Hi all, I'm not good at maple, so need a help from experts. I'm using Maple v.12. -part of the code- ... de2:= # Nonlinear DE is here # ics:= X(0) = 1, (D(X))(0) = 1; sol:= dsolve({de2, ics}, numeric, method = rkf45); (or sol := dsolve({de2, ics}, x(t), numeric, stiff = true, range = 0 .. 200);) Error, (in f) unable to store '1.0000000024691*{1.}^2+2000010000.' when datatype=float[8] -end of the code- As you see above, It's a simple process to solve DE. so most of the DE, like (1) below, is solved very well through the code. But my case is (2). I could see error msg as you see above.

Good day, I cannot run this maple, why?

I need help!

I'm trying to plot a sphere, and then shade-in the bottom one-third of it.  Is that possible?

Also, I then need to plot a sphere with 8 approximating disks.

Does anyone have any ideas of how to do these?

I have a Matrix O[n,m]:=Value with n:=1..10 and m:=1..10 How can I present the values in a 3D plot with x->n Y->m and Z->Value. One time I want to make a histogramm out of it and in a second case just connect them to a surface How can I do that Thank you very much in advance!

Hi,

have a look at this plot, i'm using standard worksheet (in classic this problem doesn't exist). 

plot(sin(x),x=-5..5,tickmarks=[default,20]);

Instead of -for example- 0,5 i want decimal points 0.5

Playing with the tickmarks option would do the trick, but a "global switch" would be better.

What to do ?

Hello everybody, I was wondering, is there a way to call procedures from a different worksheet? I am writing a big procedure which calls many smaller ones and that would be really clearer if I keep them in a different worksheet.. Thanks a lot in advance..

Hi, I have a polynomial expression like this:

2*a^32*b^3 + 3*c^2*a^3 + 4*a^5*c^2

I would like to apply rules like these ones:

a = a^x and b = b^y,  ∀ x,y ∈ N*

It should result:

2*a*b + 7*c^2*a

I would do this manually, but I intend to use this to really big expressions and it would be quite boring. Any ideas?

 

Thanks in advance and sorry the english,

Dear experts, I want to plot a matrix with B[n,m] and n:=1..10 and m:=1..10 The problem is that the plots achses are labled with n and m. I want to lable the achses with N:=0.25 to 2.5 in steps of 2.5.... How can I do that?

Hello everybody, I am a bit stuck here because I have the problem above, any help would be really appreciated.. E1:={{0,2},{0,7},{0,a},{0,b},{1,3},{1,8},{1,9},{1,a},{1,e},{2,3},{2,a},{2,d},{2,e},{3,4},{3,6},{4,8},{5,7},{5,a}, {5,e},{6,c},{6,e},{7,8},{7,a},{7,e},{8,b},{9,a},{a,c},{c,d},{c,e},{e,f}}; for e in E1 do e; end do; {0, 2} {0, 7} {0, a} {0, b} {1, 3}

Hello everybody, I have a question, any help would be really appreciated. Let me illustrate my problem with a small example. Say I want to define 1000 variables like this: x_1:=1; x_2:=2; x_3:=3; .... x_1000:=1000; That would be very tedious to be done by habd so I would like to use a 'for' to do that.. Is that possible? The code below does not work: for i from 1 to 1000 do x_i := i ; end do; Any ideas? Thanks a lot in advance..

Hi all!

So I have an equation like so:

I have to plot a graph of the resistance against variable frequency of up to 1Ghz.

So I am plotting for frequencies 1Hz, 1x10^2, ... 1x10^9

Question is, how do I use Maple to input a set of frequencies into f of the above equation, giving out the resistance, and then plot a graph.

I am new to maple.

Thanks in advanced.

Dear experts, I wrote the follwing loop. Unfortunately it is very slow. The procedure Powell takes only 5 seconds in a single case, but in this coonglomerate of loops it takes much longer. Do you see a way "to make it faster"? with(LinearAlgebra); S1 := .1; S2 := .1; for n to 10 do for m to 10 do S1:= S1+.2; for m to 10 do S2 := S2i+.2; w := proc (Q1, Q2) -->evalf function.... if (Zwischenspeicher[1] >= 100, Zwischenspeicher[2] >= 100) then B[n, m] := 1 end if; if (Zwischenspeicher[1] >= 100, Zwischenspeicher[2]

Hi

How do I generate Pascal's Triangle in Maple

I am studying Computer Science. I know how to generate Pascal's Triangle In Java.

I am still learning Maple.

Here is my Java Code

import java.applet.*;
import java.awt.*;
import java.io.*;

public class PascalTriangle extends Applet {
  TextField ROW;
  TextArea DISPLAY;

  public static void main(String args[]) {
    PascalTriangle pt = new PascalTriangle();
