Math Problem Statement
Which of the following options is/are true?
If ∣ z − 3 z − 1 ∣
3
z−1 z−3
=3, then Re ( z )
12 7 ∣ z ∣ 2 (z)= 7 12 ∣z∣ 2
If ∣ z − 2 z − 1 ∣
2
z−1 z−2
=2, then Re ( z )
7 12 ∣ z ∣ 2 (z)= 12 7 ∣z∣ 2
Re ( e e i θ )
cos ( sin θ ) e cos θ (e e iθ
)=cos(sinθ)e cosθ
Re ( e e i θ )
cos ( cos θ ) e cos θ (e e iθ
)=cos(cosθ)e cosθ
