I am trying to plot a 3D function and as soon as I hit enter this error pops uo saying, "Error, (in plot3d) expected ranges but received equations x=-2..2 and y=2..-2"

 

Any help would be greatly appreciated.

 

Hi

I have a problem with Maple. I would like to see an answer in numbers this equation, but instead I get more equations. I've tried to use evalf but that didn't work for me.

Is there someone who can look at this and help me?

Thanks in advance!

 

This is my Maple output (sorry for the uglyness):

> SomAx := Ax+F2+F6*sin(beta)-F1*sin(gamma) = 0;
print(`output redirected...`); # input placeholder
    ...

I would like to know how to find an extreme (max) point of function of two variables:

and how to manage with this error

"Warning, solutions may have been lost

                                                  ...

I migrate to Mac OS X 10.6.6.

And Maple 13 and 12 (with or without Firewall)

do not work any more : "kernel connection is lost".

(When Firewall is working, it has all the necessary permissions.)

The mserver (64 bits) mobilize 100 % of CPU two or three times

(and I have to wait at least 1 minute each time), then disconnection appears.

I reinstalled Maple 13 and get the same results.

What can I do ?

Can I  upload a worksheet in MapleCloud with some security code that allow the person just read the worksheet and not download/save in their own computer? Is there a option in MapleCloud like this or any worksheet in MapleCloud can be viewed and save?

 

Thanks Washington Inácio

Can someone kindly write me some code to unscramble a jumbled word into english.

eg: input: "atc"; output: "cat",'act".

it will need to invoke the inbuilt dictionary.

thx

If I use a binary {0,1} linear program the cardinal constraint ie control the
number of 1's (long positions in portfolio) works beautiful. See attached worksheet.

The problem starts when I convert the problem into a constrained integer {-1,0,1}
linear problem where -1= short position, 0=no position and 1=long position.

In the first example when we add the constraint  add(w[i], i = 1 .. NC) = 4

Dear friends,

 

I have to generate several pages of tables with numbers (using the option Matrix in Maple) and to write them in Latex.

Is there some option to be able to include  titles of the tables, names of the columns, notes on the bottom of the pages?

 

I saw some question like this in mapleprimes, but it was time ago that I wonder that now maybe the Latex Output of Maple has improved.

 

Thanks for your attention,

Hey folks I'm trying to solve equations using isolve for which I want conditions on my two variables x and y. I would like them to be both positive and x>y. The problem I'm having with isolve now is that I can't manipulate the output I get. Perhaps there is a way to do this but I can't see how yet. It would produce something like {x = 1, y = 2} for example and I can't extract the numerical values from it (at least using [] operators). I currently don't have access to maple...

Hi everybody,

I have a little problem with Maple 14.01:

I would like to export a figure created with plot3d as an eps file. I do so by simply right-clicking on the figure and than on export -> encapsulated postscript. The problem: it does not work properly:

With Maple 12, I get a 2mb large vector graphic. If I export the same figure under Maple 14.01, the file is only 148kb large und not a vector graphic - when I open it with Inkscape, it just looks like an ordinary jpg-picture.

1.For win 8, does there exist an arm version maple in future?

2.Will it possible to use gpu acceleration for symbolic computation in maple?

I have 8 equations (eq1, eq2, eq3, eq4, eq5, eq6, eq7 and eq8) with 8 varibles A1[n], A2[n], C1[n], C2[n], B2[n], A[k,i], D2[n], A[0,i] and where n=1..nn, k=1..nk, i=1..Q

I have some difficulties to get the matrix form AX=b

Thanks in advance for any help

I attached my maple code

Would much value shared experience or solutions on this

Thanks

Hi. I wanted to figure out how to plot a boundary value problem in Maple. It is a nonlinear, fourth order ordinary differential equation with four boundary conditions. The BVP has the form (d⁴/dt⁴)-3(d²/dt²)(d/dt)=0, with boundary conditions x(0)=0, x(1)=60, (d/dt)(x)(0)=0, and (d/dt)(x)(1)=0. Thanks.
