$0 < \phi < \frac{\pi}{2}$ के लिए,यदि $x = \sum_{n=0}^\infty \cos^{2n}\phi$,$y = \sum_{n=0}^\infty \sin^{2n}\phi$,और $z = \sum_{n=0}^\infty \cos^{2n}\phi \sin^{2n}\phi$ है,तो:

  • A
    $xyz = xz + y$
  • B
    $xyz = xy + z$
  • C
    $xyz = x + y + z$
  • D
    $xyz = x + y + z$ और $xyz = xy + z$
