Dear All,

Please can someone help me in writing the Maple program for the following, I am stuck :

theta(n):=((beta*a)/(Pi))*(A1(n)+A2(n)

with

A1(n)=(sin((n+1)*beta/2))/((n+1)*beta/2)

A2(n)=1 for n=1

A1(n)=(sin((n+1)*beta/2))/((n+1)*beta/2)

A2(n) = (sin((n-1)*beta/2))/((n-1)*(beta/2))           for n is not equal to 1

note pls: n= 1, 3, 5,....

Thanks in advance

I have a question:

let t(n)=sum( (binomial(n,j))^4, j=0..n )  , t(-1)=0, t(0)=1

and (n+1)^3 *t(n+1)=(2n+1)*(a*n^2+a*n+b)*t(n)+n*(c*n^2+d)*t(n-1)             (1)

I want to Print(a,b,c,d) so that t(n) satisfies the recurrence relation (1)  where a,b,c,d are integers and their ranges are from

-30 to 30.

Please help!

Could you tell me how to write the following surface integral in Maple, please?

Hello all,

I am new to maple and have to input the following attached equation into maple to be solved;

How do I do this?

Thank you in advanced for your help!

Cheers,

Keith.

(This question applies to the Win32 version of Maple 15.)

I've got a python wrapper for the OpenMaple interface, and I've managed to get most of the callback functions in the MCallBackVector structure passed in to StartMaple to work, but I've never (ever) seen the queryInterrupt callback called.

To investigate this, I modified the 'omexample.c' example (found in the <Maple install Dir>\samples\OpenMaple\cmaple directory installed with the product...

I have a beam rigidly secured at one end (a diving board) and want to find the deflection of the beam when a mass is applied at the end. 

I have the differential equation

eq := diff(v(x), x, x) = P*x/(E*Iz) # E youngs modulus and Iz the moment properties of the diving board. 

The solution says to integrate to get deflected slope of the board.

int(rhs(eq))

How do I do to get a single number (decimal) when I evaluate an input.

For example, I write this:

evalf((546, 1/1000000000)*(7, 0)*sqrt(36+1/(7, 0)^2));

but I still get the same thing as I inputed as a response, how do I do to get an actual number?

Hi,

when i tried to solve the following equation, i received ""Warning, solutions may have been lost"":

a := [1,1,1,2,2,3];

number of appearance of 1 is 3

number of appearance of 2 is 2

number of appearance of 3 is 1

any short code can count this

I have a question about the different possibilities for calling a little used function from a package. It seems that there are three ways to do that:

1) Load the package and use te short form of the call e.g.
> with(combinat);
>randperm(5);

2) just load the command e.g.

>with(combinat,randperm);
>randperm(5);

3) use the long form of the call e.g.

>combinat[randperm](5)

4) with the use command e.g.

Hello,

I have a .dat file with three colluns, namely E,  a and b and N rows. The objective is to compute a function of a, b and a given value K F(a,b,K).  I would like to write a maple code that read the element in the first colum, E. If  E is lower or equal to a given value K, than we compute a term of f(a,b,K). After check the N rows, F(a,b,K) = sum(f(a,b,K)). I am new to maple, so I can`t figure out how to write this function.

Hi

I have a plot using plot() function. I would like to label the x-axis using math symbol (example a_subscript 0).

Is there any way I could do this. I tried label=["a[0]", "some text"]. However, the label on x-axis appears as a[0].

I am using Maple 15 Worksheet.

Thanks in advance.

I have these two procedures which produce 2/3 parts of my snowflake. But HOW do I angle them to put them together? Or should I modify one to cover the entire snowflake? If so, how should I modify my procedure?

This produces an "up right" fractal of a shape basically like this:   __/\__

Koch:=proc(n::posint)    
  if (n=1) then return("F"); fi;
 ## now n>1
  return( cat( " ",Koch(n-1), "L", Koch(n-1...

Hi,

I'm having trouble finding the maximu of the following function over a defined range. (Note: I dont have the global optimization toolbox... don't have that sort of money!)

From my system of 3 DE's I get the solution with dsolve.

One such solution:

f(G)=_C3 MathieuC(b,p,G)+_C4 MathieuS(b,p,G)

For given b and p. How can I find the maximum for a range of G. For example G=0 .. 100.
