Give the following quotients in polar form: (i) (9(cos90^(@)+isin90^(@)))/(3(cos45^(@)+isin45^(@))) (ii) (7(cos135^(@)+isin135^(@)))/(14(cos90^(@)+isin90^(@))) .

(cos(pi/6)+isin(pi/6))^7=?

(sin150^(0)-5cos300^(0)+7tan225^(0))/(tan135^(0)+3sin210^(0))=

7(cos((-5pi)/6)+isin((-5pi)/6))=?

z=5(cos((7pi)/6)+isin((7pi)/6))=?

If z=cos30^@+isin30^@ , find z^7
