Question

Z=x+iy then the equation |2z-i|/|z+1|=m does not represents a circle

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Let us solve this problem via geometrical approach

Step-by-step explanation:

|z-i/2| = m/2||z+1| will represent a st. line if m/2 equals 1

Hence the value of m = 2.
