Orientable manifold
Not what you're looking for?
I need to prove that the tangent bundle of a differentiable manifold is orientable even if the manifold is not. From class, all I know is that a manifold is orientable if it has an atlas {(Ua,xa)} such that when xa(Ua) intersected with xb(Ub) is non-empty then d(xb^(-1) composed with xa) has a positive determinant.
