9 ((z_3 −z_1 )/(z_2 −z_1 ))=+−i ⇒(z_3 −z_1 )^2 =−(z_2 −z_1 )^2 ⇒z_3 ^2 −2z_1 z_3 +z_1 ^2 =−z_2 ^2 −z_1 ^2 +2z_2 z_1 ⇒z_3 ^2 +2z_1 ^2 +z_2 ^2 =2(z_1 z_3 +z_1 z_2 )

9z3−z1z2−z1=+−i⇒(z3−z1)2=−(z2−z1)2⇒z32−2z1z3+z12=−z22−z12+2z2z1⇒z32+2z12+z22=2(z1z3+z1z2)

10) us_ e ((z_2 −0)/(z_1 −0))=e^(+_− i(π/3))

10)usez2−0z1−0=e+−iπ3

please sir.elaborate and where this ((z_2 −0)/(z_1 −0))=e^(±(π/3)) ?

pleasesir.elaborateandwherethisz2−0z1−0=e±π3?
