Hi All,

I was wondering if anybody could help me figure out how to find the closed form solution to a PDE, specifically the consolidation equation: dq/dz=C*d/dz(dq/dz).  I have a set of BCs but that is unimportant for now.

I would like the solution as a fourier series, but i'm new to maple and am not sure how to do this.  If anybody has a file set up to obtain the fourier series solution for a PDE and could post it, that would be a big help.

Thanks.

I want to prove by Maple if  -1<x<1 and n is positive integer then

sum(k^n*x^k, k = 1 .. infinity) = (sum([sum((-1)^(m+1)*(binomial(n+1, m-1))(r-m+1)^n, m = 1 .. r)]*x^r, r = 1 .. n))/(1-x)^(n+1)

I would appreciate for any help.

Dear all:

    I am wondering if there is any way in Maple to add properties to elementary functions? For example, both

is(sin(x),continuous) assuming x::real;

and

is(sin(x),monotonic) assuming x>0 and x<Pi/2;

fail. More specifically, how to tell Maple that sin(x) is continuous and monotonic if  k*Pi <= x <= k*Pi + Pi/2 ?

Another question is that I am not very sure how to use the monotonic property, i.e how it can be used to simplify your expression? Can someone give me an example?

Thanks,

1. How do I take a 2xN matrix and plot it on a 2D graph by its columns?

2.How do I take a number n and a 2xN matrix and return the product of A^n with the 2xN matrix, where A is a 2x2 matrix?

3.How do I, using your two functions above, write a procedure which plots on the same graph the result of multiplying the 2xN matrix by A^n for n = 0,1,2..10. How do i cause these sequence of plots to be displayed as an animation?

Hi

Is there any way to type maple code in an alternative editor and then run it directly in maple? I find the editor in maple a bit of a mess. Particularly the indents, I can only seem to indent by a very large tab and then if code spills over into the next line it starts at column 1 again making for very difficult to read code.

Any suggestions for either linking an alternative editor with maple or improving the indent situation in maple would be very useful.

Thanks

 

I want plot this abs error function

with two variable, I set

x:=-0..2;

plot(abs(sin(x*w)-cos(x*w),w=-2..2));

 

But it is not displsy. Why ,Can you tell me about how to

plot the figure.

In my previous post, I was parsing data out of HTML tables so that I could glean some trivia from it.  My true goal was to compile data out of dozens of such tables and so I needed a way to do the whole process in Maple.   So, now, here is how I used Sockets and StringTools to automate the whole process.

I installed Maple 12 under windows XP. The machine satisfies the hardware requirements given in the documentation. Activation was confirmed.

On startup, the welcome screen appears. After entering the document/worksheet window, it stalls. CPU usage is close to 100%. I waited about 30 mins and had to kill the application.

Maple classic and command line maple work fine.

On this machine I previously had Maple 11 installed, with the same problem.

I'm using maple 11, and I need help changing the axis variable to something other than x vs y.

For example, I want to graph  y= 1+x(2x^2 +3) ^ (1/2)

by changing the eq to ((y-1)/x)^2= 2x^2 +3

and plotting ((y-1)/x)^x  vs x^2 I can obtain a straight line.

How can I change the axis to this instead of  x vs. y

Obviously I'll be using with(plots, implicitplot);

 

I'd like to use the Del operator in the form (A.Del)B, where A and B are vector fields. In Cartesian coordinates this is (Ax d/dx + Ay d/dy + Az d/dz)(Bx ex + By ey + Bz ez), but in other coordinate systems (which are the ones I want to use) it's much more complicated. Is there a way to use the Del operator in this form? (ex, etc. are unit vectors)

Hi, I want to plot a set of complex numbers which have the property: |z-1|/|z+1| < 2

I should get a circle but plot() only uses real numbers.

How do I? ;)

Recently there was some discussion in the Maplesoft office about unisex baby names (that is, names that nearly as likely to belong to males as females). Whenever discussing names, I usually head to the US Social Security Administration's wonderful baby names site. They have data on the top 1000 male and female names for children born in the US each year for more than the last century (that includes about 80% of names). They slice the data a little by US state, and popular names for twins and such, but they do not include data on unisex names. So, I applied Maple to the task.
