A complex number is given by `z=(1+2i)/(1-(1-i)^(2))`
What is the principal argument of z?

A complex number is given by z=(1+2i)/(1-(1-i)^(2)) What is the modulus of z ?

" If "z=((1+i)(1+2i)(1+3i))/((1-i)(2-i)(3-i))" then the principal argument of "z"

Principal argument of z=-1-i sqrt(3)

If a complex number z satisfies |2z+10+10 i|lt=5sqrt(3)-5, then the least principal argument of z is

If a complex number z satisfies |2z+10+10 i|lt=5sqrt(3)-5, then the least principal argument of z is

The principal argument of 2z^(2)+1-sqrt(3)i=0

Let z_(1) and z_(2) be two distinct complex numbers and z=(1-t)z_(1)+iz_(2) , for some real number t with 0 lt t lt 1 and i=sqrt(-1) . If arg(w) denotes the principal argument of a non-zero complex number w, then
