HI,

I am trying to solve for fourier coefficients but can't figure out the error in the code. Need help to debug the code.

Also if possible how to find the harmonics in the curve defined in the code.

following is the website from where i got this code

http://www.mapleprimes.com/questions/121551-Fourier-Serie-And-Discrete-Fourier-Transform

fouriercoefficient_h.mw

Here is a simple version of the code:

restart;
plots[textplot]([4,2,q[n]]);
plotsetup(gif,plotoutput=`p.gif`);
plots[textplot]([4,2,q[n]]);
plotsetup(default);

I am trying to write a quaternion package, I also want it to be able to multiply quaternion polynomials where the unknown "x" remains on the right of the coefficient. the I,J,K rules are standard quaternion rules.

define(M, 'flat', 'multilinear', 'identity' = 1,
M(I,I)=-1, M(J,J)=-1, M(K,K)=-1, M(I,J)=K, M(J,I)=-K, M(J,K)=I, M(K,J)=-I, M(I,K)=-J, M(K,I)=J,
M(a::anything,b::anything*x)=M(a,b)*x,
M(a::anything*x,b::anything)=M(a,b)*x,...

Hi everyone,

 Is there any possibility to add two plots together and have the wave shape which will be combination of the two.

Equation for two plots is attached.     help.mw

Thanks in advance

Dear Maple Users

I am looking for specific answer, please see the following code,

by trial and error I estimated proper values for 4 parameters, and corresponding equations become close to zero.

However I need to make it automatically via maple, what can I do?

If I give ranges for parameters, there is no answer existed.

Thank you.

you can download worksheet from the below:

hi

i write following code that solve ordinary differential equation. but its not good enough. because when in loop it want to integrate equation it takes too long for many problems. i wants you to help me to solve this problem. i think maybe its better to solve with numerical but i cant. its really important for me and thancks for your help. I bold that section.

restart:
equ:=diff(u[i](x),x$3)+(1/2)*diff(u[i](x),x$2)*u[i](x)+(2*m1/(m1+1))*(1-diff(u[i](x),x$1)^2):

Hello, I need some help on how to solve this eq: diff(y(x),x,x)-y^2=0; y(0)=100,y(2)=1 When I tried to do this by solve command, I get a blank list. I really need help on this. thanks a lot

I wrote a quaternion package, defined my own `*` and etc.

now I multiply two matrices using MatrixMatrixMultiply.

and I obtain something like this, notice it's not simplified, with terms like (2+K)(4+I):

however, if i simply highlight what's shown above(the output) and copy and paste it and then press enter, i get a simplified version (it still doesn't simplify `^` but that can wait)

HI,

I am struggling with simple multiplication shown in the attached file:

Is there any specific multiplication command I should use. 

Pls guide me in respect of how to make plot after multiplying A and B

Thanks in advance

Both Interactive stock quote importer applications in the application center are for Maple 13 and Maple 15.

Can anyone help to get it to work in Maple 12?  Does the Maple 13 code still work today?

The error I recieve running it in Maple 12 is, Error in Component Button0 with caption "Get finance Data from Yahoo" (in assign) invalid arguments.

Hello!

I am a student and totally new to MapleSim. Unfortunately I have some difficulties to solve the tasks my boss is giving me. Maybe you can give me a hint. I am working with MapleSim 4 and Maple 14.

My task is to create a system of four masses, that are connected by springs and dampers that have translational and rotational properties. So far, I build the system and I was able to connect the masses with translational springs. Here my question: How can you...

Below is the command I was trying to use to solve the set of equations. It doesn't give me an error or a result, I'm not sure if I am using it wrong or if solve is just the wrong command to use. Any advice would be greatly appreciated.

solve({beta*(chi^2*(exp(delta*rho))^2*delta^2-(1-chi*exp(delta*rho))*chi*exp(delta*rho)*delta^2) = 0.4e-1, beta*(-(1/12)*chi*exp(delta*rho)*delta^4*(1-chi*exp(delta*rho))+(7/12)*chi^2*(exp(delta*rho))^2*delta^4) = 0.8e-3, beta8*(-chi^2*(exp(delta*rho...

 I want to find the Christoffel symbols and Ricci tensors for a generalized metric in cartesian coordinates.

I stated my problem in this pdf file in detail.

Thanks in advance.

PS: I heard from somebody(doesn't use Maple) that Maxima can "certainly"...

Good afternoon

i have problem when i am using components.

i want to solve a determinant equation and show in MathContainer4

thank you for your help

Hi, this may be a stupid question, but I have trouble getting it right...

I want to create a matrix from a function that uses some of the arguments of the fuction as indices, but want to carry on the other arguments, here is an example of what I have:

MyFunction:=(a,b,c,k,l)->a+b+c+k+l;

MyMatrix:=Matrix(3,3,(k,l)->MyFunction(a,b,c,k,l)); # this is working but not what I want

MyMatrix now contains a,b,c as variables but not as function parameters ...
