જો $|x| < 1$ અને $y = x - \frac{x^2}{2} + \frac{x^3}{3} - \frac{x^4}{4} + \ldots$ હોય,તો $x$ ની કિંમત શું થાય?

  • A
    $y + \frac{y^2}{2!} + \frac{y^3}{3!} + \ldots$
  • B
    $y - \frac{y^2}{2!} + \frac{y^3}{3!} - \frac{y^4}{4!} + \ldots$
  • C
    $y + \frac{y^2}{2} + \frac{y^3}{3} + \ldots$
  • D
    $y - \frac{y^2}{2} + \frac{y^3}{3} - \frac{y^4}{4} + \ldots$
