Question

cosecA = cotA / cosA​

Answer 1

Answer:

L. H. S = cosecA = 1/sinA

R. H. S = cotA / cosA [cotA = cosA/sinA]

= cosA/ sinA / cosA

= 1/sinA

Therefore, L. H. S = R. H. S (1/sinA = 1/sinA). PROVED

Answer 2

Step-by-step explanation:

To Prove:- CosecA = CotA/CosA

Proof:-

Taking RHS

CotA/CosA

= (CosA/SinA)/CosA

= 1/SinA

= Cosec A { By Identity CosecA = SinA }

Hence, CosecA=CosecA

LHS=RHS
