Answer:
LHS = cosA / 1+sinA
= cosA (1-sinA) / (1+sinA)(1-sinA)
= cosA (1-sinA) / 1-sin^2A
= cosA (1-sinA) / cos^2A
= 1-sinA /cosA
RHS = 1-sinA / cosA
LHS = RHS

Step-by-step explanation:
LHS
= cosA / 1-sinA × 1+sinA / 1+sinA
= cosA (1+sinA) / (1-sinA) (1+sinA)
= cosA ( 1+sinA) / 1-sin^2A
= cosA (1+sin) / cos^2A
= ( 1+sinA) / cosA
= RHS
