1. if f
p(a) =
p 
k=1 ( cos ka/p
2 + i sin ka/p
2 ). then what is
n
f
n(
) ?
2. if | z- i Re(z) | = | z- Im (z) |,then z lies on:
a. Re(z)=2
B. Im(z)=2
c. Re(z) + Im(z) = 2
D. none of these
3.if a is a complex constant such that az2 + z + conjugate(a) = 0 has real root then
a. a+conjugate(a) = 1
b. a+conjugate(a) = 0
c. a+conjugate(a) = -1
d.the absolute value of real roots is 1
4.what is the reflection of comlex no. 2-i / 3+ i in the straight line z(1+i) = conjugate(z) ( i - 1) ?
