Answer:
1/4 +cos^2teta
Step-by-step explanation:
we know that sin 30 is 1/2, which u square and get 1/4
but for cos. we don't know the cat value of her a. there it stays same or you can write the equation in sin. like cos ^2teta= 1-sin^2teta
therefore it would be 1/4+1-sin^2(teta)
=5/4 -sin^2( teta)
