Answer:
proof
Step-by-step explanation:
sec theta + tan theta
= 1/cos theta + sin theta / cos theta
= 1 + sin theta / cos theta
= ( 1+sin theta ) cos theta / cos^2 theta
= ( 1+sin theta ) cos theta/ ( 1 - sin^2 theta)
= ( 1+sin theta ) cos theta/ ( 1 + sin theta) ( 1 - sin theta)
= cos theta / 1 - sin theta
= RHS
