If `0

1.	If `0
Answer» Correct Answer - 9 `1 + sin (cos^(-1) x) + sin^(2) (cos^(-1) x) + ...oo = 2` `rArr (1)/(1-sin (cos^(-1)x)) = 2` or `(1)/(2) = 1 - sin (cos^(-1) x)` or `sin (cos^(-1)x) = (1)/(2)` or `sin (cos^(-1) x) = (1)/(2)` or `cos^(-1) x = (pi)/(6)` or `x = (sqrt3)/(2) " or " 12x^(2) = 9`
