If asin^(2)x + bcos^(2)x = cbsin^(2)y + ...

If `asin^(2)x + bcos^(2)x = c``bsin^(2)y + acos^(2)y = d` and `atanx = btany`, then `a^(2)/b^(2)` equals :

A

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

B

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

C

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

D

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