Derive equation 1 from Lecture Notes p.27-1
We have
and
and
Similarly
and
using above equations into first equation we obtain
but
So finally we obtain
Ref: Lecture Notes p.29-3
Obtain expressions for using eq (6) Lecture Notes p.29-2
Using eq (6) from Lecture Notes p.29-3 , we obtain
so
where
where from previous result
Using eq (6) from Lecture Notes p.29-3 , we obtain
By using eq 6 from Lecture Notes p.29-3 , we obtain
