I have a test server up for MapleTA 8.  Where is the option to show a student's name on the questions?

Hi 

I have a big maple sheet on 1000+ lines writing in 2D math in maple 16 that does som calculations on data sets. The sheet can do calculations on 1 data set at the time so I would like to reuse this sheet i a loop. So far I have not found a solution to get a do loop to work over several lines/inputs in a way similar to:

> for i from 1 to 10 do
>   exp1 
>   exp2 

....
>   exp1000+
> od:

Does anyone know how this can be done? 

Program:

restart;

printlevel:=3:

for a from 3 to 30 do

   for b from 23 to 30 do

       for k from b to 30 do

         for d from 4 to 30 do

            for e from 10 to 30 do

  big:=max(sqrt(a^2+b^2), sqrt(k^2+d^2), b+k,e,d+e-a):

  small:=min(sqrt(a^2+b^2), sqrt(k^2+d^2), b+k,e,d+e-a):

I have a somewhat time-consuming numerical integration which is needed for many different parameters so I'd like to parallelize the various integrations. Threads:-Seq should be just the ticket for this; so I write:

respr128:=[Threads:-Seq(evalf(Int(S(ener,Ecrit)*rangeexp(amp,depth/4,t0[128]),ener=0.001..10*Ecrit,method=_d01ajc,epsilon=1.0e-5)),depth=1..36)];

The functions S and rangeexp are defined thus:

S:=(omega,omega_c)->(9*sqrt(3)/(8*Pi)*omega/omega_c...

In MapleTA, how can I carry a value that is calculated/entered in one question over to another question?

As far as I know all variables in MapleTA (such as $v) are local variables (defined within the question) and not global variables (shared by multiple questions).

Hi maplers

I was wondering if it is possible to change default document template and startup code?

How to construct the decomposition-field of the polynomial x^4 + x + 2 over GF(11,1), where GF(11,1)

hi

I have two sets of data namely x[i] and y[i], at first i want to pass a spline from all points (points are in 2d x-y diagram) and then extract some point from that. how can i write the suitable code  in maple? 

thanks

Hi There,

Wondering if anyone was able to assist...

I'm trying to differentiate the following equation with respect to Qin:

f(T,Qin,Qp1,Qp2)=T(Qin-Qp1)*(Qp2-Qin)/(Qp2-Qp1)

I have tried using the diff command but with no luck, Maple is returning D(T)(Qin-Qp1)*(Qp2-Qin)/(Qp2-Qp1)-T(Qin-Qp1)/(Qp2-Qp1) which is not complete. 

Any assistance would be much appreciated.

I want to make an application like the picture in Maple 16. Cuold you help me how to make it ?

Do you have any applications about physics nn maple 16?
