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'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?

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.

<p>hi,</p>
<p>i tried to write a maple procedure that creates a prefix free tree based on the algorithmen of Shannon-Fano. the theory how the algorithm works is easy but for translating that into a maple procedure causes me headaches.</p>
<p>right now im stuck in the part where i have to split the characters i got until i only have one left. i suppose until that point my procedure might be ok but i how do i continue now? i lack the maple know-how to get further now....and i suppose i did already things wrong because i don't know how to save my nodes</p>

Hello, I'm trying to find a function f(r,r') such that G(r,r')=1/(r-r')+f(r,r'), where r=sqrt((x-x')^2+(y-y')^2+(z-z')^2). I have 6 boundary conditions of the form: G(x,y,a)=0, G(x,y,-a),=0, G(b,y,z)=0, G(-b,y,z)=0, G(x,c,z)=0, G(x,d,z)=0 where a,b,c,d are known constants. How do I do that in maple? Thanks

i need to find real roots for (a*x^3 + x^2  - a*x + 1) as a function of a.

and i need only the REAL roots to show in the output, no imaginaries.

thanks

Hello, I am completly new to Maple and basically any kind of programing at all. I have a project for my Calc 3 class that consists of 5 problems. And I have absolutley no idea how to get any of them done. I have been sitting in the computer lab at school for almost 4 hours and have made very little progress. Anyways, I was wondering if anyone could help with a coulple of these questions to get me going.

 

If i am writing the following code in Maple 11 it gives me the postscript picture with a black frame around.

Why the option noborder is not working?

myPlot1:= plot(sin(x), x= 0..10, axes= boxed, color= black, scaling= constrained, view= [0..10, -5..5]):
plotsetup(
  ps,
  plotoptions= `noborder,width=5cm,height=5cm`,
  plotoutput= "myPlot1.eps"
);
plots[display](myPlot1);
plotsetup(default)

i've read one RNG source code from an article and some of the code are not clear to me. The source code is

proc()

local t;

global seed;

      seed:=irem(a*seed,p);

      t:=seed;

      to concats do seed:=irem(a*seed,p) t:=s*t+seed; end do;

end proc();

 

Hi,

 

I am trying to size a postscript plot in Maple 12.

I don't seem to have any control over the plot size with the width, height, axiswidth, axisheight options.

Is there something I should be doing to get control?

 

Additionally, is there a way to tie these values into the plot export facility?

 

Regards

 

Hi there, I have some .txt files with a large ammount of measuring Data, which i would want to draw in a XY-Graph. It is structured as follows: 1 15.0000 1.120000E+02 2 15.0003 1.460000E+02 3 15.0006 1.140000E+02 4 15.0008 1.340000E+02 5 15.0011 6.600000E+01 6 15.0014 1.100000E+02 7 15.0017 1.370000E+02 8 15.0019 6.000000E+01 9 15.0022 9.200000E+01 10 15.0025 5.200000E+01 and so on, till:
