SOME ONE PLEASE HELP ME WITH MY DAMM ALGERBRA I DONT GET IT WELL YEA SOME ONE THNKS .

The following returns 0, which seems less than ideal to me: assume(m::integer,n::integer); int( cos(m*x) * cos(n*x) , x = 0..2*Pi ); Is this intentional or unavoidable - or is it something that could usefully be improved? Toby

Why can't maple integrate exp(arcsin(x)), it is possible to do by hand without a lot of effort.

After successfully installing maple 11 on my computer running Ubuntu I start maple by executing the xmaple command. That will give the splash screen and later start a window which is just grey with no menu bars. In the end the startup tip dialog appears and when I select anything from there it disappears and nothing happens after that. The window stays gray. If I press the location of the window where the menu bar should be (also press F10) I get the menu items. Selecting any of them, like options, will invoke a dialog which is fine but there is nothing happening when opening a file or wanting to run an example or such.

I think that I will start moving to file all of my bug/error/oversight complaints in blog entries. This way (in theory), they are more easily indexed on this site. So, I was playing around with a procedure today: [>restart; testproc:= proc(Q::`=`) local a; ##IF STATEMENT## return a; end proc: [> The if statement noted in the procedure always took on the following appearance: if #Check if lhs(Q)=a# then #assign rhs(Q) to a#;fi; Writing my procedure as above ensured that the restart would be executed every time I changed my if statement. My first if statement went like this:

The Vim editor ships with a maple.vim file, which is a "maple mode". It was first created by Charles Campbell, and I provided some updates (up to Maple 9.5). I am about to rev that up to Maple 11, so I would like to know if there are any feature requests which I should consider rolling-in at the same time? If you have little bits of vim scripts which you yourself use, by all means, send them along! [You'll get full credit for that, I am fine with being just an aggregator...

I mentioned in another blog entry that I was considering doing something with slide rules. I mentioned in yet another entry how I hope to pass on some of newly acquired mathematical knowledge to my grandkids. I'm working on a slide-rule for kids project. Although I didn't use maple in any phase of this project, it was definitely a stepping stone on the path that lead up to it. Below is a picture of one of the prototypes - a very rough prototype. read more about it by clicking the "read more" link below ---

Hi, recently I posted a question regarding the problem that by calling same procedure with same parameters I was getting different results. http://www.mapleprimes.com/forum/function-in-maple-returns-me-different-results#comment-10172 I was playing little bit more with this problem and I found another problem / bug. If I define generalized Gaussian probability density function and set parameters such that it is Gaussian probability density function (definition involves absolute value), my procedure returns number in order 10^131. If I call the same procedure with normally defined Gaussian probability function (definition does not have absolute value), the function return 0.7, which correct results.

I thought this might be of interest to anyone interested in seeing some simple ciphers broken with maple. Download 6039_huffaf_crack.mws

Do not understand the answer to this.. eq1:=X=(1/Rp/(1/Rp/Rp+w*w*Cp*Cp)); eq2:=Y=(w*Cp/(1/Rp/Rp+w*w*Cp*Cp)+1/w/A/Cp); expand(solve({eq1,eq2},{Rp,Cp})); {Cp = RootOf(A+1+(-Y*A-2*Y)*_Z+(X^2+Y^2)*_Z^2,label = _L2)/A/w, Rp = -X*A/(Y*RootOf(A+1+(-Y*A-2*Y)*_Z+(X^2+Y^2)*_Z^2,label = _L2)-A-1)} What are the: _Z _Z^2 ? and what is the label = _L2 ? Can I make the answer look like somthing more understandable?

We are pleased to announce the first winners of the monthly Maple Mentors Awards. Jacques Carette and Robert Israel will receive a prize of their choice to thank them for their involvement with the MaplePrimes community. Jacques has consistently been a valuable member of MaplePrimes, posting clear and insightful information on advanced topics. Robert in particular has been active in the Student Forums on MaplePrimes since their inception and we would like to recognize this. One member had these comments on the two:

Hi, I am not proficient in Maple, I start to use it one week ago, but it already help me to solve problem that is unimaginable to solve for me by hand. Unfortunately, I encounter a problem which I am unable to solve by myself. I have written a simple function calculating Taylor expansion of two functions and then calculate some statistics of coefficients. Strangely, if I call the function twice consecutively, it always returns me different results. I tried to save intermediate results, but it is even more weird. The input is the same, but then in the middle of iterations results starts to differ. I am desperate.

Hi, I ran into this in my Modern Algebra class; and decided it might be of interest. We were given the problem to: "Find the least prime p s.t. 2^(p-1) congruent to 1 (mod p^2)" EVERY prime p > 2 has the property, 2^(p-1) congruent to 1 (mod p), by Fermat's Theorem (since 2 does not divide such prime p). But, mod p^2 is another story. This was given in a class where everything is done by hand calculation, based on theorems. I couldn't come up with any way to determine it other than brute force. Here is a tiny Maple snippet which finds it:

First, the shortcoming: Open a new Maple worksheet (I always work in Worksheet mode, so I haven't tested what happens in Document mode), and type anything in 2D Math Input into a line but do not execute that line. Save the file, then open it in a text editor or word processor. If you scroll down to the line containing the information for what you just typed in, you will notice that the attribute "input-equation" will be null; that is, it should say input-equation="" Even though there is input on the line, Maple doesn't add anything to the "input-equation" attribute until the commands are executed.

Some of the most significant members of Maplesoft’s math team are interviewed in this episode: Dr. Juergen Gerhard, Dr. Edgardo Cheb-Terrab and Dr. Allan Wittkopf, who give an inside look at just what is involved in designing and building sophisticated algorithms for advanced mathematics. They discuss symbolic computation, the new Physics package in Maple 11, Maple's DE and DAE solvers, future developments, and ballroom dancing.
