i want to solve this system of equation in analytic way in maple.

sys[Dx(t)+.01(.1x(t)+.1)^2*a+.01*.03*y(t)(1+x(t))*b+.02*.01*c*(z(t)+5)*(x(t)+1)=0,Dy(t)++.01*.03*y(t)(1+x(t))*a+.01*.09*y(t)^2+.01*.06*y(t)*(z(t)+5)c=0,Dz(t)+.02*.01*a*(z(t)+5)*(x(t)+1)++.01*.06*y(t)*(z(t)+5)*b+.01*.04*(z(t)+5)^2*c=0]

in this system a, b,c are costant

Hi there,

I am trying to graph some plots that show Gibb's Phenomenon. I assume that starting with a step function is a good idea.

I know how to plot a step function but I have no idea how to plot the curve that includes the overshoot?

Any help on how to add this to a step function plot would be appreciated greatly.

Thanks you

I consider a polynomial $P(x)$ such that their coefficients are in $\mathbb{Q}(u_1,\cdots,u_k)$ where $u_1,\cdots,u_k$ are complex parameters. I use in Maple the command $galois(p(x),x)$ and I obtain a fixed Galois group solution.  Fortunately, when I give explicit values (randomly chosen) to the $(u_i)_i$, I obtain always the previous group as Galois group. I think that Maple considers that the $(u_i)_i$ satisfy no algebraic equations, that is the $(u_i)_i$ are generic....

Dear all,

I am trying to plot two funtions on one graph, but the axis values differ.  I want to plot the function below with

y-axis starting from 0.284087

x-axis starting from 0

The function is

plot(evalf((A(theta)*B(theta)),theta=0..Pi),  eq A

what to be added in eq A in order the function know that the value of y (axis) should start from 0.284087, and not from zero

Thanks in advance

> F := Int(sqrt((2.138+0.3e-2*exp((4.2^2-z^2)/d^2))^2-2.141^2), z = 0 .. 4.2) = .5;

I have used the fsolve command, it seems like there is a problem.

thank you in advance.

Hello

i have an ode equation which has a variable coefficient n. i solve my ode and the code gave me  single plot for specific n.  i want to draw these plots in one plot the code wich draw plot is :

How do you define v=v(r) in maple? As to say 'v is a function of r'.

Thanks

Dear Maple users

This may be an easy task, but I cannot seem to find out how to do it: How do I get the solutions of an equation on a list form? Let's say the output of the solve command has the reference number (1), then I tried using the convert command and a label to refer to the Maple output, but it didn't work:

convert((1),list)

I hope someone can help me do it.

Regards,

Erik

I'm using matrixplot to plot a matrix 10X10. 

But I want it to be shown only the interval between column 2..6 and row 1..10.

I tried to:

matrixplot(M, row = 1..10, column = 2..6, heights = histogram, axes = boxed) 

But gave error!

***I can not reset the Matrix for 10x5.

To plot the density function of the continuous uniform distribution on [-1,1], my initial attempt was: 

plot(Statistics:-PDF(Statistics:-RandomVariable(Uniform(-1,1)),x), x = -1.1 .. 1.1);

See plot below.


But I wanted something more like the wikipedia image (without the labels, naturally):

See plot below.

In words, I expected a horizontal line on the left of x=-1 and on the right of x=1 (at y=0), and I expected no vertical line at the x=-1 and x=1 points ...

I am generating a number of plots in Maple but would like to be able to collect the data points from the Maple plots and export them into an excel spreadsheet or similar spreadhseet program so that they can be loaded into other plotting software programs such as OriginLab.  

Is there a way to export the data points from plots produced in Maple into an .xls or .dat format?

Here are my codes:

restart;
Delta := proc (beta) options operator, arrow; sqrt(1-1/beta^2) end proc;
T := proc (`&epsilon;`, Z) options operator, arrow; piecewise(`&epsilon;` < Delta(beta) and Delta(beta) < `&epsilon;`, 2*Delta(beta)^2/(`&epsilon;`^2+(Delta(beta)^2-`&epsilon;`^2)*(2*Z^2+1)^2), `&epsilon;` < -Delta(beta) or Delta(beta) < `&epsilon;`, 2*abs(`&epsilon;`)/(abs(`&epsilon;`)+sqrt(`&epsilon;`^2-Delta(beta)^2)*(2*Z^2+1))) end proc;

Hello,

I have an interesting type of IC (alpha*(D@D)(f)(0)+beta*(D@D)(f)(0)^3=f2), but maple

is unable to recognize it. Need assistance in this regard.

Thanks

Hi,

I was just curious if MapleSim has integration capability with Zemax.

I'm interested in creating a dynamic electro-mechanical model (i.e. optical imaging on a moving system):

Zemax <--> MapleSim

If there isn't a toolbox yet, is there a workaround?

Thank you again!
