यदि $\sin x + \cos x = a$,जहाँ $a \in [-\sqrt{2}, \sqrt{2}] - \{-1, 1\}$,तो $\sum_{n=1}^{\infty} (\sin^n x + \cos^n x)$ का मान ज्ञात कीजिए।

  • A
    $\frac{2(1 + a - a^2)}{(a + 1)^2}$
  • B
    $\frac{2(a^2 - a + 1)}{(a - 1)^2}$
  • C
    $\frac{2(a^2 - a + 1)}{(a + 1)^2}$
  • D
    $\frac{2(1 + a - a^2)}{(a - 1)^2}$
