Hi,

I have succesfully created a annulus. Because I am creating a garden, I am interested in making circular shrubs in the annulus. I mean an annulus filled with small circles.  How do I do that?

I have this annulus;

display(sector([4.5, -5.5], 2.5 .. 3.5, 0 .. 2*Pi, color = "Green"), axes = none, scaling = constrained)

the radius of the small circles should be: (3.5-2.5=1)

I am trying to write out a code to solve for current in a LRC circuit. I have written a code that I think is capable of doing this but keep getting a recursive assignment message in my for loop. I have looked it over about a hundred times and can't see where I have defined a variable in terms of itself. Any help on this would be greatly appreciated. A copy of my code so far is listed below.

Hey all,

Just started using maple for one of my university courses and am having some problems trying to implicity differentiate a question in one of the problem sheets I have to do.

I am trying to find y' for cos(exp(xy)) = x and the command:

implicitdiff(x = cos(e^xy), y, x)

results in a FAIL. Am I doing something wrong?

Thanks!

Hi,

I'd like to verify the Routh-Hurwitz criteria for a 5th degree polynomial. For the last condition, maple computed the quantity. However when I want to expand (with the commands expand or simplify) this expression (in order to check it sign), maple can no longer display it. In fact Maple calculated the expression but cannot display because when I put a colon in front a the expression, it's okay. So I'm looking a way to display those this result. By the way it's a expression with 43302 terms.

Hi all,

I have this small code as example:

> restart:with(LinearAlgebra):
> e1:=5*x1-x2+6*x3+10*x4-10;

                 e1 := 5 x1 - x2 + 6 x3 + 10 x4 - 10

> e2:=x1-x2+x3-10*x4;

                      e2 := x1 - x2 + x3 - 10 x4

> e3:=2*x1+3*x2-8*x3-x4+20;

Hi,

I need to know how I can obtain a curve with different color. I work with Maple 15

I have a function like this:

Plot (C1, C2, C3, t=1..200, color= red, green, dark)

where C1, C2, C3 are mathematic function and t is the time because these function depend of time.

I need to know where the curve is obtained how can I know that the color green correspond to the second function?

Thanks you in advances.

Hi, I am creating a garden with plan view   in Maple. 

I want to create a train in my garden, so i need to create 1/4 annulus. How do I make that?

Hi, 

How can I create a rectangle in Maple knowing 4 points?

> with(geometry);
> point(A, 0, 0); point(B, 0, -15);
print(`output redirected...`); # input placeholder
                               B
> line(facade, [A, B]);
print(`output redirected...`); # input placeholder
                             facade
> point(C, -3, 0); point(d, -3, -15);
print(`output redirected...`); # input placeholder
                               d
> line(facadepar, [C, d]);
print(`output redirected...`); # input placeholder

I have a HOMEUSE licence including Maple 15, MapleSim 5, with Driveline and Tyre Libraries. Does anyone know when the intergated Maple 16 / MapleSim 6 will be release for upgrade?

Hello all,

I'm trying to solve nine non-linear equations for various input. I am using a for loop to vary the input, and for few input combinations there is no solution. I am trying to exclude these and print the values only if there is a solution. After looking at some of the forms I used if (not type(sol[7], numeric) then print("no solution") else print(sol[7]) end if but this is the output I am getting for all the input.

Attached is the maple...

In it's recent edition of Mathematics Today (in print and online), the UK-based Institute of Mathematics and it's Applications, compared 4 symbolic solvers: Maple 15, Mathcad 15, the student edition of Matlab v5 and the Casio CFX-9970G calculator, concluding that "Maple would be the natural choice for research mathematicians, theortetical physicists, those working in any area where mathematics is demanding or for mathematics undergraduates for whom costs are lower"

Hello, 

I am trying to analyse a nonlinear ode. To see the behaviour,

I am using implicit plot (suggested by @Preben Alsholm).

The problem is that every time I need to search for the value of N

(=infinity) to have some sort of graph (needed for analysis).

The other thing is, if we have an output of the implicitplot, How we can be sure

that it is the correct one?

Hello,

Can anyone help me with this error in Maple while using prcNewton to find local extrema: 

> prcNewton := proc () 

local ftn, strpt, epsilon, maxlps, i, xn, dftn; 

if 4 < nargs then 

elif nargs < 2 then end if; 

if nargs = 2 then 

epsilon := 1/10000000; 

maxlps := 1000 

elif nargs = 3 then
