## applying function using multiple lists as variable...

Using the formula: ((A/B)^(3/2)*(C*D*E/F*G*H)/(I/J)^(3/2)*(K*L*M/N*O*P) I have a different list of [a1,a2....a11] for each variable except A,B,I,J which are constants. I've seen examples for using a single list, but never for using multiple lists. There are 11 numbers in each list, so I should get 11 answers. Thanks for the help. Will

## MathContainer...

I am trying to read from a embedded MathContainer a simple expression. I am using the expression func:=parse(GetProperty('MathContainer0', value)); When I execute the above code I get the error, "incorrect syntax in parse: missing operator or ';' (12)". I have read over the help pages on MathContainer, GetProperty, and parse to no help. The syntax looks fine to me. The parse help page did indicate that MathML may be reponsible, but the MathML help page was no help. What is the syntax error that is occuring? The expression works fine if I use func:=parse(GetProperty('TextArea0', value));

## Basic Do Loop Error...

Hi Guys I just started learning Maple and I have basic question which is annoying me. I use Maple 10 and when I execute the following statement I get the final result as the output instead of a set of numbers. for i from 6 by 2 to 15 do print(i) end do; 14 what am I doing wrong? Am I missing something here? I tried searching all over but could not find a solution. Help is very much appreciated. Thx in advance

## Matrix display in equations...

I have a situation which is not really complicated but it would be awkward to explain it in a text post, so I have described it in the attached worksheet. It has to do with the display of matrices. If anyone has the time to take a look at the worksheet and propose a solution I would be grateful. -Thanks View 2292_Matrix Display.mw on MapleNet or Download 2292_Matrix Display.mw

## automatically input times steps into output=array ...

I am using the output=array([]) option in dsolve which works fine if I write in each time step of interest eg output=array([0.1,0.2,0.3]). No problem for 3 values. However, I wish to input a large number of values. Can this be automated for regular time steps?

## maximize function, Weierstrass M-test...

I would like to write a procedure which uses the Weierstrass M-test on uniform convergence. I wanted to use the maximize function (to recognize if the function is bounded and to get upper bound) but this function doesn't work in many simple cases. ``` assume(x::float); assume(n::integer); maximize(2*sin(x)+cos(x)); ```
`          maximize(2 sin(x~) + cos(x~))`
``` maximize((-1)^n); -infinity ``` Actually, I don need maximize function but just to get any upper bound. Is there a way?

## how can i calculate the parameter of the matrix wh...

here is the matrix,for example, result:=Matrix(2, 2, {(1, 1) = 4*c-4, (1, 2) = -2*c+3, (2, 1) = -2*c+3, (2, 2) = 4*c-15/4}) for what region of c, this matrix is positive definite? I typed the following in Maple, > IsDefinite(result); / 2 \ 0 <>

## Equal Matrices...

Suppose I have 2 Matrices, say each is 3 by 3. Is there any way I can check for the equality of all corresponding elements of the matrices without resorting to a for loop or something like that?

## How to solve this differential eq.?...

Hello, I need some help on how to solve this eq: A(z)*diff(P(z),z,z)-alpha(z)*P(z)-beta(z)*P(z)^3-gamma(z)*P(z)^6=0; A(z), alpha(z), beta(z), and gamma(z) is known. P(z) is the unknown. When I tried to do this by solve command, I get "warning, solutions may have been lost". I really need help on this from the experts out there... Thanks, G.

## similarity transformations...

In diagaonalizing a Hermitian matrix, the eigenvectors come out un-normalized, and as a result, when performing a similarity transformation on the original (Hamiltonian) matrix, the diagonal elements come out proportional to the true values, not the values themselves. I can't find out how to simply normalize the eigenvectors so that they can be made into the appropriate matrix (and its transpose complex-conjugate). There's got to be a simple way, but I can't seem to find it. Can someone point the way? Thanks Carl David
