निम्नलिखित को ध्रुवीय रूप में प्रदर्शित कीजिए:
`[2(cos210^(@)+isin210^(@))][4(cos120^(@)+isin120^(@))]`

The value of (2(cos 75^(@) + isin 75^(@)))/(0.2(cos 30^(@) + isin 30^(@))) is

Give the following in polar form : [2(cos 210^@ + i sin 210^@)] [4(cos 120^@+i sin 120^@)] .

Give the following in polar form: (i) sin120^(@)-icos120^(@) (ii) [2cos210^(@)+isin210^(@))][4(cos120^(@)+isin120^(@))] (iii) [3(cos225^(@)+isin225^(@))][6(cos45^(@)+isin45^(@))] .

Find the value of sin330^(@)cos120^(@)+cos210^(@)sin300^(@)
