\sqrt{1-c^2}=n c-1

and

z=e^{i \theta}

, then

\frac{c}{2 n}(1+n z)\left(1+\frac{n}{z}\right)

is equal to

View answer and explanation

Correct option: C

1+c \ cos \theta

Option C (

1+c \cos \theta

) is the correct answer because after simplification and using the given equation, the expression reduces to

1+c \cos \theta
