The polar form of complex number is
- i
i
2 i
4 i
The inequality |Z - 4| < |Z - 2| represents the region given by
Re (Z) > 0
Re (Z) < 0
Re (Z) > 2
None of these
If | z | = 1 and (where z ≠ -1 ), then the value of Re(ω) is
0
Given that the equation z2 + (p + iq)z + r + is = 0, where p, q, r, s are real and non-zero root, then
pqr = r2 + p2s
prs = q2 + r2p
qrs = p2 + s2q
pqs = s2 + q2r
