I know that the purpose of Maple is not to be a typesetting worksheet. But the improved typesetting abilities (Ver 10) are useful for making demonstration worksheet. Specifically, I would like to make a demonstration worksheet of a mark-recapture model I am currently working on. The main purpose is show how how the likelihood is built, step by step, following the paper's notation. As well as showing estimable parameters (including sparse data scenarios). Since my work is used by biologists rather than mathematicians, I feel it is a worth pursuit. The only problem is that I cannot dupicate notation such as:

I have still been using mostly release 8, but was wondering whether MAPLE 10 now can do things standard in MATLAB, JAVA: Is there a way in release 10 (maybe via maplets?) to use the mouse for extract the coordinates of a point from a maple-plot [[ e.g. want to use initialize a dsolve() by graphically selecting the initil data.]] going further, is there a way to "draw" a curve on a maple plot using the mouse -- and get the coordinates of points along the curve back into the worksheet )(e.g. as an array that can be further manipulated)?

Greetings, I have done some searching and have been unable to find out how to use complex numbers in polar form in Maple 10. Is this possible? If so, what about degrees versus radians and can both polar and rectangular representations be used in the same document/worksheet? Thanks, Ken

I am having problems with subs and collect. Unfortunately, I still haven't figered out how to make the input part of a MAPLE equation visible in the post. I still have the problem that it just appears as "MAPLE equation" so anyone who is kind enough to want to help me will have to look at my file Thank you View 2292_SubstitutionAndCollect.mw on MapleNet or Download 2292_SubstitutionAndCollect.mw

I would like to apply a relation such as f(x,a)*f(x,b) = (f(x,a)+f(x,b))/c (where x,a,b are any real number say) to simplify an expression such as f(y1,a1)*f(y2,a2)*a3*f(y1,a4)*f(y2,a5) to a3*( f(y1,a1)+f(y1,a4) )*( f(y2,a2)+f(y2,a5) )/c/c The only way I can see to do this is to struggle to get the function in the `right' order with no constants between them, and then do a substitution for every variable triple (y1,a1,a2) that occurs. There must be a better way. I've looked around the forums but I don't even know what to look for really so any suggestions of where to look would be great.

Hi - Is there a way to tell Maple to zero out terms in an expression that have a very small constant. For example I would like to round something like (1x + 2y - (1x10^-20)z) to (1x + 2y). Thanks. Bryan

Hereby I'm telling you I'm new in using Maple, so please don't laugh after reading my problem. I want to plot the function x=6. In my brain this is a vertical line, through the x-axis with x=6. After several attempts, the only thing I get is a horizontal line through y=6. Where did I go wrong? > x:=6; > plot(x);

May be a bit off that forum, but may be somebody has an answer or some reference: for the linear transforms w = 1 - z and w = 1/z there are exceptional cases given the formulae in Abramowitz & et al do involve infinite series in Psi (A&S 15.3.11 ff). A direct coding becomes slow and it is awesome to dig through Maple's code for that. Does there exist s.th. worth to look into it (please no pure source code like Macsyma or so ...) ?

(D@@2)(x)(t)=(-g/v)*sqrt(D(x)(t)^2+D(y)(t)^2)*D(x)(t)
(D@@2)(x)(t)=g-g/v*sqrt(D(x)(t)^2+D(y)(t)^2)*D(y)(t)
initial conditions
x(0)=0,y(0)=0,d(x)(0)=134,d(y)(0)=0
using rkf45
for time, 0-30
solve for x(t),y(t)
then i plan to plot the two and find the intersection
but i'm having trouble getting through the rkf45 to get my x(t) and y(t)

Is it possible to have MapleNet generate pretty-printed math formulas as images, or does it require the user to have a browser that can render MathML?

For instance, in the integration.jsp demo I can use


<maple:statement type="text">doInt()</maple:statement>


to print out

-4/17*cos(4*x)*exp(-x)-1/17*sin(4*x)*exp(-x)

But what if I wanted that pretty-printed, and I was on a browser that didn't support MathML. Is there any way I could do that?

I intended to post this msg in this forum but somehow put into the MAPLE TA forum. Here it is where it belongs. I know this is a really basic question & I'm kind of surprised I haven't run into this situation before, but here goes. Multiple assignments are possible, e. g. a,b,c = 1,2,3 What's the simplest MAPLE command(s) which will place into each of these 3 variables a value twice its previous value. I try stuff like a,b,c = map(x->2*x,(a,b,c)) and MAPLE says no way!

how do i solve a set of coupled differential equations like these for x(t) and y(t) eqn1 := (D,2)(x)(t) = -a*sqrt(D(x)(t)^2+D(y)(t)^2)*D(x)(t), eqn2 := (D,2)(y)(t) = g-a*sqrt(D(x)(t)^2+D(y)(t)^2)*D(y)(t)

Hi, Im using the display command to plot 3d surefaces/projections (which the also overlap on different occasions)on the same graph coming from different equations. My question is how can i colour the surfaces with a command (its too hard to do it onthe graph)so i know to which equation each surface corresponds to? Is there an additional way offered from maple to distinuish the graphs from each other. Finaly, I use the command labels=[x,y,z] to call my axis "Time of Fault Clearance,s" , "Magnitude of Fault Current" , "Parametr".How do i syntax a string? Thanks for your time

Below is the code I'm trying to get working. In matlab this would be cake, but I can't seem to figure out how to get this working in Maple. Help Please.... > for j from 1 by 1 to 6 (for n by 1 to 6 do M[j,n]:=(∫)[o]^(l)(phi)[j]*(phi)[n]*p ⅆx end) end do; Error, invalid sequence for j from 1 by 1 to 6 (Typesetting:-mambiguous(for , Typesetting:-merror( Ok I also can't get my code to past in..... urgh...

Hi, I am having a problem with making all of my worksheets appear as tabs. Maple only displays a worksheet and then I have to use the back or forward arrows or the "more" windosw pull down to activate a sheet. I have had all the worksheets appear as tabs above the worksheet before, but cannot figure out how I did this. I am using Student Maple 10. Can anyone tell me how to make them appear as tabs? I have check what I think is the appropriate box.. open worksheets in new tab. TIA Larry Ciak aka malt_master@comcast.net
