If `asin^2x+bcos^2x=c,bsin^2y+acos^2y=d` and `atanx=btany` then `a^2/b^2=........ (0ltx,yltpi/ 2)`.............. A) `((b-c) (d-b))/((a-d) (c-a))` B) `((a-d ) (c-a))/((b-c) (d-b))` C) `((d-a) (c-a))/((b-c)(d-b))` D) `((b-c) (d-b))/((c-a) (a-d))`

A

`((b-c) (d-b))/((a-d) (c-a))`

B

`((a-d ) (c-a))/((b-c) (d-b))`
