Hello,
I want to be able to use the student's answer from one question in the evaluation of the correct answer for the next question.
I have found code online for question chaining between separate questions.
Unfortunately I can't seem to be able to do this for either inline or multi-part questions. Is this possible??
Help would be appreciated.
Thanks,
Ray Cohen
PS See the attachment for the question bank containing our attempted code.

How do I change the font permanently so that every time I open a new worksheet I get, say, Arial instead of Times New Roman?
Thanks!

I have a problem where I am performing some matrix operations and the resulting matrix is of rank n-1, where n is the order of the matrix. I want to solve M*x=x, where M is the resulting matrix. Since teh order of M is n-1, I keep getting zero values for all but two of the variables.
What is the best way to get around this problem? I am a Maple novice. Please let me know how to do it in Maple.
Thanks.

During the evolution of my code I have ended up with numerous versions of similar files, each with minute differences to the next.
Is there a way to compare these worksheets?

Hi,
I have been developing some advanced questions for a computational mechanics subject. Unfortunately these questions are running _much_ slower than the sample questions supplied with Maple T.A.
It has been difficult enough to get these questions to actually work, only to find that they are intolerably slow.
We suspect that it may have something to do with the use of the command
maple("printf(MathML:-ExportPresentation($f))");
throughout the questions.
Can someone please offer some advice on how to fix the questions up?
Thanks,

I have the following matrix problem that I am having trouble with. I have the following equation.
A-1 * C * D * A * v = v
A, C and D are of the same order. A & D are diagonal matrices. D is a diagonal matrix with values that are the row sums of matrix C.
I get answers that are reasonable in some instances and zeros in others. I have uploaded a Maple file with what I am doing with some data.
Would appreciate help.
Thanks.

Simple-simple......How do I get the LaTeX code for an input equation?
If I type in the derivative of x squared, right click and select Conversions>LaTeX I get the LaTeX code for the output, i.e. for 2x, not for the derivative of x squared.
Thanks!

Hello!
I have some trouble with getting an explicit solution to a PDE:
f=f(u,v) in IC^4 (IC=complex numbers)
So i have a system of 8 equations, first order, integrable (i.e. solution exists by theory).
I'm getting the following, when calling pdsolve(PDE, fcns), where PDE is the set of the PDEs and fcns are the 4 complex functions f[i], i=1,2,3,4:
"Error, (in pdsolve/sys) duplicated elements (ranking)"
What could it be?
Thx,
yadaddy.

I am using the new Physics package for Maple 11 to do indicial calculations for a continuum mechanics problem.
I need two sets of coordinates for Lagrangian and Eulerian frames. In Maple, I have defined two sets coordinate (X and Y) each with dimension equal to three. Summation is not performed over the time variable, which is treated differently.
If,
X is a point in Eulerian frame, it is related to the Lagrangian frame (Y) by:
X=X(Y,t)
How could I calculate "X[k],K" ? Where the smaller index is in Eulerian coordinates (X), the capital index is in Lagrangian coordinates (Y) and "comma K" (,K) denotes the derivative of X[k] with respect to Y[K]. Could someone show me its implementation using the d_ command.

Hi,
I was wondering if anyone knew how to make MAPLE (10 that is) to diplay all the permutations of a certain number, say 1100 with each digit in a position in a vector. I can only work out how to make MAPLE work out the permutaions- and nopw how to put it into a vector. Also, the permutaions recognise the two ones and zeros as different numbers, when I don't want that. So for the example 1100, I would want MAPLE to output
(1,1,0,0)
(1,0,1,0)
(1,0,0,1)
(0,1,1,0)
(0,1,0,1)
(0,0,1,1)
Can anybody help me with this?
Thanks,
Steph

Hello,
Could anybody please tell me how to plot regions using a procedure in maple. Specifically I have a procedure f of two variables that can output an integer between 1 and n. I want a 2 dimensional plot that gives a different color for each value of this procedure. Any help is much appreciated -- thanks.
PS: As an example I tried this:
> g := proc (x, y) if x <> plot3d(1, x = 0 .. 2, y = 0 .. 2, color = g(x, y));
But this results in the following error:
Error, (in g) cannot determine if this expression is true or false x

Does Maple have any functions that would help to work out nth Term series problems where I'm giving a series of fractions and I need to determine what the nth Term is before I can start working the problems?
Thanks,

I hate to keep comparing but its all I know so have to compare to something. In Mathcad I can drop a table on a worksheet and fill it with values. Then use those values in an equation or plot.
I can also take a series and fill a table based on operations of that series. ie: 1..5 and have it fill a visual table that I can review the values in.
In Maple, when I've messed around with the table() function it ends up putting code on my worksheet and I have to double click it to see what is in it. Is there some easier method to work with tables of values that works more like Mathcad?
Thanks,

I can plot things like this very easily in Mathcad but continue to run into problems with Maple. Mostly just habits I need to change but can't quite figure this one out. Hoping one of you guys can help me along.
I have a problem with the following command:
plot( (-1)^n + n^3 / n^3 +4n^2 + 8, n=1..infinity );
I've tried a smaller range on n but all I seem to get is a blank grid.
Thanks,

Subject: export animation ---> beamer / pdf?
is in the newer releases "animated gif" still the only option
for exporting MAPLE animations?
if so, what is the best way of getting this into a beamer
(via latex/pdflatex and acroread) presentation -- prefer-
rably portable to any machine that has acro-read installed
(want to bring the talk on a memory stick, don't bring the
laptop -- yet not worry about installed helpers).
so far my pdflatex accepts in beamer mp4 movies, and I can
convert single frames of gif to pdf, but not animations.
