Tangent Space


Let x be a point in an n-dimensional compact manifold M, and attach at x a copy of R^n tangential to M. The resulting structure is called the tangent space of M at x and is denoted T_xM. If gamma is a smooth curve passing through x, then the derivative of gamma at x is a vector in T_xM.
