شرح Dr. Mohamed Walid:
Vector functions are mathematical functions that operate on vectors, which are quantities that have both magnitude and direction. These functions can be used to model physical phenomena, such as the motion of objects, the flow of fluids, and the behavior of electric and magnetic fields.
Examples of vector functions include position, velocity, and acceleration. These functions can be used to describe the motion of objects in three-dimensional space. Other vector functions include gradient, divergence, and curl, which are used in fields such as fluid mechanics and electromagnetism.
