R-Rank Booster (2)

If

|z|2 + A(bar) z2 + A z(bar)2 + B(bar) z + B z(bar) + c=0

represents a pair of straight lines intersecting with angle θ, then the value of |A| is-

a) tanθ

b) cosθ

c) secθ

d) secθ/2

Sorry for the inconvenience, the latex is not working.

Let z=reiθ
A=raeiα
B=rbeiβ

Dividing through out the gven eqn by |z|2

+C+1=0

latex is turning out to be very difficult

This wen simplified using the above values and trignometry gives.........

2(racosα+rbrcosβ)eiθ+c+1=0

But finally............... what does this represent!!![5][5][5]???[7][7][7]
