Question

plz answer the question correctly​

Answer 1

the answer is in above pic

Answer 2

Step-by-step explanation:

cosA/(1-sinA) + (1-sinA)/cosA

Take LCM of the denominators,

= [cos²A + (1-sinA)²] / [(1-sinA)cosA]

= (cos²A + 1 + sin²A - 2sinA) / [ (1- sin A) cosA ]

= (1 + 1 - 2 sinA) / [ (1- sin A) cosA ]

= 2(1 - sinA) / (1-sinA) cosA

= 2 / cosA

= 2 cosecA

LHS = RHS

Hence, Proved.
