If $\sin^{-1}\Big(\frac{2\text{a}}{1-\text{a}^2}\Big)+\cos^{-1}\Big(\frac{1-\text{a}^2}{1+\text{a}^2}\Big)=\tan^{-1}\Big(\frac{2\text{x}}{1-\text{x}^2}\Big),$ where $\text{a},\text{x}\in(0,1),$ then the value of x is:
  1. $0$
  2. $\frac{\text{a}}{2}$
  3. $\text{a}$
  4. $\frac{2\text{a}}{1-\text{a}^2}$
