Hello everybody!
 

I have a problem that's cracking my skull for the past few days and i can't seem to find an answer.
I have three equations with three variables, wich i have to solve.

> f1 := (x, y, l) -> x*z-l*x+2*z*l;

> f2 := (x, y, l) -> x^2+4*l*x;

> f3 := (x, y, l) -> -x^2+4*x*z-12;

I want to generate values which have a N(0,1) distribution (and also some which have a N(0,1/2)+I*N(0,1/2))

I have found the RandomVariable(Normal(0,1)) command but this just tells me things like _R44 and I need the numerical value.

Please can you help? (with both distribution cases)

How do I change the size of a plot? For instance, how do I make a plot fill an entire page?

I am trying to replicate the Parrondo paradox which can be found for example here books.google.co.uk/books  and

Why does the binary entropy function have the form   H := -p*log(p)-(1-p)*log(1-p);
Why does not the maximum occur when H=1 and p=0.5 ?

H := -p*log(p)-(1-p)*log(1-p);
plot(H, p = 0 .. 1);

> x := [1, 5, 3, 7];
                                  [1, 5, 3, 7]
> y := sort(x);
                                  [1, 3, 5, 7]
 

I have written a procedure in which I create a matrix and then manipulate (change) the matrix until certain conditions are met (a while loop).  I would like to know when an iteration of my loop does not make any changes to my matrix (but the stopping conditions are not yet met) so that I do not enter into an infinite loop.

I have only found rand() which gives me integer values and I need to generate (a lot of)  random rational numbers.

The boundary (0,2) doesn't really matter but I do need the numbers to at least go up to 2. Else any rational will do.

Thankyou.

Here is what I would like to do:

for i from 1 to m

  A[i] = plot(...)

end do

Now, how do I plot this array A of plots?

Thank you,

ck

Hi,

I want to find the limit of the expression (see maple sheet) using l'hopital's rule as sigma approches to zero.

Please help me out.

Thanks

Maple produces a very long answer which I can see on the monitor, but on the printer it is truncated.

Is there a way somehow wrapping the too long lines?

Thanks

Hello,

How can I know which component is embedded in another one when I calculate PrimeDecomposition.

In this file which is attached I know <y> is embedded in <x,y> but how can I ask this from maple?

Which Maple command can helps me to know one component by PrimeDecomposition is embedded in another one.

File is attached here.

Bye,
