Directional Derivative of the Vector Field and Regular Curves on Time Scales |
| |
Abstract: | ![]() The general idea is to study curves where in the parametric equations the parameter varies in a so-called time scale, which may be an arbitrary dosed subset of the set of all real numbers. The directional derivative according to the vector fields was introduced. |

Keywords: | time scale nabla derivative regular curve tangent line vector field |
