MaplePrimes Questions

We are trying to obtain an analytical solution of an integral in Maple. When solved numerically the integral converges, but we are not able to get an analytical solution. Any ideas?

The constants in the integral is computed independently, not sure if knowing them can help. The values are r=0.06, kappa=2.6, myksi=2.18, rho=-0.21, stdk=382.2, stds=47.8, kji=52.9 and ksi=62.3. We kind of need the analytical solution to handle the expression in further calculations, and...

how can i overcome the error that i am being given for the problem below 3*t*d(t,x(t),diff(x(t),t))2 = 0

Quick one,

 

How do I count the number of terms in a polynomial

i.e. x^3+x+1 has 3 terms. I have big polynomials with hundreds of time and I want a way to count them

 

Many thanks

HI all,

 

I am trying to figure out in MAPLE how can I write     A * sin*theta + B* cos* theta  in the form as follows:

If (abc‾) and (abcabcabc...abc‾)Ξ0(mod91).Find all non-negative integers (a,b,c)?

To insert a component on your worksheet you need to drag it out with the mouse.  Is there a way to create a slider, for example, on the worksheet without using the mouse?

Hi everyone,

I am trying to build a function of dsolve/numeric solution which would not include procedures for defining the value of it.

First, I need to extract solution as a 2-d array, which will contain all evaluated points of solution.

Next, I want to define a function from this set of points (like interpolation).

Say, I have an array or list of numbers (2-d points).

Now comes the main question: is there a way to interpolate some...

Hi all, i'm trying to generate a sequence of matrices from a matrix with variable coefficients with "seq":

seq(Vector(3, {(1) = 3, (2) = y, (3) = 11-4*y}),y=0..10) 

but it does not seem to work. Do you know why is that, and how can I perform this computation?

Thanks. 

how do you draw a function r=sin(alpha) using animate and "polarplot".

Let (d1): x = 2*t +1, y = t-2, z =-2*t+2 and 

(d2): x = 2-m, y = 3+m,z = 4+m 

be two lines and (P): x - y + z - 6 = 0 be a plane. Write the equation of the line (Delta), knowing that (Delta) parallel to (P) and cuts (d1), (d2) at the points M and N, respectively so that MN = 3*sqrt(6).

Hi,

I have a PDE system that I keep getting the "pdsolve->Warning: System is inconsistent" message.  Is there a way to see where the contradiction is, i.e. where everything is breaking down.  It is fairly complicated and not easy to eyeball such a thing.

Thanks!

HI TO ALL. I M IN THE THEISIS PHASE OF MY MS. I NEED CODES FOR SOLVING A JOB SHOP SCHEDULING PROBLEM USING ANT COLONY OPTIMIZATION (ACO). IF ANY ONE HAS SUCH AN ACO CODE DEVELOPED TO SOLVE ANY TYPE OF JOB SHOP SCHEDULIGN PROBLEM, PLZ PLZ SHARE THAT AT seoccsf7@hotmail.com

 

I WILL BE GREATFUL

Hi, I have a formula with variable unknowns, lets say p,q,r.

How do I get the answer giving me the output for different combination of input that I'm inserting?

For example : f(p,q,r):=(34p9-7q)/r

Calculate when (p=2,q=8,r=7) and (p=3,q=0,r=3) and (p=4,q=1,r=9) and so on...

Please advice. Many thanks

Hi I have a number of 3x3 matrix which i want to combine into one big matrix. But I need to add the end of the first matrix with the start of the second matrix, the end of the second matrix with the start of the third matrix and so on, forming a big diagonal matrix. May I know how can I do that?

for example : my Matrix will need to consist : M111M112M113,M121M122M123,M131M132
