MaplePrimes Questions

I need Maple to evaluate something quite complicated with Groebner:-UnivariatePolynomial


When do I know that maple is at a point where it should be terminated instead of being left to run?

 

Is the output's length proportional to the amount of time used to calculate it?

RC_1D.msim

Dear Community

I'm a newbie in MapleSim trying to run a simple RC circuit simulation. Unfortunately I get the error message "system inconistent, simulation failed", but I have no clue why. I've uploded the model. I'm trying to withdraw a constant current of 0.1A from capacitance C6. I do certainly something wrong. I would be grateful if you could have a look, and help.

Tx. in advance, best regards

One thing I have always found interesting is that exponential growth/decay
is not symmetrical hence:

100*(1+0.01)^2+100*(1-0.01)^2-200 = 0.0200

For example:

If you start with 100 and bet 1% and you win and then again bet 1% of your portfolio value
and you win again your portfolio value will be PW=100*(1+0.01)^2.

If you start with 100 and bet 1% and you lose and then again bet 1% of your portfolio value
and you lose again your portfolio value will be PL=100*(1-0.01)^2. ...

           Which Platonic solids can be obtained as the intersection of the 4d cube   -1<=x1<=1, -1<=x2<=1,-1<=x3<=1, -1<=x4<=1 and a 3d hyperspace A*x1+B*x2+C*x3+D*x4+E=0 (A^2+B^2+C^2+D^2<>0) in R^4? How to find it with Maple?

I'd like to increase the vertical space for the x-axis and horizontal space for the y-axis, between the tick marks on the axes and the labels (e.g. 1, 2, 3, etc.) of the tickmarks.

Is there a way to do this?

Thanks for any help!

 

I would like to set an axis to logarithmic scale, after having loaded the Units[Standard] package.

The command is:

plot3d( function(input), x=-1..1, y=1..1, axis[3]=[mode = log] )

Confoundingly, the error is:

Error, (in plot3d) expecting option mode to be of type identical(linear, log)
 but received Units:-Standard:-log

So the problem is that with(Units[Standard]) hijacks all occurences of log and replaces them with...

Hey there

 

I got a little problem.

I would like to have the positive numbers on the y-axis to point downworth, and of couse the negative going upworth. Is that even possible? 

 

Hope you can help.

 

Thanks

Consider the following two functions, one of which is defined using a differential operator:

DO:=(f,x1,x2)->(sqrt(2)*x1+x2)*D[2](f)(x1,x2)-x2:

a:=(x1,x2,o)->1:
b:=(x1,x2,o)->simplify(DO((x1,x2)->a(x1,x2,o),x1,x2)):

b(x1,x2,o);

The Maple output is (D[2](f))(x1, x2)*sqrt(2)*x1+(D[2](f))(x1, x2)*x2-x2*D[2].

Why does this output contain the variable f, which should be substituted by a?

 

hi all,

To create an observability grammian I have to integrate a matrix with some equations that are difficult to integrate due to multiple time dependent variables. The simplest expression in the matrix is:

z1^2 * sin( z5 * t)^2          (1)

where z1 and z5 are from a state space model with 5 states and are given by:

z1dot = z2     ...

This is somewhat related to the interactive stock quote importer. 

The TSX, DOW jones industrial average, FTSE 100, Heing Seng indexes are all a collection of stocks and their index reflects the movement of those stocks. 

The Dow Jones Industrial average is designated ^DJI in finance.yahoo.com but that symbol is not available in the download.finance.yahoo.com from the interactive stock quoted importer.  Is there perhaps a way I missed...

I am having trouble extracting one part of a return of a solve.

 

> relatie := CD^2 = (AB+BC*cos(beta)+AD*sin(alpha))^2+(BC*sin(beta)-AD*cos(alpha))^2;
> vergelijking := solve(relatie, beta);
 
the solve seems to return 4 expresions and the data type is exprseq. I only need the first expresion (till the first comma) I tried using temp:=vergelijking[1] but that still contains 2 parts separated by a comma.

Has anyone gotten Wigner Rotation to work in Maple. My implementation based on a formula derived in Edmonds, which is equivalent to whatever is on wikipedia, just isn't working. And I don't know where the problem lies. I know for sure that my z axis rotaition works. But I guess my Y-axis rotation is failing for some reason. I'm sure that it matches the formula. I do a Z-Y-Z rotation, so the resulting rotation matrix is real. 

Ideas? Thanks fo any help you can provide!

Why does it give a error? I don't get it and I'm frustrated! Thanks a lot!

Hello guys I'm writing to you becouse I have some problem with miktex and maple.

I exported Maple workshed to tex file, but when I compiled  pdf by Winshell or TexnicCenter I have big problem.

The pdf file looks that:

I dont know why. I did some things ( copy ETC files from Maple to my document folder) but it's dosent help. I red some website and they are writing that:

"The MikTeX installer will create 2 directories that you should know the locations of: texmf and localtexmf. By default, these directories are created as

c:\texmf

and

c:\localtexmf

You are given the option of creating the second one (localtexmf), and I highly recommend that you do, especially if you plan on creating PDF files from Maple. "

But I can't find texfm or localtexfm on my PC

What should I do?? Please help me !  I need this to my graduate project

 

Best regards ( Sorry for my english)

Hi Colleagues
