Question Number 21005 by Tinkutara last updated on 10/Sep/17
If z_1  = a + ib and z_2  = c + id are complex  numbers such that ∣z_1 ∣ = ∣z_2 ∣ = 1 and  Re(z_1 z_2 ^� ) = 0, then the pair of complex  numbers ω_1  = a + ic and ω_2  = b + id  satisfy  (1) ∣ω_1 ∣ = 1  (2) ∣ω_2 ∣ = 1  (3) Re(ω_1 ω_2 ^� ) = 0  (4) ∣ω_1 ∣ = 2∣ω_2 ∣
