I have now got the formular

I am trying to use maple to put it in the form wsq(A)+B.

How can this be done. I can not get the factor comand to work. Thanks

Ok well that was a waste of time i do not actually need to expand C(k), F1, F2 and F3 because these are just numbers. In the solver i am trying to program i can just enter these valuese as F1real + i* F1img.

Still is there a way to expand determinates of matrix in maple?

Thanks

Thanks for cleaning my thread up and thanks for the help.

Now say if i have a matrix [ A(w, k) B(w, k); C(w, k) D(w,k)] were A B C and D are dead long complex (as in have i in) expresions. Is there a way in maple to say get the determinate then rearrange the determinate into the form X(w,k)+iZ(w,k)

Then Rearrange Z in terms of w and rearrange X in terms of k?

... So far im have been doing it by hand ... just writing down X takes up a page...

Also H(k) is hankle funtion which = J1(k)+i*Y1(k)

were J1 is first order bessel function and Y1 is second order bessel function.

I know nothing about bessel functions but as they are in the terms A, B C and D i need to be able to rearrange that equiationand stated above into terms of k.

Is this even possible?

Thanks for the help
