first of all change it into sin and cos this is ncert question u can get it on www.learncbse.in

Answer 2

Step-by-step explanation:

CotO + CosecO = 2

CosO/SinO + 1/SinO = 2

(1+CosO)/SinO = 2 --------(1)

(1+CosO/1-CosO)*(1+CosO/1+CosO)

(1+CosO)²/1-Cos²O

(1+CosO)²/Sin²O

{(1+CosO)/SinO}²

equation (1) Se

(2)² = 4 ans.
