Hi all,

## Correcting the initial guess in a loop...

Maple

Hi all,

I attached a program here and the desire is the calculation of Nu.As you could see through the attached file, the F2(r) function contains an 'integral' which makes it difficult if I want to calculate F2(r=1) and it goes the same for D(F2)(r=\phi). So I firstly corrected the F2(r) function as FF2(r) in which the parameter R is calculated in the top of the file. Afte I replace the values of \phi and 1 in the FF2(r) not in F2(r) just because of the integral. The Nu is calculated finally, but it differs from the initial guess. How could I make a loop in order to correct the initial guess by replacing the first Nu calculated in the end of the program??

Ther is a problem and that is the "k" which must be entered in this part in each loop:

Digits:= 10:

K:=Nu->( k )

I do not know whether or not it is possible to change it so that the program identify the 'k' and replace it in the "K:=Nu->( k )" for k.

## Solve Integral numerically or analytical...

Maple

Hi all,

How can I solve this Integral?

I do want to learn how could I solve numerically the attached integral. As you can see through the file, there is written one method, however, it is not able to solve the integral.

## Solve a system of 3 equations...

Maple

Hi all,

Is there anyone who could solve this equaiton? I think there is no solution!!!!

## How solve this PDE...

Maple

Hello everybody,

I want to solve this pde.the desire solution is V(r,z). three boundar conditions are written that two of them are related to rhe radial and one is related to the longitudinal coordinate.

I attached the solution for you. but this solution is derived by Matlab. Now, I just want to resolve it by Maple, but I couldn't reach it. Please let me know the correct way asap.

Thanks a lot.PDE.mw
