In the following examples I attempt to remove integer multiples of Pi from sin/cos. Nothing works.

Why? How do I make it work?

Thank you.

term1:=cos(Pi*(3*a-2*n));
> term2:=cos(3*Pi*a+2*Pi*n);
> term3:=cos(3*Pi*a-2*Pi*n);

                     term1 := cos(Pi (3 a - 2 n))

 Work plan for the Russian Maple Application Center in 2011.

 1. Popularization of the new features of Maple 15.
 2. Popularization of educational MAC-articles.

 3. The transformation of the most popular Russian-language Internet maths textbook to the business card of Maple.
 4. Further approval of Maple as the best assistant in preparation for the delivery of the Single State Exam (Russia).
 5. Further approval of Maple...

In the new Maple 15, if any calculation or process requires more than a few seconds, the cursor does not change to the hourglass (or equivalent) symbol. This makes it difficult to tell whether anything is happening and gives the impression that the program has hung.

I suggest that the hourglass (or equivalent) be resurrected whenever anything takes more than a few seconds.

any of the numerical factors that multiply the successive terms in the expansion of an expression of the form  (x + a)^n,  for integral n,  in accordance with the binomial  theorem. These are any terms of the form
               ∑x^(n-k)*a^k*binomial(n,k)

how to get it.

convert((x+a)^n,Sum,x)

but ,i get a anwer that i don't want

Dear all!

I wrote a program but when I run it I get an error as: " can not evaluate the solution further right of ..., maxfun limit exceeded ". I tried some ways to work around it, for example I tried "maxfun=500000" and more. Also I tried "maxfun=0", but they don't work. How can I solve my problem?

O.K. Isolved this problem myself. We can solve such a problem in two different ways. 1.by adding the expression "method=mebdfi" and 2. by adding expression "'stiff=true'".

1 -√3 - x² -√2- x²  = 0

From this expression I want to extract only terms with the variable x.

F := (1/2/Pi+Q*cos(k*x))^2*(1/2/Pi+Q*cos(k*y))/(1+beta^2*(1/2/Pi+Q*cos(k*x))^2);

I don't want to manually write it out rather extract the terms programmaticallly. I want to be left with

(1/2/Pi+Q*cos(k*x))^2 / (1+beta^2*(1/2/Pi+Q*cos(k*x))^2)

I have tried the collect fucntion but that did not seem to do it. Any suggestions...

The (new, Maple 15) Programming Guide is available for download from the Documentation Center.

Like in the version 7 where that variable didn't exist.

I'm using the following function for my project,:

printlevel:=2:for Prc from 2 by 1 to 100 do for B from 2 by 0.5 to 100 do (mf(Prc,B)):=(f(Prc))*(m(Prc,B)) end do end do

Is there any way to be able to sort the answers in ascending order? I tried to use sort, but when I put sort(mf(Prc,B)) it gives me a wrong answer and jumps into Prc=101 and B=20.5.

Also is there any way to put a condition for show only real numbers, without complex numbers?

Pleaes visit the attached file and tell me what should I do. Thanks a lot.

Hi there,

I'm doing a lot of computations with Maple right now (currently the ancient 10 and 12 versions but maybe soon 14).

I would like to do Unit-Tests of my Software as known for instance in JUnit with Java. Is it possible or do I have to use the ASSERT(...) - statements?

Thanks in advance.

let x , y in R , say for example

x=0.1243134710481

y=0.1243234710571

Then we can compare the digits where x and y agree and where they differ.

In the example , x and y agree on the first 4 digits , differ on the next digit, agree of the next 5 digits , differ on the next two digits, and agree on the last digit.

Dear all

I've written a program, but it shows an error related to maxfun limit when I run it. Can anyone tell me what the problem is? and how can I solve it? The program and the data file are attached.

Thanks a lot.

Hello all,

This is my first time posting here; I usually find answers to all my questions by searching patiently but I was unsuccessful with this particular issue.

I attend an introduction Maple class and i'm building an animated bike as project. I was already rather comfortable with Maple so i'm trying to show off a little by adding lots of cheesy details to the scene, even if unnecessary. However, some objects such as the sky, which i would like to...
