How do I convert the following trigonometric expression?

->

Hi!

I want to program a specific type of tensor product in to Maple. For two 2x2x2 tensors (hypermatrices)

(A|B) and (C|D), there is a product x defined by equation (2) in the link that yields a 2x2x2x2 tensor

(it would be too difficult to type the product here). If someone

could please let me know how to write a short algorithm that takes as input (A|B) and (C|D) 

and outputs the product (represent it however is most convienent). 

Hi I am writing a program that studies the stability of a dynamical system. I want to sort the eigenvalues of the matrix by magnitude in ascending order and then assign theses eigenvalues to a variable and then check to know those that are outside the unit circle. I am dealing with a 5 by 5 matrix. Do not want to go through  the permuation of thses eigenvalue which is lengthy. can someone help me out. JUS HOW TO ASSIGN EACH EIGENVALUE TO A VARIABLE. THANK YOU

Dear All,

I am trying to find the exact amplitude and phase angle for the signal, with values attached using MATLAB.  BUT the phase angles doesn't make sense.  Can you guys help me in doing the FFT of the signal and find the amplitude and phase using MAPLE.   I am interested in,  fundamental component, 5th , 7th , 11th, 13th 15th, 17th and 19th harmonics with their phases.

I shall be very thankful if anyone of you can actually solve the problem.

I'm looking to create a procedure,Inside:=proc(expr), in maple that takes an expression and will return a direct graph of all the elements,including the operands,of that expression.

For instance for x+2*y*z^2 the output should be (in a graph form not a tree)

                           +
        ...

On Maple 16.02, plattools[transform] only works for very simple procedures. It does not work for procedures with the `if` function even with the simple arrow definition. or with any if-block in a more general proc definition.

With the sequence of commands:

simp:=plot(sin(x), x=0..Pi);
f:=(xx,yy)->`if`(yy > 0, [xx,4*yy], [xx,yy]);
trns:=plottools:-transform(f);
trns(simp);

The first three statements run without error messages. At the last...

I want to simplify the following trigonometric expression

sin(x)*1/2+cos(x)*sqrt(3)/2

to

sin(x+pi/3)

how can I complete this procedure?

Can you confirm that Maple 17 was announced.  I'm thinking that I saw a notice on this.  If so what is the release date?

Thank-you

Please Help me:

First to solve this integration note that it is working if sigma=0.1.

Secondly I want to increase the accuracy of the result of sigma=0.1 as

there is slight difference between this numerical integration and montecarlo simulation 

using MATLAB.

restart;Q := x->0.5*erfc(x/sqrt(2));

sigma := 0.3;

SNR := [seq(1 .. 25, 1)]; for i in SNR do mu := evalf(10^(.1*i));

hello;

i want to rewrite the following matlab code to maple13

L=10*ones(2,m),L(1:2,1)=[90;90];

v(1:2,1:m)=[sum(L(:,1:m)),sum(L(:,1:m))];vv(1,1:m)=v(1;1:m);

this is a piece of program

I need help solving the following:

Plot y=x^2 and its tangent line at x=1, y=2x-1, on the same x-y plane over the following intervals:

a [0,2]

b [0.9,1.1]

c [0.99,1.01]

d Observation

Any help would be appreciated.

Hi,

Presently, I am trying to find a way to replace functional expressions by a variable 

For example I have an expression as follows:

p:=f(x)^2 + g(x)^3 

I would like to get this to look like 

q:= f^2 + g^3 

Does anybody have an idea of how to do this in Maple? 

Thanks,

Willem

Hello everyone!

I'm looking for someone who can write a program for money. I don't know how to write programs in maple language.

I need it as soon as possible.

The task would be to rewrite differential sheme using Thomas algorithm(tridiagonal matrix algorithm).

If you are interested, please write me - gintarewru@gmail.com for details.

If you know any sites where I can share this post, please tell me.

I need some sugestions how to expand terms raised to some exponent within an expression. How to simplify,How to collect terms with some conmon factor within the same expression relativistic_11.mw

Dear All,

I have an implicit function f(x,y) in terms of special functions. I need to optimize it.  So  I plotted it and found the location of the zero slope. However I cannot get the precise value of x and y, where the slope equals  zero.

Is there any better option to get the location of x and y, where the slope is zero?

Thanks in advance.
