Good Morning,

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

Regards,

a:=seq(1/x,x=1..10);

b:=evalf(a,4);

c:=matrix(2,10,[[a],[b]]);  

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

The topic maybe not so rigor.

question1:

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,

Re(B),Im(B)

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.

A:=Array([a,b,c,d])

hi

how can i find the convergence rate of the sequence:

(1+1/n)^n

how can i show that

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

In my previous post, I tried to convince you that going parallel is necessary for high performance applications. In this post, I am going to show what makes parallel programming different, and why that makes it harder.

Here are some definitions used in this post:

• process: the operating system level representation of a running executable. Each process has memory that is protected from other processes.
• thread: within a single process each thread represents an independent, concurrent path of execution. Threads within a process share memory.

We think of a function as a series of discrete steps. Lets say a function f, is composed of steps f1, f2, f3... e.g.

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):

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)

I started six month ago with what I though at the time to be a simple question.

Why is the mean in the Black and Scholes model assumed to be (mu-(1/2)*sigma^2)*T ?

I had seen numerous attempts of deriving such an relationship on the Internet but every solution that I found always had some flaw in the step-by-step mathematical logic which meant that the solution was rendered useless.

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 ?

 diff(x(t),t)=a*b*[X(t)^2-(Xo+Yo)*X(t)+X(t)*Y(t)]/[b*X(t)+c*Y(t)];

 diff(Y(t),t)=a*c*[Y(t)^2-(Xo+Yo)*Y(t)-X(t)*Y(t)]/[b*X(t)+c*Y(t)];

data set
