Question

1/1+sin²A+1/1+cosec²A=1​

Answer 1

(1/1+sin^2 A)/(1/1+cosec^2 A)=

(1+cosec^2 A)+(1+sin^2 A)

____________________________=

(1+sin^2 A)(1+cosec^2 A

2+(1/sin^2 A)+sin^2 A

________________________

1+(1/sin^2 A)+sin^2 A+ sin^2 A x 1/sin^2A

=2+(1/sin^2 A)+sin^2 A

_________________________ =1

2+(1/sin^2 A)+sin^2 A
