[" 7.) If "z_(1),z_(2)" are comple "x" numbers and if "],[|z_(1)+z_(2)|=|z_(1)|-|z_(2)|" show that "arg(z_(1))-arg(z_(2))=pi]

If z_(1) , z_(2) are complex numbers and if |z_(1) + z_(2)| = |z_(1)| - |z_(2)| show that arg (z_(1)) - arg (z_(2)) = pi .

If z_(1) , z_(2) are complex numbers and if |z_(1) + z_(2)| = |z_(1) - z_(2)| show that are (z_(1)) - arg (z_(2)) = pm (pi)/(2)

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

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

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

If z_(1), z_(2) are two non-zero complex numbers satisfying |z_(1)+z_(2)|=|z_(1)|+|z_(2)| , show that Arg z_(1) - Arg z_(2)=0

If z_(1), and z_(2) are the two complex numbers such that|z_(1)|=|z_(2)|+|z_(1)-z_(2)| then find arg(z_(1))-arg(z_(2))

|z_(1)|=|z_(2)|" and "arg z_(1)+argz_(2)=0 then
