Given the complex numbers \(A_{1}=6 / 30\) and \(A_{2}=4+j 5\),

(a) convert \(A_{1}\) to rectangular form;

(b) convert \(A_{2}\) to polar and exponential form;

(c) calculate \(A_{3}=\left(A_{1}+A_{2}ight)\), giving your answer in polar form;

(d) calculate \(A_{4}=\) \(A_{1} A_{2}\), giving your answer in rectangular form;

(e) calculate \(A_{5}=A_{1} /\left(A_{2}^{*}ight)\), giving your answer in exponential form.
