Hi there,

I am wondering if it is possible to create custom feedback based on results of tests or exercises?  For example, if a user receives 50-60% I would want them referred to a specifc URL or set of static web pages providing more detailed informtion on the given topic, however, if they receive , say, 61 - 70% they could be referred to yet a different URL, web site, etc. 

 

thanks,

Jeff

hi all...i want to write a procedure just to execute a set of maple commands without any input args e.g do some calc and plot series of graphs..i am facing 2 problems

1.inside procedure all lines are not  displayd only last line of command inside the proc is diplayed after execution

2.im choosing a proc to exec a series of commands because i can use the debugger to debug the set of codes else i cannot.

I would like to change the way arrows looking Maple under fieldplot3d. Particularly I would like them to have a rounded head and a simple stick for the base of the arrow. Anyone know how to do this? I have seen it done before, just not sure how to implement the code to do it. Thanks in advance!

I was curious if anyone has every seen an english translation of Jordan's Cours d' Analyse. I've read many author comments praising his work and was interested in trying to find a copy in english. Anyone care to comment?

I'm using maple to optimize a certain problem. I have two matrices, A and B both of size m by n. Now I want to maximize alpha(a scalar) such that Bx>=alpha*Ax for arbitrary x. So I gave maple the following problem: input:=evalm(A&*X): > output:=evalm(B&*X): > for i from 1 to m do > constraint[i]:=output[i]-alpha*input[i]>=0; > od: > Constraints:=seq(constraint[i],i=1..m); > sumconstraint:=add(x[i],i=1..n)>=10; oplos:=NLPSolve(alpha,{Constraints,somconstraint},maximize=true,assume=nonnegative); My problem is that maple sometimes can't come up with an answer and tells me:

Given "(x + y/z)" as input, how do I get the same expression in the form of "(xz+ y)/z". I need to make this conversion, so that I can discard  the denominator and use the numerator "xz +y" as a monomial in Groebner Basis.

I currently run Maple 10. I am a math teacher in a public school. Do you think I will benefit from upgrading to Maple 12? Any cool features?

Does Maplesoft has an online version of Maple's user manuals? I know there are pdf versions. Thanks!

Hi:

I will really appreciate it if I can get some help with evaluating 2500(1+ r/4)^(4*5) with r taking multiples values such as 6, 10 etc.

So far I am aware of the basic eval command... eval(2500(1+r/4)^(4*5),r=6). What I want to do is evaluate this expression for multiple values of r. Thanks in advance!!

I want to have a solved example of linear programming model in maple software or any other software that has linear programming model

I'm trying to graph nonlinear systems of inequalities.  INEQUAL works only with linear systems.  Someone in this forum suggested IMPLICITPLOT with the option FILLED = TRUE, but this doesn't always give the desired results since that option only gives the area between the curve and the x-axis a solid color.  What I need is the power of OPTIONSFEASIBLE, OPTIONSEXCLUDED, OPTIONSOPEN, and OPTIONSCLOSED (options available with INEQUAL) that will work with nonlinear inequalities.

Hello,

I use Maple 11 and I created a procedure (call it MyProcedure), which ends

> display([seq(r||Index, Index=1..NumberOfIterations)],insequence=true);

Futhermore I have a maplet with

> Plotter['PL1']()

and

> Button['BT1']("Draw", width=90, onclick=Evaluate('PL1'=MyProcedure(.....)))

This works ok. Result is displayed in the plotter. However I would like to add other buttons, which will work with this animation. I mean to use functions like Play, Stop, Next Frame, etc. How can I do this?

I need help in solving the following problem.

1-  w1(.03)+w2(.015)=0

2-  w1(1.9)+w2(1.5)=205,000

 

 

Thanks!

Very often I have to insert map(assume,[k,lambda,L,...many others...],real) in order to simplify my expressions.

As a simple example, compare Re(exp(I*k*x)) assuming k::real,x::real; to the result without assuming.

So I'd like a procedure/command that makes Maple assume that every symbol in an expression is real but not the expression itself.
