JEE MainMathematicsSets and RelationsMCQ+4 / −1
Define a relation R on the interval [0,π2)\left[0, \frac{\pi}{2}\right)[0,2π​) by xxx R yyy if and only if sec⁡2x−tan⁡2y=1\sec^2x - \tan^2y = 1sec2x−tan2y=1. Then R is :
  1. A
    both reflexive and symmetric but not transitive
  2. B
    both reflexive and transitive but not symmetric
  3. C
    reflexive but neither symmetric not transitive
  4. D
    an equivalence relation
