply.

## Hyperlink editor broken in Firefox...

Another MaplePrimes editor bug: The hyperlink editor is broken in Firefox. I tried several times to use it, but all I get is a blank window. It works in Internet Explorer. I mean the hyperlink editor in the old MaplePrimes editor, the one that is used when one clicks Edit on a post.

@Manny08 Why can't you follow the answer in the hyperlink in my first Reply to this post? It is literally the same answer as to the present Question. I could cut-and-paste and put that answer here. Why can't you? I'm not trying to be offensive; I'm really curious what's going on.

## How about showing some example plots?...

How about showing some example plots where you have done this, ones where you think that you did an especially good job?

Also, I do not get an error message when trying to plot your first example.

## Yes, rref...

@Manny08 Yes, the RREF is the key to it all. So how do you input the matrix into Maple and compute the RREF? We've done this before.

## Nearly identical to your earlier questio...

This question is nearly identical to a question that you asked two weeks ago, http://www.mapleprimes.com/questions/145068-How-Do-I-Find-Out-If-A-Matrix-Is-Linearly, and that I answered. Even the vectors are the same. What have you learned from your previous questions and their answers on this list? Can you describe the steps by which you would solve this problem without Maple? I am willing to help you step by step, but I won't just give you the answer.
