  Hello Bob & PSN;

Im not so sure this stuff is correct because
its my understanding that Q and Damping
are simply inverses of each other just like
Period and Frequency. I was unable to
get the inverse result simply by
alternately clicking the buttons
using the same input values.

Like Q = 1 then damping = 1
Like Q = 0.5 then Damping = 2
Like Q = 2 then damping = 0.5
???
Also, Whats the proper symbol for damping ?

My level of math is only high school
to first year college.

My brain has most probably been damaged
by all those nut house drugs the Government
has forced down my throat with coercion
and duress.

Im just hoping to easily get an answer that makes sense to me here.
