If f x = ∫ 0 x t sin x - sin t d t , then

f ''' x + f ' x = cos x - 2 x sin x

f ''' x - f '' x = cos x - 2 x sin x

f ''' x + f '' x - f ' x = cos x

Let f : R → R be a continuous function satisfying f x + ∫ 0 x t f t d t + x 2 = 0 . For all x ∈ R . Then-

f x has more than one point in common with the x -axis

A function f is continuous for all x (and not everywhere zero) such that f 2 x = ∫ 0 x f t cost 2 + sin t d t then f x is:

1 2 log e 2 + sin x 2 ; x ≠ n π , n ∈ I

1 2 log e x + cos x 2 ; x ≠ 0

1 2 log e 3 2 + cos x ; x ≠ 0
