1.	which of the following statement `is // are ` true ? (i) f(x) =sin x is increasing in interval `[(-pi)/(2),(pi)/(2)]` (ii) f(x) = sin x is increasing at all point of the interval `[(-pi)/(2),(pi)/(2)]` (3) f(x) = sin x is increasing in interval `((-pi)/(2),(pi)/(2)) UU ((3pi)/(2),(5pi)/(2))` (4) f(x)=sin x is increasing at all point of the interval `((-pi)/(2),(pi)/(2)) UU ((3pi)/(2),(5pi)/(2))` (5) f(x) = sin x is increasing in intervals `[(-pi)/(2),(pi)/(2)]& [(3pi)/(2),(5pi)/(2)]`A. all are correctB. all are falseC. (3) and (4) are correctD. (1),(4) & (5) are correct
