Hi All,

Thanks for checking out this question. I am working a semi-strange integral and am having trouble getting Maple to evaluate it:

I am getting the response:

"Warning, unable to determine if 464/19 is between 6 and x; try to use assumptions or use the AllSolutions option"

I'm...

I have some numerical data, which are very accurate (500 digits) and want to copy them on a text file.

For pratical reason I would like the procedure writefile to write just 20 digits figures: which is the right syntax to use?

Dear Mapleprimes,

I need to plot a graph for different values of a specific parameter, sigma. It would be great if I could plot them in two separate coordinate systems right next to each other, such that I can copy paste them into my article. Could anyone help me with that?

Cheers,

C

Dear Mapleprimes,

I have a problem with a graph. I need to plot the following:

plot({1/(1-x)}, x=0..2, y=0..4);

But I don't want the vertical line at x=1. How do I get rid of it?

Cheers,

Christian

How it works to be so fast?

Is it somehow related to other wonderful tetralogy:

Hi everyone,

One minor question:

what would be the code to extract data in the form of 2-d points from the output of dsolve/numeric... output=Array/array?

say, I have 6-d ODE system and I wnat to extract data in the form of 2-d arrays of number s and then approximate this with some polynomials via Curve Fitting package.

For this I need the data to be represented as -dim matrices  for every variable.

Thanks for any help.

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:

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...
