from equation 1 ,
__
z = -i(w )
so arg[z] = 1arg[w] ----------------------(1)
from equation 2 ,
zw = pi
or,
arg(zw) = π2
arg[z] + arg[w] = π2 ----------------------(2)
solving (1) and (2) , we can get the answer
let z , w be complex nos. such that z + i ( conjugate of w ) = 0 and zw = pi . Then find arg z..
