Given this equation:       (chi^2*(xi^2-1)^2+1-Omega^2)*(xi^2-Omega^2)-xi^2 = 0

   chi^2=1/1200;  I want to plot xi vs Omega. Can anyone help me out?

Hi!

I am quite new to Maple and have a problem I've been struggling with all day.

I have a spring pendulum and have to develop the equation of motion in the y-direction. The pendulum consist of a mass at the end of a elastic, unbendable and massless rod. 

Please find my Maple-worksheet attached below.

How do I solve the differential equation 2.9 for y(t)? As far as I can see the problem is that I have to differentiate y(t), which is not designated as a function, with respect to y (?)

I would really appriciate if somebody could help me. 

Thank you in advance!

Hi there,

I'm doing my first steps with Maple and am a little confused with a problem:
I want to solve something like

and expect the result to be z=-m*a. However I get empty brackets as result.
I tried to dig a little and I find that maple has problems isolating x1+x2+x3+x4

Error, (in isolate) x1*a+x2*a+x3*a+x4*a does not contain x1+x2+x3+x4

When I isolate it myself Maple even tells me they wouldn't be the same

false

I even reduced the problem to x1*a+x2*a and Maple still has problems with that. As this is a really simple problem I strongly assume the issue lies with the user. Can anyone help me there?

Thanks

Dear 

I need to add animations in a word(.pdf) docuement or a pwerpoint presentation. I Saved my image as .gif and inserted it in my doc but it is an image (no animation)

Thanks

Hi!

I am new to Maple and have a problem I've been struggling with all day.

I have a pendulum and need to find a equation of motion in the y-direction. Please find my code in the picture below.

I can see that my problem starts at Eqy where the differentiation deletes one of the right-hand-side parts because I don't have any function y(t), and Maple thinks y(t) a constant (?)
Can somebody please tell me what I'm doing wrong?

Thank you in advance!

I need create a matrix with 3 dimensions, but I don't know how can I do this. The variable that I need store could be write in this form:

>S[i,j,k];

I don't want write this with subscript but like a matrix. 

I have seen many post with similar question, but I have yet understood how to solve this problem.

I have a contour which maple creates for using command contourplot. 

The problem is that I don't know what is the value of different colors. How can I find out for example what red means?

Is there anyway we can automatically have a color bar with the proper values?

I have Maple 14 on a macbook pro. I recently upgraded to the Yosemite operating system. 

I am trying to use the CurveFitting facility:

with(CurveFitting):

But I get nothing. This might be associated with Yosemite, or maple 14, or ????? Anyone have a guess?

In order to use efficient exponentiation modulo a number n, Maple help recommends using the inert &^ notation in the input, e.g. 5 &^ 1000 mod 29. But when I try to type this input in (default) 2D-Math mode, it interprets the ^ as it usually does for exponents and tries to "raise" the & to the power of 1000. Is there a way to do this correctly in 2D-Math, or do I constantly have to switch over to 1D-Math? I am using Maple 16. 

Hi,

I want to conduct the t- test with a

- null hypothesis of : M1-M2 >= 0

- alternative hypothesis of M1-M2 < 0

I found that I can choose the upper or lower tail option for the alternative hypothesis but I am not sure if the same as I want 

any idea ?

Hi Maple friends.

I created this table using the table component from the componwnts palette. But I can't plot it - Maple just plots the second column as horizontal lines. I want the first column to be the x values, and the second column to be the y values. How can I plot it? 

Also, the table component automatically generates the the incremental values starting from 1, so I only need to create a 1 column table. But how can I plot the table, using the auto generated values?

Thanks in advance.

EDIT: There is a 'embedded plot window' component, which may somehow plot data in the table component, but I can't get it to work. I've tried dragging the table component into it with no succes.

Thanks

Hello!

I'm trying to solve a differential equation of the form y.y"+y'+y= { 1 for 0<x<1 and 0 for else } with conditions: y(0)=0 and y'(0)=1.

I wrote this:

f(x):=heaviside(0)-heaviside(1);

Eq := y(x)*(diff(y(x), x, x))+diff(y(x), x)+y(x)-f(x);

ans := dsolve({Eq, y(0) = 0, (D(y))(0) = 1},numeric);

But it gives an error.

I also tried ODE tools>assistants>analyzer

It says: the ODE system does not contain derivatives of the unknown function heaviside.

It's the first time I use Maple and I don't know what to do. Need your help urgently. Thanks in advance.

Hi all,

I have an expression of the form .

Is there a shorter way to obtain let's say the 5 lowest orders than  ?

Cheers

Hello,

I have been trying to compute the analytical solution of two dimensional diffusion equation with zero neumann boundary conditions (no-flux) in polar coordinates using the solution in Andrei Polyanin's book. When I use 2d Gaussian function as initial condition, i cannot get the result. If I use some nicer function like f(r,phi)=1-r; there is no problem.  

Any idea why this happens? or any suggestion to compute the analytical solution?

Thanks!
