1.If α=2tan−1(1+x1−x)\alpha = 2\tan^{-1}\left(\dfrac{1+x}{1-x}\right)α=2tan−1(1−x1+x) and β=sin−1(1−x21+x2)\beta = \sin^{-1}\left(\dfrac{1-x^2}{1+x^2}\right)β=sin−1(1+x21−x2), what is the value of α+β\alpha + \betaα+β if x>1x > 1x>1?a.−π-\pi−πb.π\piπc.π/2\pi/2π/2d.2π2\pi2πLogin to continueOnly logged in users canattempt or see the solution.
