hi,

I'm currently proctoring for my univeristy math dept.  They ask me to put policy on testing website.  Please help me how to do that? thanks,

Hi there, I'm trying to express the following expression

sin(c + I * (sin (d + k * sin(t)))

in terms of Bessel functions. I've been knocking my head against it trying to do it by hand for a while now and someone suggested maple could help.

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
