Answer 2

i tried merts and i got A

Answer 3

How did the cos^2 get into the numerator?

Answer 4

\[\frac{1-\sin \theta}{(1-\sin \theta)(1+\sin \theta)}+\frac{1+\sin \theta}{(1-\sin \theta)(1+\sin \theta)}=\]
\[\frac{2}{1-\sin ^2\theta}=\frac{2}{\cos ^2\theta}\]

Answer 5

Merts so than it will be A right

Answer 6

Do you think that these are the same:
1. \[2\cos ^2\theta \]
2. \[\frac{2}{\cos ^2\theta}\]

Answer 7

no:(

Answer 8

Then how could it be A?

Answer 9

I have clearly posted that the result is :
\[\frac{2}{\cos ^2\theta}\]
