If ` z= 1/((1+i)(1-2i))` , then |z| is

If z = (1 + 2i)/(1 - (1 -i)^(2)) then find Arg z

If z=(1+2i)/(1-(1-i)^(2)), then arg (z) equals a.0 b.(pi)/(2) c.pi d .non of these

If z=(1+2i)/(1-(1-i)^2), then arg(z) equals a. 0 b. pi/2 c. pi d. non of these

If z=(1+2i)/(1-(1-i)^(2)) then arg (z).....

If |z - 1| = |z + 1| = |z - 2i|, then value of |z| is

If z_(1),z_(2),z_(3) are the vertices of triangle such that |z_(1)-i|=|z_(2)-i|=|z_(3)-i| and z_(1)+z_(2)=3i-z_(3) then area of triangle is

If z_(1)=2 + 7i and z_(2)=1- 5i , then verify that |z_(1) + z_(2)| le |z_(1)| + |z_(2)|

If z_(1)=2 + 7i and z_(2)=1- 5i , then verify that |(z_(1))/(z_(2))|= (|z_(1)|)/(|z_(2)|)
