Source sentences:
text: This equation says that the vector tangent to the curve at any point x(t) along the curve is precisely the vector F(x(t)), and so the curve x(t) is tangent at each point to the vector field F.
text: More specifically, two curves are said to be tangent at a point if they have the same tangent at a point, and orthogonal if their tangent lines are orthogonal.
text: This theorem is the key for the computation of essential geometric features of the curve: tangents, normals, and curvature.
