here is ur answer buddy...
LHS,

(1-sin²A)/1+sin²A=cos²A/1+sin²A

RHS,

=>1/(Sec²A+tan²A)=1/{(1/cos²)+(sin²A/cos²A)}

=>1/{1+sin²A)/cos²

=>cos²/1-sin²A

LHS=RHS
HENCE PROVED

HOPE IT HELPS
IF POSSIBLE MARK ME AS BRAINLIEST

jude0704: cosA/sinA=2/1
jude0704: cosA/(1+sinA)=2sinA/1+sinA
jude0704: 2sinA+2
jude0704: sorry
jude0704: the correct one is
jude0704: sinA/1+cosA
jude0704: cross multiplication
jude0704: cosA(1+cosA)+sin²A/(sinA(1+cosA))
jude0704: (cosA+cos²A+sin²A)/sinA(1+cosA)
jude0704: the answer is √5/3
