\int [a(\dot{b}\cdot a + b\cdot\dot{a}) + \dot{a}(b\cdot a) - 2(\dot{a}\cdot a)b - \dot{b}|a|^2]\, dt
[/tex]
The above are all vectors. How would one go about integrating this, the answer is apparently
[tex]
a \times (a \times b) + h
[/tex]
where h is a constant vector
I don't quite see how they arrive at this answer...
