Answer:
Explanation:
cotA + tanA = secAcosecA
LHS=cotA + tanA
= +
take lcm of the denominator
=(COS^2A + sin^2A =1)
=
=1/sinA * 1/cosA
=cosecA*secA
=secAcosecA
therefore LHS=RHS
hence proved.
cotA + tanA
= cosA / sinA+ sinA/ cosA
= cos2A + sin2A / sinA* cosA
= 1 / sinA* cosA
=1/ sinA * 1/ cosA
= cosecA *secA
