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.
[hope you got that.]
Thanks!
