Question

cosec2theta /cosec theta-1 - cosec2theta/cosec theta +1 =2 sec 2 theta ​

Answer 1

Answer:

By taking Cosec^2 θ Common  

(Cosecθ)^2(1/Cosecθ-1 -1/Cosecθ+1)

(Cosecθ)^2(Cosecθ+1-Cosecθ + 1)/(Cosecθ)^2 - 1

(Cosecθ)^2)(2)/(Cotθ)^2

2(Cosecθ)^2(Tanθ)^2

2(Cosecθ *Tanθ)^2

2(Cosecθ * Secθ / Cosecθ)^2

2(Sec)^2
