How do I mark a value on circles？

I want to plot Smith Chart and calculate the value Correspond to circles.

Any one can give me some suggestions or better idea to plot Smith Chart.

There are my code：Doc1.doc

Hi Maple friends.

x(x+y)^4 = y(3*x-y)^2

When I differentiate implicitly by hand, I get:

-5*x^4-4*x^3*y+3*y^2/x^4-6*x*y+3*y^2 (my lecturer also got this solution)

Maple gives the result as: 

(-2*x(x+y)^3*(D(x))(x+y)+3*y(3*x-y)*(D(y))(3*x-y))/(2*x(x+y)^3*(D(x))(x+y)+y(3*x-y)*(D(y))(3*x-y))

Maybe I am doing something wrong in Maple? From the context menu, I choose implicit differentiation, and then select y as the dependent variable. How can I get Maple to give the same solution?

Thanks in advance.

I have some lengthy formulas in the maple. I don't want to waste time on rewritting them in a word document.
Is there a way to import those equations in a clean and tidy form to a word document or the mathtype program or something else! :)

I've been instructed to create an animation showing the changing plots of a single square waveform using 5,10,20,40,80,160,320, and 640 terms in my Fourier series. This is my code right now: 

with (plots):
L := [seq(2^i, i = 0 .. 6)];

[1, 2, 4, 8, 16, 32, 64]

animate( plot, [2/((2*n-1)*Pi))*sin((2*n-1)*Pi*x], n=L);
Error, `)` unexpected

It doesn't work. Can anyone explain what I'm doing wrong, or how to solve my question?

dualaxisplot(listplot(sols[2], color = red), listplot(sols[1], color = blue), style = line, gridlines = false);

How can I define general matrices in Maple and do symbolic manipulation - for example specifying a matirx M to be of dimension n x m where n and m are integers ?

1-Suppose that after applying the command "factor(f)" the "f "takes the form:

f=(BesselJ(0,r))*(A very lengthy term)

Is there a way to force maple to show f like below:

f=(A very lengthy term)*(BesselJ(0,r))


2-Suppose f is written as follows:

f=a*b*x+a*b*y

Can you suggest a way (without using "op" command) to write f as:

f=a*(b*x+b*y)

Hi Everyone

Is there a built-in way to fit a regression using generalized least squares in Maple ?

Hi,

I am using densityplot function to produce different plots of a function. The function depends on two variables q and yi .

densityplot(f, q = 0 .. 1, yi = 0 .. 1, grid = [100, 100], style = patchnogrid, color = "Red", axes = boxed, axesfont = [Times, Roman, 15], labelfont = [Times, Roman, 15])

I pass the command style = patchnogrid, but still I get these white lines which I believe are grid lines. 
In the example provided in maple tutorial, when they used this command, all gridlines were removed. Why are they not removed in my plots?

if the plot is not visible, click the link

I have used the command "op" in a code that I have written with Maple 17. When I restart the maple server and run the whole code again, the result of the "op" command changes! why is this happening?

Hi all

How can I produce following matrix by maple?

the order of matrix should be {N*(m+1)}*{N*(m+1)} where N is known constant

thanks for any guide

How do you use algcurves and Puiseux series in Maple?

Dear all,

I've a very complicated matrix, and I'm unable to read the result by maple. It should be a 6x6 matrix.

What mean the following expression ?

Thank you for your help.

Phil Yasskin (Texas A&M) has prepared a maplet for the Maplets for Calculus proiect. While this maplet works, in Malmem 18 it sometimes does NOT display the plot. We don't see this behavior in Maple 17, The maplet is attached for your convenience, if you are interested in seeing if it works for you.

The problem is difficult to describe. Basically, at the end of the problem, users can elect to see a plot of the function with(some) asymptotes. The code creates the plot when the problem is created, and displays this plot in the worksheet. But, when the plot is requested within the mapmlet, it sometimes does not show in the empty plot window.

Any explanations (or followup quesitons) will be greatly appreciated.

Doug

Hi,

I read this thread, but it didnt really help.

test.mw （i noticed an error in the expression pj, now fixed!）

See this file above.

The function needs to be maximized is "loglik", with constraints,

f0>0, sigma>0 and mu is FREE. Only three variables.

Using some calculus and by changing variables, I was able to use Gauss–Hermite quadrature, and do some approximation, to get the values:

f0=105.9535

mu=-2.1587

sigma=3.5156

I am wondering if Maple can do this straight away. By that, I mean, without doing much further,  how could I get the values? (most efficiently and quickly)

Thanks,

casper
