If `|z-3|=min{|z-1|,|z-5|}`, then `Re(z)` equals to

Let w ne pm 1 be a complex number. If |w|=1" and "z=(w-1)/(w+1) , then Re(z) is equal to

If |z-1|=|z-3| then the locus of z is

P(z) be a variable point in the Argand plane such that |z| =minimum {|z−1, |z+1|} , then z+barz will be equal to a. -1 or 1 b. 1 but not equal to-1 c. -1 but not equal to 1 d. none of these

If z_(1)" and "z_(2) are two non-zero complex numbers such that |z_(1)+z_(2)|=|z_1|+|z_(2)| , then arg ((z_1)/(z_2)) is equal to

If |z_1-1|lt=1,|z_2-2|lt=2,|z_(3)-3|lt=3, then find the greatest value of |z_1+z_2+z_3|dot

If z_(1)" and "z_(2) are two non-zero complex numbers such that |z_(1)+z_(2)|=|z_1|+|z_(2)| , then arg z_(1)- arg z_(2) is equal to

If |z|=1 and z'=(1+z^(2))/(z) , then

If |z_(1)+ z_(2)|=|z_(1)|+|z_(2)| , then arg z_(1) - arg z_(2) is

If |z-z_(1)|=|z-z_(2)| then the locus of z is :
