Question

Tan A / (secan A -1) + tan A / (secan A + 1) =
​

Answer 1

Jawab:

2 . cosec A

Penjelasan dengan langkah-langkah:

(tan A / (secan A - 1)) + (tan A/(secan A + 1))

= (tan A . (secan A + 1) + tan A . (secan A - 1)) / (secan² A - 1)

= tan A . (secan A + 1 + secan A - 1) / tan² A

= 2 secan A / tan A

= 2/cos A . cos A/sin A

= 2/sin A

= 2 . cosec A
