Unformatted text preview: f ( z ) = 1 ( z1)( z2) (10 pts.) Obtain the Laurent expansion centered at z = 0 for each one of the following three regions: (a)  z  < 1, (5 pts.) (b) 1 <  z  < 2, (5 pts.) (c)  z  > 2 (5 pts.) [Hint: Reexpress f using partial fractions.] 5. (25 pts.) Locate and classify all the singularities in the nite plane of f ( z ) = 1 z (exp ( z )1) . (8 pts.) Calculate the residues at these singularities (8 pts.). Give the rst two terms of the Laurent expansion about z = 0 (8 pts.). Is the point at an isolated singularity? (1 pt.) Due at 5pm on Wed. October 28....
