Vector Analysis: Basics[edit | edit source]
We are interested in operations on sets in a multidimensional space. The focus is on physical problems so think about three spatial dimensions, , and the dimension of time . For notation, I will use , and . This is easily scaled to - dimensions for larger spaces. So corresponds to for most of the time, or less.
Two types of fields[edit | edit source]
Scalar Field[edit | edit source]
A scalar x is a real number, this is denoted as . A vector in 3-D is a "3-tuple" of real numbers where for . Example:
