Good day.

I am constructing a 4-set Venn Diagram and I would like to know if it is possible to fix the number of decimal places in the solution.

The attached worksheet is given as an example; the default number of decimal places seems to be 2. I would like this to be either 0 or 1 (for both absolute and relative values). 

Does anyone know how to do this? 

Thanks for reading!

Good afternoon.

I have a differential equation of non-integer degree and would like to know if it is possible to express a solution in terms of elementary or special-functions for certain values of the exponent, n>0.

For this equation, Maple provides an analytical solution for the exponent values n=0 and n=1, otherwise, there is no solution returned. I am particularly interested in the cases where n=1/2, 3/2, 2, 5/2, and 3

I am hoping that someone can help me resolve this - if a closed-form solution is not possible, then a numerical solution would also be welcome.

I have provided the details in the attached worksheet.

Hi. 

I am trying to solve a polynomial equation but the structure leads Maple to return a trivial solution and the other solutions are given as a RootOf expression. The equation involves a single variable, x, that is raised to a power, b and a multiplier, a (both are positive-valued). Please see attached worksheet.

I have not encountered this before and I cannot find a way to get to an explicit solution. Perhaps it is not possible (?).

Does anybody know how to deal with this? 

Thanks in advance ...

Good day, all.

I would like to explore the structure of the discrete modified form of the logistic equation.

In particular, I wish to plot the logistic-map to investigate the bifurcations of the system.

Is there a routine available in Maple that I can use?

I would like to consider the standard logistic equation with the inclusion of a shape parameter, m, introduced as a power law.

That is:

f(x) = a*x*(1-x^m)

where a > 0 denotes the growth rate, and m > 0  is a shape parameter. I wish to fix the value of a and take m to be the bifurcation parameter (so the logistic map would show m versus x for any given a).

Please note: The standard logistic equation (in discrete form) is given by f(x) = a*x*(1-x)

I would be grateful for any advice and support you can provide and I thank you for taking the time to read this.

Hello all.

I am using a k-means cluster routine to partition a set of points into a fixed number of clusters.

The solution assigns points belong to clusters, and this is given in matrix-form. The attached file gives an example of a simple problem that is concerns two clusters (matrices). The entries of each cluster / matrix represent the coordinates of the points in the plane.

I am looking to ..

1. Isolate and label each cluster solution (there may be up to 10), and 

2. For each matrix / cluster, arrange the entries into separate ordered pairs. 

For example, in this instance, I wish to obtain the following form ..

A: = [[-6.08, 52.99], [-7.26, 55.29], [-6.24, 53.29]]

B: = [[-9.72, 51.46], ... , [-9.81, 53.76]]

I have made several attempts to solve for this, but I simply cannot get the solution to output this form.

Any advise / help you can give will be gratefully received.
