I'm trying to construct an iterative procedure NR1(f,x0,N) where f is a function, x0 is an initial estimate (which can be complex) and N the number of iterates.

Given:  x_k+1=x_k - f(x_k)/f'(x_k), k=0,1,2....,

Now for example by defining f:= x-> x^2-2 and inputting x₀=1 and N=10 i should be able to check that my procedure calculates sqrt(2) correctly.

This is what i've got so far.....

HI2all! I use c++ builder 5.0 to create interface for maple code.At first I tried to start example from openmaple help topics. I have copied example and have inserted it to console wizard of c++ builder. Copy header files to work directory... At first i received(for strings of .h files: INTEGER64 int64;): [C++ Error] mpltable.h(239): E2176 Too many types in declaration [C++ Error] mplshlib.h(148): E2176 Too many types in declaration [C++ Error] mplshlib.h(210): E2176 Too many types in declaration [C++ Error] maplec.h(266): E2176 Too many types in declaration

I am having problems using implicitplot.  I run this code and it worked and today I tried it again and it gives me the following:

with(plots,implicitplot);

implicitplot(0=int(erf(  (T-e*t)/sqrt(2)  )*t^2*exp(-t/2),t=0..infinity),e=0..1,T=0..10);

Error, (in plots/implicitplot) invalid input: the following extra unknowns were found in the input expression: {t}

The weird thing is that this worked before (took about 10min though) and now it isn't.  Any suggestions?

Thanks

Has anyone implemented https for Maple T.A. 3.01? Mainly we are looking to secure the login and password information, but if everything must use ssl, that's ok. Thanks.

Can anyone help with number 12.2.5?

 

thanks,

very respectfully,

 

 

 

We are looking to use TA.  Our Uni common authentication system uses Apache/Kerberos.  Is there a way of getting TA to use the Apache-supplied authenticated username?  

The documentation seems to suggest the only options are TA's internal user/pw system (where I saw something that suggests the p/words are held in plain text(!)) or an LDAP server.

Grateful, as always,  for any insight.

Obtain Hamilton's equations of motion for a plane pendulum of length l with mass poin m whose radius of suspension rotates uniformly on the circumference of a vertical circle of radius a.  Describe physically the nature of the canonical momentum and the Hamiltonian.

 

v/r,

Thanks,

 

I know this is a mathematics forum, but I think that there are many faculty members and others here directly or indirectly affiliated with physics.

Again from Goldstein's, "Classical Mechanics" Chapter 8, The Hamilton Equations Of Motion.

The question is:

Write the problem of central force motion of two mass points in Hamiltonian formulation, eliminating the cyclic variables, and reducing the problem to quadratures.

Hey

How would i go about modelling the Least Square Fitting Approach in maple?

I am concentrating on a 3x3 to a 5x5 grid rather than infinate.

the formula is

y = C  + Dt

I know the least fitting approach then goes into inversiting the matrix, or something, but i dont understand the math model which is why i want to model it in Maple.

Thanks for any help

To Maplet Experts:
There is dearth of work  on ComboBox, a maplet element.  How does one access an item in a ComboBox.  How does one know which item in the itemlist is selected.  How does one pass selected item as an argument in a function,
I will appreciate any respond to these questions.

Hi

I'm currently trying to write a matrix question. My problem is that the answer can take to forms. I can use a maple graded question to exect both answers but am having trouble when it comes to using a 'matrix; type question. It there a way to get the matrix question to accep the both answers or has it got to be done with a maple graded question.

Regards

Dear all,

I would like to solve the following equation (linearized Poisson-Boltzmann in 2D) in Maple:

diff(u(x,y),x,x)+diff(u(x,y),y,y)-k^2*u(x,y)=0;

subject to the boundary condition:

u(x,a*cos(bx))=0 and  u(x,y)|y->infinity=0

(a,b and k are parameters)

I succeed to get the solution with pdsolve, my problem is how to solve the boundary condition problem.

Thanks!

 

A link to a Maple10 worksheet is attached below.  The worksheet has the command lines but has not been executed so it size came under the limit for uploading.  The worksheet is an effort to animate the radius vector to a spacecurve complete with the tangent vector and associated normal and binormal vectors.  Early in the worksheet we suceed in animating the radius vector and the spacecurve.  This success was achieved with some pain.  For instance errors with the plot structures na ddisplay command would not work unless the whole sheet was executed - if, after this,
