Having trouble with a double summation function that calls itself recursively.

S2 := (p, k, n)-> piecewise(0 <= n and n < k, 1, n < 0, 0, sum(sum(p^y*(1-p)^(m-y)*S2(p, k, n-m), m = y+1 .. y+k-1), y = 1 .. n-k+1));

When evaluated with S2(p,2,-1) and S2(p,2,1) it works correctly (first two conditions are working)

However, when I try evaluate S2(p,2,2) Maple appears to run unbounded(?) and chokes. In fact, doing...

Aaaargh!  I'm going crazy here.  If anyone can help I will be massively grateful!

My problem is quite simple:  I have a long list of data, in the form: f1:=[some matrix] f2:=[another matrix]...etc.

The data has been read in from a different program.  I am trying to write a program to go through each matrix one by one and perform some operations on it.  Usually to do this I take some dummy variable, say i or j, and write:

Dear All,

I would like to use fsolve in an algorithm, and have problems with handling the cases where there is no solution. The help writes that in case of no solution, the fsolve assigns a NULL value to the output variable. So I exoect that I should be able to handle cases where I have solutions using the "if solution<>NULL ..." statement .

In some cases it is not true: fsolve writes out the input, instead of saying that there is no...

Hello,

I tried to compile the Java program located in $MAPLE/samples/OpenMaple/Java/simple under Linux.

While compiling worked, running the .class file results in a crash of th jvm:

i need to solve a system of ecuations with a generic function e.g V(q). i know that dif(V(q),q) is possitive and second derivative is negative. how can i incorporate this information?

q is my desition variable

 I have been trying to do algebra in maple but I do not know how to write in it The problems I am having is with the word problems Can I just write it in ?

1.what is the form using to find the limit in the mapple? .

f(1). Find the limit of sqrt t*f(t) when t approach o+

2. what is the form using to graph the implicit function Ax^2 + bxY + cY^2=D

with A= 1 , b=1,c=1, D=2010

Base on the above examples. What is family of the curve is ax^2 + bxy + cy^2 = d

I wonder to evaluate divergence theorem when f:xi+yj+zk and the surface is a sphere with equation x^2+y^2+z^2=9 when there is a hole in the sphere with equation x^2+(y-1.5)^2+z^2=1

the volume that we consider is space between inner sphere and outer sphere

thanks 

Question 1:

Animate the plot of the graph x^2 + Bxy + 4y^2 = 2010 letting the parameter B range from -10 to 10 using frames 100. Determine when family of curves is 2 straight line.

Question 2: 

Animate the plot of the graph z^2 + c = x^2 + y^2 letting the parameter C range from -10 to 10 using frames. How can I graph and Describe what is happening

I saw this error during computing

Error, (in assuming) when calling '`simplify/sqrt`'. Received: 'Maple was unable to allocate enough memory to complete this computation

Is there any way to overcome the error?

thanks

I'm new to maple and am evaluating it as a means of deriving symbolic equations of motion for a system comprising two flexible bodies sliding relative to one another and rotating in 3d space using the Boltzmann Hamel equations.  I have written up the approach but the maths is extremely tedious by hand so I wondered if maple could help.  For  a start how do I define a simple indexed 3 element vector and then create the skew matrix equivalent (tilde matrix) as...
