MaplePrimes Questions

Dear Friends:

My original equation is

solve({(1-3*q2)*(1+lamda) = 0, r1*q1-2*r2*XA*(1+lamda) = 0, (1-2*q2)*q2-r2*XA^2 = 0, 1-3*q1+r1*XA = 0}, {XA, q1, q2, lamda})

The answer is

{XA = -1/r1, q1 = 0, q2 = RootOf(r2-r1*_Z+2*_Z^2)/r1, lamda = -1}, {XA = RootOf(-1+9*r2*_Z^2), q1 = 1/3+(1/3)*r1*RootOf(-1+9*r2*_Z^2), q2 = 1/3, lamda = (1/6)*(9*r2*r1*RootOf(-1+9*r2*_Z^2)+r1^2-6*r2)/r2}

 

Two questions:

1. Actually I want...

let x , y in R , say for example

x=0.1243134710481

y=0.1243234710571

Then we can compare the digits where x and y agree and where they differ.

In the example , x and y agree on the first 4 digits , differ on the next digit, agree of the next 5 digits , differ on the next two digits, and agree on the last digit.

Dear all

I've written a program, but it shows an error related to maxfun limit when I run it. Can anyone tell me what the problem is? and how can I solve it? The program and the data file are attached.

Thanks a lot.

Hello all,


This is my first time posting here; I usually find answers to all my questions by searching patiently but I was unsuccessful with this particular issue.


I attend an introduction Maple class and i'm building an animated bike as project. I was already rather comfortable with Maple so i'm trying to show off a little by adding lots of cheesy details to the scene, even if unnecessary. However, some objects such as the sky, which i would like to...

Hi all,

I have this function:

restart:

I2:=g->(200*g)/sqrt(0.04+g^2);

plot(I2(g),g=0..1); 

plot(I2(g),g=1..0);

Those two plots give the same result.

Is it possible to invert the x axes to start from 1 ?

I also tried this below, but the result is as above.

x:=seq([g,I2(g)],g=1..0,-0.02);

pointplot([x],style=line);

Thanks

Hello everybody,

I have this equation J:

> J := Matrix(2, 6, [[j41, j42, j43, j44, j45, j46], [j51, j52, j53, j54, j55, j56]]);

it's a 2 times 6 matrix made with the results of other equation, each one of those small j's are long analytical terms.

Later I want to generate a Matlab code of J using this:

> Matlab(J, resultname = "j4", output = "file.m", optimize);

I use the optimize code at the end because then I avoid getting...

Is there any way to use the final answer obtained on a previous section/subsection and use it on a different section/subsection on the same file?

Thanks, Jose

Hey all,
 I have created a nested while loop to investigate the Riemann zeta function: 

for q to 10 do
 m := 10^(-q);
  for s from 2 to 10 do
   n := 1;
   b := 1;
    while b >= m do
     b := evalf(abs(Zeta(s)-euclid(s, n)));
     n := n+1
    end do;
  print(m, s, n-1)
 end do
end do 

it...

Is there any easy way to browse 3D matrices within maple, other than storing matrices in an array?

How to find the shortest distance between  two points on a cube with Maple? The related twodimensional problem was considered in MaplePrimes, but the thread  seems to be lost. Here are the results of the "shortest distance" search in MP. The results of "shortest distance between two points on a cube" googling do not encourage too.

There was a recent exchange I was a part of on Maple classic versus standard, etc. It disappeared from the list of "recent discussions" so I tried to track it by other means. A keyword search did not immediately return a helpful link, so I thought I would click on my profile and look for my recent comments from the lists there. But I could only find a list of "questions," "answers" and "posts". My contribution there was merely a "comment" and I can't seem to find any list about those...

Hello,

I don't know why I can not login maplesoft and mapleprimes again. Everytime I login the website, www.maplesoft.com and www.mapleprimes.com, an information returned, as the picuture illustrated.

The only way I may login the website is click on the links in my E-mail box. These links are the questions feedback. It seems that if I login the homepage, then...

I just downloaded Maple 15 and am trying to install on a 64-bit Windows 7 machine.

 

About halfway through the installation, there is a step where you are either supposed to supply the path to a batch file that will supply the environment variables that will locate Microsoft Visual C compiler, or supply them later as an option. The instructions say that Maple has a default batch file that will do this, but when that option is chosen, nothing shows up in...

I used to be able to view mapleprimes saved webpages (saved as type archive) offline.

Now I cannot.  All the data is in the file it just won't load the answers and comments part of the page offline?  Does mapleprimes have some script that doesn't run now for offline use?  That's terrible.  This means every page I have saved over the last 4 years is useless unless it loads the answers and comments.  Now they are saved in the file but...
