Question

(1 + tan²A) cot A / cosec²A = tan A
prove it..​

Answer 1

Answer:

hi! here's the solution. Hope u mark me as the brainiest:)

Step-by-step explanation:

(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
