Convert it into a+ib form:
`(7(cos135^(@)+isin135^(@)))/(14(cos90^(@)+isin90^(@)))`.

The value of (4(cos75^(@) + isin 75^(@)))/(0.4(cos30^(@) + i sin 30^(@))) is :

Evaluate cos135^(@)

Given that (2 sqrt3 cos 30^(@) - 2i sin 30^(@))/(sqrt2 (cos 45^(@) + isin 45^(@)))=A + Bi , find the values of A and B.

Convert the following angles into radians: a) 30^(@) b) 135^(@) c) 90^(@)

Give the following quotients in polar form: (9(cos90^0+isin90^0))/(3(cos45^0+isin45^0)

Re [((cos2^(@)+isin2^(@))^(100)(cos5^(@)+isin5^(@))^(200))/((cos10^(@)+isin10^(@))^(126))]

Write down the following complex number in polar form: Product of 2 (cos 30^0+isin 30^0) and 3 (cos 90^0+isin90^0)

Give the following products in polar form: [2(cos 210^0+isin210^0)][4(cos120^0+isin120^0)]

Evaluate : (cos 58 ^(@))/(sin 32^(@)) +(sin 22^(@))/(cos 68^(@)) - cos 90 ^(@)
