Consider the following statements:

1. If a line has direction ratios 1, 1, 2, then its direction cosines are \(\frac{1}{\sqrt{6}},\frac{1}{\sqrt{6}},\frac{2}{\sqrt{6}}\)

2. The angle between the line whose direction ratios are (1, 1, 2), \((\sqrt{3},-\sqrt{3},0)\) is 60^o

3. The direction cosines of the vector joining the points A(1, 2, -3) and B(-1, -2, 1), directed from A to B is \(-\frac{1}{3},-\frac{2}{3},-\frac{2}{3}\)

Which of the above statements is/are correct?
