This WebThe aim of this section is to introduce the tangent bundle TXfor a diﬀerential manifold X. Intuitively this is the object we get by gluing at each point p∈ Xthe corresponding tangent space TpX. The diﬀerentiable structure on Xinduces a diﬀerentiable structure on TXmaking it into a diﬀerentiable manifold of dimension 2dim(X).
