Answer 1

Answer:

Step-by-step explanation:

1/Cos theta + sin theta / cos theta

-------------------------------------------------

1/cos theta - sin theta / cos theta

1 + sin theta

------------------

1 - sin theta

(1 + sin theta)(1 + sin theta)

-------------------------------------

(1 - sin theta )(1 - sin theta)

(1 + sin theta)(1 + sin theta)

--------------------------------------

1 - 2 sin theta + sin^2 theta

= (1 + sin theta)^2

---------------------------

Cos ^2 theta
