In the name of God

Dear my friends

Hi

I want to calculate the high-order approximant of taylor series or expansion of f(x) as followings;

g:=taylor(f(x),x=1,60);

g:=expand(f(x));

in which f(x) is a very large expression with respect to x. for example, assume that

f:=x->sum(n*x*sin(n*x),n=1..1000);
g:=taylor(f(x),x=1..60);
Above...

I am working with a 3 dimensional vector partial diff eq that resembles the Helmholtz equation, but there is a curl of the vecotr field as the middle term.

ie-->LaPlacian(F)+2beta*gamma^2*curl(F)+gamma^2*F = 0

Anyone have knowledge or references for me to look over to solve this equation?

Hi, I'm new to Maple and I'm trying to use it in some frequency domain convolutions analysis. At the moment, I'm just tying to organize my work and for this I need to perform some simple variable changes on multiple integrals.

I've started like this: 

> conv:= (x,h,t,tau) -> unapply(int(x(tau)*h(t-tau),tau),t);

> Y[1]:=omega->H(omega)*X(omega);

> with(IntegrationTools):

> Y[2]:=conv(Y[1],Y[1],omega,sigma1);

Hi,

I'm new to Maple.

I'm trying to solve the folllowing systems of equations:

Y= 2x^2-5x+ 3, y= x^3 + 4x -3

However when I try and solve it I dont seem to get a straight answer for X and Y. I've been reading other examples and they all give plain values for x and y.

hello everybody

I need help please

in some forum i found this problem

find a number "abcdefghijklmnopqrstuvwxyzâôîé" with 30 digits if we renverse it

it will be equal 

(éîôâzyxwvutsrqponmlkjihgfedcba)/4

Just a small issue with how you insert a ^ (caret, wedge, circumflex, arrow, hat, what have you), / (forward slash), or * (star, asterisk) as a literal in a comment in Maple.

In regular code, it works fine;

Typing \_ produces _
Typing \^ produces ^
Typing \/ produces /
Typing \* produces *

In a comment, only underscores work as expected.  The caret, asterisk and slash leave behind the escaping backslash, which you will have to go back and delete yourself.

I was writing problems about the bisection method and decided to use the Maple routine Student[NumericalAnalysis][Bisection].  The problem I wrote generates a cubic with all three roots in a somewhat random interval.  Students are then asked to find a root to a given accuracy using the bisection method.  If one does not hit a root, the Student[NumericalAnalysis][Bisection] routine gives the desired answer.

A problem arises when the bisection algorithm...

1. I have a Matrix V as following, and I found that Determinant(V,method=float) can not work. I use Maple12. Please help me , thanks.

2. also, in some calculations, I found Determinant(V,method=float) and Determinant(V,method=minor) gave different result. Anyone can tell me why?And which method is right?

V=[[0.2412702414,0.4868267037+4.770943828 10^(-17) I,-0.3582351644-3.597026404 10^(-14) I,0.8897131421,0.3035225208,0.2809455226],[0.5973344699,-1.205280722,1.019534434+1.083003890 10^(-16...

In a cup run and CuI crystals PbCl2. Did four works of solubility: pKCuI = 11.96, pKCuCl = 6.73, pKPbCl2 = 4.29, pKPbI2 = 8.19. You have 4 unknown concentrations in the solution, but 5 equations (which?). Can you explain what will happen? Documented with calculations.

Recently I was looking at an algorithm in one of Knuth's books.

The algorithm is described in steps with many of the form 

if condition 1 then goto step 7; if condition 2 go to step 8, 

etc.

I managed to write up the algorithm by making each step

a procedure, but had trouble with handling global variables.

Is there in Maple some standard method for dealing with such algorithms.

A friend tells me...

Hey,

I've been running the following program in a maple worksheet and it has worked fine.

Now I want to run it on an Ubuntu machine that has some extra computing power to get through a big data set.

However I get strange "Incomplete Quoted Name" errors, even when I have no quoted names in my input at all.

This is just alittle bit of the output I'm getting:

I'm seeing strange behavior when I try to numerically solve the heat equation with radiative boundary conditions (heat flux proportional to 4th power of surface temperature).  I set up a simple example of a plate that sees 300K on one side and 310K on the other.  Two obvious flaws in the solution of the radiative example are that the slope of the curve always has the wrong sign at the left boundary (sometimes wrong on both boundaries), and that the solution runs away...

I WAS WONDERING IF ANYONE COULD HELP ME OUT... I DOWNLOADED A STRUCTURAL MECHANICS PACKAGE THE OTHER DAY FROM THE MAPLE APPLICATION PAGE.... I KNOW I CAN RUN EACH OF THE DOCUMENTS INDIVIDUALLY BUT I DON'T KNOW HOW TO CALL THEM UP IN THE PROGRAM.. CAN ANYONE GIVE ME STEP BY STEP INSTRUCTIONS OF HOW I CAN INSTALL THE PACKAGE IN MAPLE 13..

THANKS IN ADVANCE!!!

Hi,

I have purchased an e-book for Maple called "Advanced Engineering Mathematics". I have found it to be full of red code text (which I understand to be 1-D Maple format, correct?).

Is there a way of converting the contents of my e-book to get rid of this red text (or at least convert it to something more meaningful) ?

Thanks and regards,

When I write

evalf(Pi);

I get  3.14159...

But, when I want to visualize the value  "e", after writing 

evalf(e);

I get       e .

Why I cannot see the digits of "e"?

Did I instal not properly my Matlab14.0?
