Let z be a complex number with ∣z∣=3 and Arg(z)=−32​π (a) Write down the Cartesian form of z. z= [You may give your answer in unsimplified form but remember to use Maple syntax to write your answer. For example, 2+3i would have to be entered as 2+3⋆I.] (b) Find the modulus and principal argument of z469 ∣∣​z469∣∣​= [ Your answer must be exact but you may enter it in unsimplified form ab.] Arg(z469)=
