Question

(1+ tan2A) cotA/ Cosec2A
=
tan A​

Answer 1

Answer:

(1++tan 2A)cot A /Cosec 2A=tan A

= sec^2A.cot^2A/cosec^2A=tanA

= 1/cos^2A.cosA/sinA /1/sin^2A

= sin^2A/sinA.cosA

= sinA/cosA

= tanA

Answer 2

Answer:

( (1+tan^2 A) cot A ) /cosec^2 A

= ( sec^2 A × cot A ) /cosec^2 A

= ( sec^2 A / cosec^2 A ) × cot A

= tan^2 A × cot A

= tan A
