## reformulate a function?...

Asked by:
I have a function: fx:=5*x^4+16*x^3-24*x^2 for which to calculate roots I wish to reformulate fx to (x^2)*(5x^2+16x-24) Which command do I need to give maple to obtain this result?? Thanks in advance

## evaluating expressions...

Asked by:
How do I evaluate a result for a certain value for a variable? For example, int(sin(x),x) get me cos(x) in Maple. How do I ask Maple to evaluate cos(x) at , say, x=Pi/8 ? Thanks in advance.

## Plot a triangle?...

Asked by:
Hi, I have plotted the following triangle PLOT(POINTS([(-2,-4)],[(1,3)],[(2,-2)])); How do I get maple to connect these points? Is this the right way to plot a triangle, or is there a better way?? thanks in advance

## importing data and manipulating it...

Asked by:
ok, my first question, and as I only started using maple about 1hr ago, its probably rather a simple solution that I've missed. I'll tell you what i'm trying to do, and what I've tried so far. I've run some code which has given a formatted output of a lot of numerical data, in 4 columns (which I may wish to call x,y,T and P if I can). I wish to import this data into maple, so that I can eventually plot contour plots with it of T on a x and y grid, and P on an x and y grid. Having tried to use the readdata command to read the file in, I got a lot of row vectors. However I then couldn't find out how to reference specific values in these vectors to allow me to assign them to variable values, or maybe just directly plot them. I tried using the importmatrix command to see if that gave anything, but that failed entirely.

## Interface lockup with a fieldplot....

Asked by:
I know I haven't figured out all the limitations of Maple yet to avoid all the "gotcha"s but this should be straightforward, right? with (VectorCalculus): b(x,y,z) := VectorField(

## finding the extremes of a function?...

Asked by:
Hi all, Given two functions f(x)=x^2-1 and g(x)=2x+1 we can plot the following command restart:f:=x^2-1:g:=2*x+1:plot([(f),(g)],x=-2..4,y=-2..8); We have a local extreme of -1. Which command should I use to give me the local extreme where -2 <> 2?? Thanks in advance

## draw a function as a dotted line?...

Asked by:
Hi, Given a function f(x)=x^2 i would type the following command restart:f:=x^2:plot(f,x=-10..10,y=0..10); how do I get the graph to show f(x) as a dotted line?? thanks in advance Robert

## Worksheet auto execute...

Asked by:

Hi to all.. Maybe a beginner's question: How to configure Maple to automatically execute a worksheet as soon as it is loaded? I use Maple 8 on Windows XP and don't want to do Edit/Execute worksheet. Maple is opened via an external batch file. Also, that worksheet produces a graphic file. How to modify the worksheet so that the graphic is automatically saved in a c:\Picture directory after being produced? Thanks for your kind help, Pierre

## Please help...

Asked by:
Hi, I am using Maple to carry out some structural analysis of a beam member. Now, i am facing with a programing problem and I need your help desperately. The beam member being studied can either be in tension or compression. Compressive or tensile reponses are governed by an equilibrium equation and whether or not this equation produces a valid solution. At first, the member is assumed to be in compression and compressive reponses lead to the equilibrium equation. If this equilirium equation does not produce any solutions then the initial assumption is incorrect and the tension case is considered. My problem starts here. I want to make the program switch automatically between compression and tension cases but I dont know how to construct the 'switching criteria' which is " the equilibrium equation does not produce any solution"..So my questions are:

## Few questions about Maplet....

Asked by:
I currently have some MathMLViewers in my maplet and I don't want them to have vertical scroll bar at all times. Does anyone know how to switch vertical scroll bar off for MathMLViewer? Also, is any way that I can have two windows dispaly at same time so I can change window focus by clicking window? Last question, is it possible to display multiple items in ListBox by using Set("ListBox_Name"('value') = blah, blah, blah); Looking forward for your respond, thank you. Tracy

Is there a link to download a demo copy of Maple 10? THanks!!

## Plotting from a data file...

Asked by:
Hi there. I'm trying to make a 3d pointplot by calling an xyz .txt file. It's for a simulation I'm running in Maple, but with results that need to be viewed with gnuplot. It's simply easier to interact with the plot in Maple while I'm still building the code. The data looks something like below (okay, what you see isn't monospaced, so it doesn't line up as nicely as I had in the original post. You get the idea though - first number is x, the next is y, the other is the intensity): (x) (y) (intensity) #these titles aren't actually there 0 0 1 0 1 2 0 2 3

## non-linear equations...

Asked by:
Is it possible for Maple to remove non-linear terms from an equation? I want to use taylors therom on F(V+v, S+s) and get the answer back without its non-linear terms. (N.B. V,S are constants and v,s are variable) cheers gillersuk
