Options

  1. AIf (a + 2 bcosx ) ( a - 2 bcosy) = a ^ 2 - b ^ 2 , where a > b > 0, then (dx)/(dy) at ((π)/(4), (π)/(4)) is:
  2. BIf (a + 2 bcosx ) ( a - 2 bcosy) = a ^ 2 - b ^ 2 , where a > b > 0, then (dx)/(dy) at ((π)/(4), (π)/(4)) is:
  3. CIf (a + 2 bcosx ) ( a - 2 bcosy) = a ^ 2 - b ^ 2 , where a > b > 0, then (dx)/(dy) at ((π)/(4), (π)/(4)) is:
  4. DIf (a + 2 bcosx ) ( a - 2 bcosy) = a ^ 2 - b ^ 2 , where a > b > 0, then (dx)/(dy) at ((π)/(4), (π)/(4)) is:

Correct answer

D. If (a + 2 bcosx ) ( a - 2 bcosy) = a ^ 2 - b ^ 2 , where a > b > 0, then (dx)/(dy) at ((π)/(4), (π)/(4)) is:

Step-by-step solution

(i) phenol gives test with neutral FeCl3FeC{l}_{3}.
(ii) aldehyde gives Fehling test.
(iii) An organic compound neither reacts with neutral ferric chloride solution nor with Fehling solution. It however, reacts group gives iodoform test.
(iv) Grignard reagent gives test with acidic hydrogen.
An organic compound neither reacts with neutral ferric chloride solution nor with Fehling solution. It however, reacts
