hy everybody..i need some help here to finish up my project about Helmholtz`s equation..

1. What are the Avantages/disadvantages of the Helmholtz`s equation?
2. Where can i find the example or the easy way to understand about this equation?
3. Algorithm for this equation?

:confused:

Interesting topic. You made a project. What have you worked out so far ? What are your ideas about the answers to the 3 questions ?
 
i`ve found dat dis equation basically is related to elliptic partial differential equation..and i hv only found the general advantage of this method.
 
anyone can help me please..
 

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
