Answer 2

Answer:

so u have to use identities to solve LHS

let me help u out by step by step explanation

Step-by-step explanation:

1 - cosA / 1 + cosA = ( cosA - cossecA)²

TAKING R H S

= cotA² - 2cotA + CossecA + cos²x

{ by (a-b)² = a² + b² -2ab }

= cos²A / sin²A - 2cosA / sin² + 1/sin²A

= cos²A - 2cosA + 1 / 1 - cos²A

= (1-cos A) (1-cosA) / (1+cosA) (1-cosA)

{ ye isliae kia kyuki bhai tune dekha hoga ki aek possibility hoti hai ki denominator me joh value give hoti hai uskae opposite value means agar + mei hai toh - mei numerator or denominator me value sae mutiply krdo }

= (1-cosA) / (1+cosA)

= LHS = RHS

hence, proved !!

bruh !! this is the correct answer
