If f z z2−3√2z−1 then find f 3√2

Web27 feb. 2024 · The poles are at z = ± i. We compute the residues at each pole: At z = i: f(z) = 1 2 ⋅ 1 z − i + something analytic at i. Therefore the pole is simple and Res(f, i) = 1 / 2. At z = − i: f(z) = 1 2 ⋅ 1 z + i + something analytic at − i. Therefore the pole is simple and Res(f, − i) = 1 / 2. Example 9.4.4 Mild warning! Web30 dec. 2014 · Residue of z 3 ( z − 1) ( z − 2) ( z − 3) at z = ∞. Well, the total sum of residues is zero. But the given answer says 6. We calculate residues with R e s f ( a) = 1 ( n − 1)!
