Hi Will,

i didn't know if i had to answer or not... anyway..

maybe i didn't explain very well....

B^2 should not be = J^2*1.27^2 ?

so if J^2 = -1

from 0.19 + J0.27

A^2+B^2 = 0.19^2 + J^2*1.27^2 we have 0.19^2 - 1.27^2 not 0.19^2 + 1.27^2

i just wanted to understand the step that i didn't get....

Hi Vito

Sorry for the delayed response - I got off on another tangent.

When you use the equation sqrt(a^2 + b^2) you don't square the j term. You only square the coefficient, b. So, j does not get squared, just b.

However, when multiplying out the polynomials for reduction, you very often will run into a j^2 term, which will evaluate to -1.
