(a)If complex function f(z) has a simple pole at z=a on the real axis
please show the following theorem : lim ∫f(z)dz = πi Resf(a)
r→0 C2
,where Resf(a) is the residue of f(z) at z=a , the path C2 is
C2: z=a+re^(iθ) , 0≦ θ≦π
(b)Integrate the following complex function counterclockwise around C.
cosz
── , n=1,2,......, C: |z|=1
z^n
拜託各位大大了 這一題是98成大工數 謝謝!!
