First of all, I'm quite new to Maple and here, so I hope you will be patient with me..ehhehe.
I've been struggling some days creating abstract vectorial equations with no luck.
The equations have vectorial components as well as a matrix, it is the equation of motion, i.e:
Inertia * dw/dt + w x Inertia.w = T
Inertia is a matrix that I dont want to define now, and most of all I dont want to spread out its components, so it has to be all the time "Inertia".
w is a angular speed vector and T is the Torque vector.
Neither I want w to be defined or component separated (wx,wy,wz) at this point since I need to work with w for some change of coordinates .i.e w = w1 + ww1 . So I need to work in this abstract level.
The default dot density for exported GIF files is 96 dpi - necessary for screen display but not optimal for printing. Is there anywhere, internal or external to Maple 11, to monkey with the resolution to suit me? (Obviously, I can export GIF and then "alter" resolution in a third party package, but, hopefully obviously as well, this doesn't help as it is very lossy. I need to save the vector content directly to, say, a 200 dpi GIF image).
Also, wmf and eps format exportations are not good options for me either, as these two file export formats fail to reproduce the graph I see on my Maple document: layering gets scrambled, transparency settings are ignored or altered, etc.
I have a question and really appreciate for any input:
- I define an exponential distribution function called f(t)
- Then, I define RP2(t) as a piecewise function of random variable t and some constant parameters.
- I would like to parametrically derive Expected value of RP2. I can easily derive it on paper, given exponential distribution of f(t).
- However, in Maple 10 as its file has been attached, I get the piecewise results without any simplification. Even simplify command yields the same results. I don’t know what I am missing.
Any input is highly appreciated.
Hi.. been using maple v.10 for a few days now.. I created a maple sheet for newton's method of approximation.
The aim was to find F(x) = 0, my final value for Xo was −1.509410457
I wanted to know, how to create a situation where Xo is continuously replaced with Xnew until Xo = Xnew.
Here's my code:
> F(x):=(Xo^5) + 3*((Xo)^2)+1;
> dFx:=5*((Xo)^4) + 6*(Xo);
Xo := -2
F(x) := -19
dFx := 68
> Xnew:=Xo - ((F(x))/dFx);
Xnew := ----
Hello, I am trying to solve this PDE using the Method of Lines and so I turn it into N ODEs. The following is how I plan on solving it;
if (i=1) then "use this stencil (like (Y - Y) / 60*dx);
elif (i=2) then "another stencil";
else "last, general stencil";
I have done a lot of experimenting since my post of 13 hours ago and now have a better handle on the print problem. I am using an HP2110 printer. When I try to print out a document OR work sheet that I originated on maple, I click on file, select print, and on the resulting pop-up menu select properties. There are now 4 choices for print quality: Best, Normal, Everyday, and Fast Draft. If I select "Every Day" the print out will have letters (and graphs) that are twice the size that they should be. Then if I do the same exact thing, without changing anything except selecting one of the other print quality choices, the resulting print out is normal.
Does anyone know how to use "plot" for Piecewise function, wich has to set parametric function (x(t)=..., y(t)=...)?
I'm sorry for my English.
I am using maple 11. I have an HP printer which I verified is working corrrectly. I have a document made in document mode that I stored in a file, and when I print it sometimes it comes out ok and sometimes it comes out with everything about double size and I don't know what I am doing to cause the double size. When this happens I go to file, print preview and click on double page, and then single page at the top and everything seems to print ok in normal size again. But now I just completed another document and tried to print it out and it printed again with about double size letters but when I go to file print preview, double page and single page are not enabled and I don't know why and consequently I have no way to print out this document.
For double-precision ("hardware") real and complex floating-point operations on Matrices, Vectors, and Arrays Maple makes use of its external-calling mechanism to get to compiled code. A great deal of such compiled code for array operations requires what are known as Basic Linear Algebra Subprograms (BLAS). The BLAS libraries provide support not only directly for Matrix-Vector arithmetic but also indirectly in other external compiled libraries used by Statistics, ArrayTools, LinearAlgebra[Modular], etc.
Sometimes when I am browsing this site I have both Maple 10 & 11 open concurrently to see if I get similar results to the various post in both versions. Are there any potential problems in doing this? I am using a Mac (power pc) OS 10.39.
I just created a document for a lab I'm doing and when I went to print preview all the graphs and diagrams I have are chopped off. I just typed everything and spaced it out on the space available to me in Maple (a lot because its widescreen), assuming the edges were the margins like in ms word. But now I can't print without lopping off all my diagrams and squishing everything beyond recognition. Is there a way to format my page or scale everything down to fit?
I can upload the file if need be.
I am trying to plot the same vector field in two coordinates Cartesian and polar. Let's say the field in Cartesian coordinates
Good Morning (Germany anyway ;-) ),
I'm preparing a class room note and want to display a simple algebraic expression _before_ it executes, like:
How can I ask MAPLE to just redisplay it in textbook like manner?
thanks a lot for your help!
In the admirable quest to make Maple better and stronger, and since so few people responded to the Suggestion to add a searchable bug database here on mapleprimes, here's another tack.
What are the fewest keystrokes that can make the TTY commandline interface of Maple 10.06 or 11 crash?
By crash I mean something like bus-error or segmentation-fault, stack-limit-exceeded, or lost-kernel-connection. I don't mean a runaway computation that simply consumes all...
