6.
Prove that
(sec A- 1) - (1- cos A)
(sec A+ 1) (1 + cos A)

image answer preferred....please answer correctly✌️✨✨​

Answer 1

Step-by-step explanation:

(secA-1) /(secA+1)=[ (1-cosA) /cosA] ÷ [(1+cosA)/cosA]

=1-cosA/1+cosA

Answer 2

✍︎ANSWER✍︎

LHS : sᴇᴄ ᴀ - 1 / sᴇᴄ ᴀ + 1

➪ 1/ᴄᴏs ᴀ - 1 / 1/ ᴄᴏs ᴀ + 1

➪ 1 - ᴄᴏs ᴀ - 1/ ᴄᴏs ᴀ / 1 + ᴄᴏs ᴀ / ᴄᴏs ᴀ

➪ 1 - ᴄᴏs ᴀ / 1 + ᴄᴏs ᴀ.
