SmithChart.mw If I want to plot Smith Chart ,how do I mark a circle of arbitrary values?

then,How do I avoid the polar line to cover other circle line?

Any body can give me some ideas or better ways to plot Smith Chart?

Thanks.

V = {(2a + b + c, 3a + b + 2c, 2a + c, b + 7c)|a, b, c ∈ R} forms a subspace of R^4 Show that {(2, 3, 2, 0),(1, 1, 0, 1),(0, 1, 1, 6)} is an (ordered) basis B for V . toally confused on how to do this??..please help!!

Like for instance if I have a formula: ((x^2+y^3)*a1+(x+y^3)*a2)/x^2 and other similar forms as entries for a matrix M, I want to change each entries to a form like this: ((x^2+y^3)/x^2)*a1 + ((x+y^3)/x^2)*a2, what would be the right way to do this?

Thanks for any answers in advance!

any help??

I have been learning to use the Physics package in Maple 18. I just updated to the latest version of the Physics package to see if it would fix the problem by my results are the same.

When I take a covariant derivative in spherical coordinates it does not appear to have a scale factor such as g_kk below.

This definition of comes from the Mathworld web site. I think they have a typo such that it should actually read h_k which is the scale factor instead of g_kk which is the metric. They are related by h_k^2 = g_kk.

Why doesn't Maple's covariant derivative have the scale factor when I am differentiating in spherical coordinates?

Thanks!

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

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?

Hi,

I trying to simulate a force sensor on robot arm, but every time I try something, I get nothing from my sensor, can you help me?

Here it's my "design":

Also, if I add a rigid body I get this error:

Dear Maple experts,

I would like to visualize the equation -3*x+2*y+3*z=0 and (with other color) 2*y+3*z =0. I used the following commands:

with(Student[LinearAlgebra]):infolevel[Student[LinearAlgebra]]:=1:PlanePlot(-3*x+ 2*y + 3*z = 0, [x,y,z], normaloptions=[shape=harpoon], showbasis);

But I do not know how to show at the same time the second equation (2*y+3*z=0 ).

How should I proceed? Any hint?

Thanks for your attention,

Jean-Jaques

I have a great problem with this integral and Maple gives two answers completely different:

so I get two different results :

or this:

In the first integral A get Lommels2 and If I get the Integral by using Taylor of and after that I resum I get Lommels1.

Thank you.

Hi Maple friends.

I am trying to differentiate these:

1. csc(x)/x

2. 3*x^2*cot(x)

From doing it by hand, I am getting:

1. -cosec(x)*(xcot(x) + 1)

2. 6x*cot(x) - 3x^2*cosec^2(x)

But Maple is giving the answer:

1. diff(csc(x)/x, x);

-csc(x)*cot(x)/x-csc(x)/x^2

2. diff(3*x^2*cot(x), x);

6*x*cot(x)+3*x^2*(-1-cot(x)^2)

My answers don't look like Maple's answers. Are they actually the same?

Thanks in advance.

If I use a decimal like 0.569840290998053 into a fraction?

If I have a table of values, how can Maple provide the function?

For example:

x=10,15,20,25,30,35,40

y=2.01,4.87,6.50,9.875,14.00,18.90,24.40

How can Maple find out the y function with respect to x?

How to make Decimal number in maple by default?

How to make radian to degrees? Think It is like this "degcos" but I cant see the correct result, because it is not showed in decimals

Why do I have to active all my varibles when I open the document after I have saved it?
