Good Morning,

Would anybody in the community please help me  to trouble shoot the problem with fsolve not producing result.

How do I swap this to a 2 column 10 row matrix.


The topic maybe not so rigor.


For example,here are four complex numbers.

B ={3/13 - (2 I)/13, 3/2 - (5 I)/2, -(7/2) - 13 I, 1 - 3 I}

List B can be easily manipulate like this in mathematica,


In[31]:= Re[A]
Out[31]= {3/13,3/2,-(7/2),1}
In[32]:= Im[A]
Out[32]= {-(2/13),-(5/2),-13,-3}

and in maple,I creat the array like this:

n := (a, b, c, d)

a,b,c,d are the four elements corresponding  to List B above.



how can i find the convergence rate of the sequence:




how can i show that

(1+1/n)^(n+1/2) converges faster than (1+1/n)^n

Hi pro, When i use " maple help " in Maple version 12, I care Christoffel command but I have a question for assistant.

Example (I copy and paste from Maple 12 help):

Dear All

I am evaluating innerproducts between a cartesian basis set with an arbirtary operator, and the result is;

ans = <X|a[11]|X> + <X|a[12]|Y> + <X|a[13]|Z> +

           <Y|a[21]|X> + <Y|a[22]|Y> + <Y|a[23]|Z> +

           <Z|a[31]|X> + <Z|a[32|Y> + <Z|a[33]|Z>

I would like to put this into a matrix form (i.e. removing the bras and kets), so that

Let say that I want two have two inputs nods that each should give a random variable and one node

that simply adds them together and plots the result. How could that be accomplished ?!

proc(x) local t;
 t := x*x*x + 0*2;
 if true then sqrt(t); else t^2 end if;
 end proc;
proc(x) local

in maple 13,the result is

proc (x) local t; t := x*x*x; sqrt(t) end proc

not the simplified proc(x) local t; t := x^3 ; sqrt(t) end proc

 (this is in the reference book)


Hello there, I uploaded a Maple-document with all the information. Please have a look, greetings, Jonas F

Ever since I updated to the latest maple13 patch (for OS X - snowleopard) when I try to call maple from the terminal it hangs: |\^/| Maple 13 (APPLE UNIVERSAL OSX) ._|\| |/|_. Copyright (c) Maplesoft, a division of Waterloo Maple Inc. 2009 \ MAPLE / All rights reserved. Maple is a trademark of


I have the data set and  a systems of ODE ( 2 diff. eqn.)

is there any solution for these two equations simultaneously ?

How can I fit the data and evaluate the constants numerically, and how can I plot this ?

Hi, I am using this code to verify if my function satisfies positiveness / negativeness under assumed ranges or not. assume(`θ_e`, 'real', 0 <><> true then print(b[1]); break else favorableDF_Exists := 1 end if; := '`θ_e`'


although I manage to solve the following problem step by step, I don't really know how translate it properly into Maple code.

First of all, from the following equation I have to extract the derivatives dx/dy1 and dx/dy2 (because I need them later on):


(This can be done using the implicit function theorem).

Then, I have to calculate the following derivate and set it equal to zero to get y1 as a function of y2.

dg1(x,y1)/dy1 = 0
