## sequences with units...

Is it possible to define sequences or lists etc with units?? t:= (seq(100[s]..2000[s],100[s])); and t:=seq(100[s],200[s],300[s]); flag an error. if not is it possible to define the sequence, how can you append the units after a calculation. I want to perform the same calculation using units w/ one of the parameters varying to produces a list of calculated outputs all w/ units. Possible? Easy? e.g. v=d/t simple enough. well how can I generate a series of outputs from the above time sequences at a fixed distance d that spits out the velocities with units of m/s? Thanks,

## Strange !! Maple makes mistakes ! What am I doing ...

Already posted this in my previous thread, but as it is different from the initial topic thought I would post it seperately So I'm playing with integer series and polynoms and it looks like Maple makes mistakes !! What am I doing wrong in below sheet ? View 3284_test2.mw on MapleNet or Download 3284_test2.mw

I am having problems replicating the results from a theoretical physics paper from 1968. The paper deals with how lasers behave in certain material types, in this case nonlinear optical materials. But on to the maths, I'm trying to solve a couple of integrals but it would appear that they are very badly behaved with quite horrid results when i compare the plots to the plots in the paper. I have resorted to using Int to try and solve them numerically which sort of works, but using either numerical or analytic methods maple cannot give an answer for some values of parameters and just sits there for hours trying to solve it.

## Mathematical Modelling of a ships lookout in crows...

hi i am seeking help for a little problem The question is a part of my coursework but it doesnt make sense to me i dont know how to use maple to construct a model can you please help thanks. On board sailing ships or warships, a lookout stood watch in a crows nest high on the main mast. b) Construct a mathematical model to show how far a lookout can see. Clearly indicate any assumptions you make and define any parameters you use in your formula and in the construction of your model. c) You are given that the eye-level of a typical on deck lookout is 1.75m above deck level, the floor of the crow’s nest is 25m above deck level and the deck itself is 5 m above (flat) sea level. The radius of the earth can be taken as 6,3000 kilometres.

## MathMLViewer...

I am creating a maplet application which requires to provide theorems, definitions, and formulas with mathematical symbols. I used MathMLViewer element but it was very unfriendly. Is there any way to control this element to make the statement readable? For example: mu=sqrt(u[1]^2+u[2]^2+u[3]^2); angA:=arcos(u[1]/mu);angB:=arcos(u[2]/mu);angC:=arcos(u[3]/mu); t1:=Magnitude of vector u is*mu*Direction angles are:*A=*angA*, B=*angB*, C=*angC; with(Maplets:-Elements): maplet:=Maplet([[Mathviewer('fonsize'=10,wrapped=true,width=300,height=180,value=MathML-Export(t1))], [Button("OK",Shutdown())]]):Maplets-Display(maplet);

## Newbie question on getting the right form for poly...

Hello there I'm a newbie, both here and to Maple ! :) So I am playing around with some polynoms on integers that I would like to further use in Python programs. Maple is really great to help me get these polynoms, but the problem is that I would like to have them formated in the end with a big numerator over a single denominator, so that python makes the right computations on integers. So for instance, instead of : P(n) = 1/3*n^3 + 1/2*n^2 + 1/6*n I would like to have : P(n) = (2*n^3 + 3*n^2 + 1)/6 (if this is with a big horizontal line of course perfectly ok) Is there a special formating/simplication/transformation function that is available in Maple to get that ?

## International Characters in MapleNet...

I want to display international characters in maplets. For this to work with the MapletViewer I have found that they maplet needs to be saved using the Western (Windows-1252) encoding. (Even this appears to not be entirely perfect, but that is not the issue here.) I have had absolutely no success with MapleNet. The international characters appear differently when the same maplet is launched with MapletViewer and with MapleNet. The two maplets can be viewed from our MapletNet server by visiting the URLs: http://maplenet.math.sc.edu/test/umlaut-1252.html http://maplenet.math.sc.edu/test/umlaut-utf8.html

## plot help...

I have several nut questions. (1) after I installed maple, there are "classical worksheet maple 10" and "maple 10"? Are they different? which should I use? looks the same, but when i do plot and something else, they work differently? (2) about plot: when I plot a figure, there is always a big blank outside frame. And I want get the eps fig without this blank outside frame, can i do it? this outside frame makes the totoal size of this fig large and I could not arrange the eps files in my paper well. W thanks!!

## Exporting Maple Worksheet to LaTeX...

Hello there! I have a maple code that is approximately 300 lines. There are no graphs printed and I would like to export this as a LaTeX code. I choose export under File and save the file as "test.tex" I have installed all the maple packages and refreshed fndb. The problem is that LaTex is not able to run the document. I get the following error: ! Argument of \end has an extra }.

Hello everybody, I'm trying to apply the command allvalues to the output of solve( x^2=cos(x^2), x ): RootOf(_Z^2-RootOf(_Z-cos(_Z)), label = _L4) but when I enter: allvalues(%) I get the following error message under Windows XP SP2: Error, (in @) too many levels of recursion Does anybody know what's going on?
