complxin lyf :P

if z is a complex no lyin in d foruth qudrnt of d argnd plane and mod (kz/(k+1) +2i) > 2
for all eal values of k (k=!-1) then d range of arg(z) is

z₁ = kz/k+1

is a line between origin and z for different values of k

so it will give lines y=mx

now we have to find the points for which the distance from (0,-2) is always greater than root 2 in the 4th quadrant...

if u draw the graph it will come in a flash :)
