Good day.

Using the iterative map routine, the location of the bifurcation points of the logistic function can be determined using the plot (see attached).

I was wondering .. is it possible to estimate and output the locations of these points and the range of the function? I would like to explore the bifurcation behavior for the modified function so, this would be a great help. 

In this case, the location of the points are: (1.00,0.00), (3.00, 0.66), (3.45, 0.44), (3.45, 0.85) and the range is [0,4].

Good day.

I am looking into the behaviour of a function, V, that depends on several parameter values; these values are fixed in the attached example. However, I have encountered an issue that is puzzling me and I was hoping that someone may be able to shine a light on this for me.

Basically,  I would like to understand how the solution, V, behaves as the value of exponent, beta, approaches infinity.

Straightforward analysis suggests that the value of V tends to -10 as beta grows infinitely large (s -> C, and beta ->infinity and so, V -> -10 ... so far, so good).

However, when the function is plotted, the solution seems to converge to a value, 6.5, as beta tends to a very large number (10^17).

Now .. here's the mystery .. there appears to be a critical value of around 7.854 x 10^17; here, the limit seems to switch from V=6.5 to -10. Does this phenomenon correspond to a discontinuity or is it related to the computational process? Are there any built-in routines in Maple to check for such potential conditions?

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?

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 ...
