Question

if f(z) ={ 8 - (1/8)} then what will be the value of f(z) + f(1/z)

Answer 1

f(1/z)=8/63
f(z)=63/8
=f(z)+f(1/z)
=63/8+8/63
=3033/504

Answer 2

Answer:

0

Step-by-step explanation:

f(z)={ 8 - (1/8)}

∫f(z) = 8z - z/8 ;  ignore C

put z = 1/z

∫ f(1/z) = 8/z -1/8z

derivate

f(1/z) = -8 + 1/8

So f(z)+f(1/z) = {8-(1/8)} + {-8+(1/8)}  = 0
