Find the acute angle between the curves y = | x2 – 1| and y = | x2 – 3 | at their points of intersection when x > 0.
None of these
For the intersection of the given curves
we have point of intersection as
Here y = | x2 – 1| = (x2 – 1) in the neighbouring of
any y = –(x2 – 3) in the neighbouring of
hence, if θ is angle between them,
