The ratio of the greatest value of `2-cos x+s in^2x` to its least value is `7/4` (2) `9/4` (3) `(13)/4` (4) `5/4`

The ratio of the greatest value of 2-cos x+sin^2x to its least value is (1) 7/4 (2) 9/4 (3) (13)/4 (4) 5/4

The ratio of the greatest value of 2-cos x+sin^(2)x to its least value is (7)/(4)(2)(9)/(4)(3)(13)/(4)(4)(5)/(4)

Find the ratio of the greatest value of 2-cos x+sin^(2)x its least value is: (A)(1)/(4)(B)(9)/(4)(C)(13)/(4) (D) none of these
