AOA... I have facing a problem to edit a figure in MS worl after coping from MAPLE file. Because we my paper is accepted and will publised after minor revesion which given below:

PhD (Scholar)
Department of Mathematics

I really need help!
please help to solve the boundary value problem by method of shooting.
I never met with this problem and I can not quite figure out how to solve this problem in maple
Thanks for the help!

Hello

I have a nasty expression which I want to simplify in terms of another expression/function I have defined. 

Please can you tell me how to do this?

A simple example would be:

myFunction := a^2 + b^2

horribleFunction:= a^2 + b^2 + ...

I want it to simplify so I get something like

A(myFunction)^n  + .....

Above is just a simplifcation to try and explain what I mean

Thanks

We have two texts in a certain language, represented as Maple  strings,  e. g.
"die einkommen der landwirte sind fuer die abgeordneten ein
buch mit sieben siegeln um dem abzuhelfen muessen dringend alle
subventionsgesetze verbessert werden" and
"die steuern auf vermoegen und einkommen sollten nach meinung
der abgeordneten nachdruecklich erhoben werden dazu muessen die
kontrollbefugnisse der finanzbehoerden dringend verbessert werden".
We have to find the maximal common subsequence of the words in the both texts,
i.e. "die  einkommen der abgeordneten muessen dringend verbessert werden" for
the above. If there are a few such ones, then only one is enough. How to program
that by SringTools and/or EssayTools in maximum efficient way? A compiled procedure is welcome.

We have just released an all-new, second edition of the Calculus Study Guide.

This guide has been completely rewritten and greatly expanded and to take full advantage of Maple’s Clickable Math approach.  It covers all of Calculus I and Calculus II and has over 450 worked examples, the vast majority of which are solved using interactive, Clickable Math techniques. 

Not only is this guide useful for students learning calculus, but it can also serve as a guide for instructors interested in pursuing a syntax-free approach to using Maple in their teaching.

See Clickable Calculus Study Guide for more information.  For even more information, you could also attend a live webinar about the new study guide next Wednesday.

I was running some wav files through the spectrogram increasing the fft window size.  Generally just playing around.

I have run into an issue.  After running a few times the mem usage for maple.exe starts to run high.  I get it up to 600,000 K and still seems to run okay - ie able to produce a spectrogram.  However running it again at a higher window size of course eats up more memory and right around 1,000,000 K mem usage everything slows down and it appears to freeze.  The spectrogram is not displayed, after a short while CPU usage drops to zero the heartbeat circle (evaluating symbol - bottom left corner) stays solid and everything appears to stop. 

It is possible to close the worksheet in the same maple session after some time and open a new one.

Another note.  After one worksheet has ramped up the mem usage to a large value say 800,000 K (it doesn't really matter) .. when I close the worksheet (in the same maple session) the mem usage remains high even after a restart;gc():   I not sure if this has been normal throughout the ages, but I thought after closing a high mem usage worksheet in the same maple session the mem usage in the windows task manager would have updated back down under 100,000 K at least. 

The system Maple is running on right now is a P4 3Ghz Windows XP at 2.50 GB RAM Maple 18.00 stnd GUI 32 bit.  Using the spectrograms example in the application center for start.

Any insight as to why the computer starts to freeze up around 1,000,000 K mem usage would be helpful.  Also why closing a worksheet had no effect on the mem usage.  Would be interesting to know if this occurs on other machines as well.

As I stated in an earlier post, I'm new at this.

I'm trying to write a procedure to calculate what is called a "crescent latitude". The full formula can be seen here: https://db.tt/QAUzH5i0.

b is equal to 0.081819221; it takes a single parameter φ (latitude of a location in degrees)

I normally get errors like unable to parse, unable to match delimters, etc. and the result is the name of the procedure and whatevere value of the parameter I put in parenthesis, not the calculated value.

Anybody can help?

Thanlk you

Hello guys

I have a problem in runge kutta method for coupled differential equations .For example consider these equations:

a*Φ''''(x)+b*Φ''(x)+c*Φ(x)+d*Ψ''(x)+e*Ψ(x):=0

d*Φ''(x)+e*Φ(x)+j*Ψ''(x)+h*Ψ(x):=0

The boundry conditions are:

Φ(0.83)=1;Φ'(0.83)=0;Φ(-0.83)=1;Φ'(-0.83)=0;Ψ(0.83)=1;Ψ(-0.83)=1

Φ(x) and Ψ(x) are unknown functions and a,b,c,d,e,j,h are constants . I want to get answers by runge kutta numerical method .

i used this form of algorithm but i cant do it :

please help me to solve these types of equations.

Hello guys,

I think that the title explains the question very well. Is there any function in MAPLE that allows me to generate N random numbers considering a mean value, standard deviation and a percentile?

Thank you,

hi

I need to export or save my plots during the run out of maple as jpeg or gif but I can not find any command to do it. the only way i found is right click on the plot and then export it but i need program do it by itself during the run.

thanks

I'm trying to use Rodrigues' Rotation Formula to graph a circle--by rotating a point, naturally--and I'm not sure how to implement that in Maple. For something like a function, allowing a variable--say, x--to vary and produce a curve is natural, but the evalm() function doesn't handle that very well: I can use the formula to *evaluate* the rotations, but not to use them to graph the circle.

I looked for something like solids of revolution--after all, I'm doing something pretty similar--but didn't find anything helpful; apparently there's a way to make solids of revolution, but it's pretty specific and would be difficult to adapt?

Hello Those who are in Mapleprimes.

I want to know the meaning of [].

That is,

a:=[1,2,3];

b:=a[];

What were returned was 

b:=1,2,3

This result is the same as that obtained from

b:=op(a);

What kind of meaning does a[] have?

I want to know the logic of this expression.

Can I ask you about this?

Thank you in advance.

AOA... Dear when i expand

sum(sum(binomial(n-1, i)*x^(n-i-alpha)*(-a*n)^i*c[n]*GAMMA(n-i+1)/GAMMA(n-i-alpha+1), i = 0 .. n-1), n = ceil(alpha) .. M)

for M=2 and alpha=1/2 its answer is 

-sqrt(x)*c[1]*sqrt(-(1-x)/x)*(2*x-1)/(sqrt(Pi)*(1-x))-(1/4)*c[1]*hypergeom([3/2, 2], [3], 1/x)/(x*sqrt(x*Pi))-(4/3)*x^(3/2)*c[2]*(-(2-x)/x)^(3/2)*(2*x-1)/(sqrt(Pi)*(2-x))+(2/3)*c[2]*hypergeom([3/2, 2], [4], 2/x)/(x*sqrt(x*Pi))

which is very difficulty i want its answer in Gamma form i.e.

2*sqrt(x)*c[1]/sqrt(Pi)+(8/3)*x^(3/2)*c[2]/sqrt(Pi)-4*sqrt(x)*c[2]/sqrt(Pi)

Pl help me

Is there a book or a place where to start learning programming in Maple from the very beginnings?

I have some experience with RealBasic (now Xojo) and C, so I am not a complete newbe but I am at loss with Maple and I have hard times following the help system to learn.

Thank you

Martina
