A) Circle
B) a straight line
C) Parabola
D) none of these
Correct Answer: B
Solution :
\[\operatorname{Re}\left( \frac{z-2i+1-1}{z+1} \right)=1\]\[\Rightarrow \operatorname{Re}\left( \frac{-1-2i}{z+1}+1 \right)=1\]\[\Rightarrow \operatorname{Re}\left( \frac{-1-2i}{z+1} \right)=0\]\[\Rightarrow x+1+2y=0\]You need to login to perform this action.
