- 1. VECTOR CALCULUS BY ARJUNRASTOGI
- 2. DEFINITION • Vector calculus(or vector analysis) is a branch of mathematics concerned with differentiation and integration of vector fields, primarily in 3-dimensional Euclidean space
- 3. Basic objects • Scalarfields A scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number or a physical quantity • Vector fields A vector field is an assignment of a vector to each point in a subset of space. A vector field in the plane, for instance, can be visualized as a collection of arrows with a given magnitude and direction each attached to a point in the plane.
