Question

plzzz anwer with clear explanation ​

Answer 1

Answer:

LHS,

convert into sin and cos

1- sin²/cos² / 1 + sin²/cos²

cos²-sin²/cos² / cos²+sin²/cos²

cos²-sin²/cos² * cos²                                   (cos²+sin²=1)

⇒cos²-sin²

1-sin²-sin²                                                      (cos²=1-sin²)

1-2sin²= RHS
