I have already solved my ODEs and used odeplot to analyse the change over time (0 to 10).

Below is my ODE,

d(a(t))/dt = x - y*(a(t))

d(b(t))/dt = m*a - n*(b(t))

My query here is,

I need to substitute a(t) and b(t) in a seperate equation,

h(t) = 60/0.98 * (a(t))*(b(t))

and i need to plot 'h' over time (0 to 10)

How do I go about doing this?

Please help.

Thanks.

Bear with, I'm a noob. This is my code so far:

    > ball := proc (x, y) plots[pointplot]([[x, y]], color = blue, symbol = solidcircle, symbolsize = 20) end proc;

    > animate(ball, [1+sin(t), 1-sin(t)], t = 0 .. 2*Pi, scaling = constrained, frames = 100);

I like the output I have but my aim is to have, say, 8 of these balls, all with their own trajectories, and animated on the same axis. All the trajectories would depend only on one parameter, t.

How to solve attached equation in Maple?

Is there a possiblity to solve using units?

Hello Community,

Wondering if anyone has run into the problem outlined in my code below. I am looking to evalute a commutator involving Pauli spin matrices. One of the matrices is squared. Such a commutator should evaluate to zero. However, the way I implemented it below doesn't give such a simplified result. See Result 7 below. Any suggestions as to how to get Maple to evaluate the exponential before the Commutator? Or to otherwise get to a final, simplified result?

Hello every one,

I have a question about summing data from an ode.

ode:=diff(T(x),x$2)-T(x)^2=0;

I am new to Maple. I need to measure the time complexity of computing the GCD for a set of 1024-bit numbers. I have an equation as:

O(nm × log^2 m × log log m). Where n is the number of bits in the numbers in my set (say, 1024-bit) and m is the number of times I am going to do a computation. How can I perform this computation in Maple ?

does anyone see what i'm doing wrong, trying to solve for n

add(length(i), i = 1 .. n) = 2893;

o/p: Error, unable to execute add

fsolve(sum(length(i), i = 1 .. n) = 2893,n=500..2000);

o/p: n=2893

but if i do a procedure i get the right answer: 

s := 0; for i to 5000 do t := length(i); s := s+t; if s <> 2893 then next else print(i) end if end do;

1000

Start with the numbers 1, 1/2, 1/3, ... , 1/100. Choose any two numbers M and N from this list and replace them by the single number M + N + M x N. Repeat the process until only one number is left.

eq, take pair (1,1/2)-->1+1/2+1*1/2=2

then (2,1/3)-->3 and so on .... and you obtain 100.

Can someone show me procedure to accomplish this, because when i try to do it i get into a tiz

Hi

Can you please let me about the folowing integral in Maple 13

 int(sech(1/2*k*Pi)/(k^2+1)*exp(I*k*x),k=-infinity..infinity);
 Is there any general precedure for finding these kind integrals

Good day, dear Friends!

Hello all,

I'll be straight-forward.

I have Maple 15+MapleSim 5. I don't have Control Design Toolbox. I want to embed a linearized system object as an msys file into MapleSim.

The Linearization template failed to create the file. I tried to use the codes in the template directly as code in Maple, but also failed. Seemingly because I don't have Control Design Toolbox in which the code need to load.

I have been googling around with no avail. I...

I use the eqn feature from Maple to generate troff output.

Each equation is longer than one line.  How does one get the eqn/troff
combination to automatically break the equation into multiple lines.

(I tried finding the division point myself and could not do it.  I am 
generating the output and I have a perl script that puts together the indivdual
equations into the document to be printed.  Thus, I need something automatic)

I tried Google and...

Help !

I have Maple 13 installed on my computer, and when I click the icon in the taskbar, it just sits there and refuses to start.

I tried uninstalling and re-installing it, but that didn't work either. I also installed the latest Java Runtime Environment, all to no avail.

Was wondering if anyone else has had a similar problem, if they fixed it, and if so, how ?

Any help appreciated.

thanks,
Andrew
