જો $0 < |x| < \sqrt 2$ માટે ${\sin ^{ - 1}}\left( {x - \frac{{{x^2}}}{2} + \frac{{{x^3}}}{4} - \dots} \right) + {\cos ^{ - 1}}\left( {{x^2} - \frac{{{x^4}}}{2} + \frac{{{x^6}}}{4} - \dots} \right) = \frac{\pi }{2}$ હોય,તો $x$ ની કિંમત શોધો.

  • A
    $1/2$
  • B
    $1$
  • C
    $-1/2$
  • D
    $-1$
