I want maple to calculate sqrt(Pi) with an accuracy of (10)^-200 with Newton Raphsons method. How do I do?



The surface in above image is a portion of the graph of
some mathematical equation.

Let's do some brainstorming:
Can you guess what's inside the surface?

as you know the number of solutions for order 3 to 5 magic squares is as follow : 
(not counting rotations and reflections)

order 3: 1 solution

order 4: 880 solutions

order 5: 275305224 solutions

higher order: unknown ...


in the first look at 880 , simply appeared it can constructed by
2x5x8x11 (every factor increased by 3)

Hello! Anybody can help my to have this problem?


A^2+3*A+Delta*I = 0;

 A = RTABLE(145776372,MATRIX([[a, 2], [1, b]]),Matrix)

I want calculate 'a' and 'b' whit 'x' and 'y', and it's my code:



But this is wrong, but I dont know...

Thank you!!!!

(sorry for my English)

int(sqrt(1 + sec(x)^2), x)

int(sqrt(2 + tan(x)^2), x)

With Maple 13, which is the latest version on the computer on which I tested these integrals (that originated with a

senior scientist in Australia), the former yields a reasonably compact answer, but the latter yields an extensive

output containing Elliptic functions of various kinds.  The two integrands are trigonometric identities.  What is the

problem here?


      Here is one of the problems from "Mathematical Trivium"  (Russian Mathematical Surveys, 1991, 46:1, 271-278) by V. Arnold. Those problems are aimed at the strong graduate and postgraduate students of the top universities.
      I find it remarkable that a big part of the Arnold's problems can be solved with Maple.

I will use this post for a list of conclusions drawn from MRB constant N and the many similar approximations that I have found. 

Let x= MRB Constant.   Each approximation is followed by a maple input so you can verify these approximations. 

I want one of a sequence of questions to not show it answer. The other questions need to show their answers, but this one

cannot. I could make a separate assignment for this question but that seems rather painful. I use latex => .qu so the

solutions that don't require touching the editor is a plus.

I'm doing some algebra with transfer functions, which are often written in LaPlace Transform notation, e.g. f(s) = 1/s.  One often wants to find the "gain and phase" of such, which is easy to do using the following steps:

1) Substitute "i omega" (imaginary unit, omega = frequency in radians) for s.

2) Express the complex quantity in polar (rho, phi) notation -- rho = amplitude, phi = argument (Phase).

So here's my question -- if I am developing...

Ok hello everyone and thank you in advance.
I have 2-3 difficulties in a maple plotting.
I'm trying to plot two fairly easy surfaces in maple 3d
What I want is:
3 standard axis, x,y,z with y vertical and z coming out of the screen(obviously you can turn it and stuff.)

Two surfaces:
On with y = (1/x), z=free;
The second with y= 2*x(1/z);

Hi all,

I'm editing a scientific document in Maple document mode. I'd like to assign a mathematical result to a variable, which is a 2D-math expression.

An example:

I'd like to assign the result of


to the expression

I was about to post this as a "How-do-I" question, but while composing my question, I stumbled upon the solution.  In case this "discovery" would be useful, I'm posting it here.

For some coursework, I'm developing fitting sinusoids to experimental data (poor-man's Fourier Analysis).  At one point, I do a "brute-force-least-squares" computation, one step of which involves computing the sum of a sine over N equally-spaced intervals around the circle.  This...

As some of you know, I'm hoping to, some day, find a closed form expression for the MRB constant.

 Here is my latest little nugget.

Let x=MRB constant.

(1-604*x)/(28+209*x) = log(x) with an error< ...

Why does:

G := Heaviside(x): int(G(x)*G(t-x), x = 0 .. 3);

Produce a "Error, (in unknown) too many levels of recursion"?
