Basically, the vectors are defined by saying "we are doing the Directional derivative of any function along this direction".One thing to remember is that of course, the most convenient way to define a function and to specify a direction, is by using one of the coordinate charts.

The tangent space is the vector space of tangent vectors to a smooth manifold at . For a regular parametrized surface , it is spanned by and .
In mathematics, particularly in differential geometry, the concept of tangent space is fundamental to understanding the local properties of differentiable manifolds. ### Definition The **tangent space** at a point on a manifold is a vector space that consists of the tangent vectors at that point. Intuitively, you can think of it as the space of all possible directions in which you can tangentially pass through a given point on the manifold. ### Formal Construction 1.
