Question

- tanto + costo >=2​

Answer 1

Answer:

- tanto + costo >=2 is the answer

Answer 2

tanA+cotA=2

From Prerequisite 1

tanA+1tanA=2

tan2A+1tanA=2

tan2A+1=2.tanA

tan2A−2.tanA+12=0

From Prerequisite 2

(tanA−1)2=0

tanA−1=0

tanA=1

cotA=1

So ,

tan7A+cot7A

(tanA)7+(cotA)7A

Putting value of tanA and cotA

1+1=2

HOPE IT HELPS

So answer is 2
