Question

(1+sin theta)(1-sin theta)/cos2theta​

Answer 1

Answer:

1

Step-by-step explanation:

(1+sin theta)(1-sin theta)/cos^2 theta

= ( 1 - sin^2 theta )/ cos^2 theta

= 1 - (1 - cos^2 theta) / cos^2 theta

= cos^2 theta/ cos^2 theta

=1

Answer 2

Answer:

(1+sin theeta)(1-sin theeta)/cos^2theeta

=(1-sin^2theeta)/cos^2theeta

=cos^2theet/cos^2theeta

=1
