(changes in arg h (z) as z traverses lambda)/(2pi) =(adsbygoogle = window.adsbygoogle || []).push({});

# of zeroes of h inside lambda +

# of holes of h inside lambda

now the doubt i have is what happens when the change i get in h (z) is say 9 pi/2 .... because then i would have a 2.5 on left side of the eqn ... so do i round it up and and say the function will have 2 zeros? (assuming it has no holes)
