1.2 Vector Components and Dummy Indices Let Abe a vector in R3. As the set fe^ igforms a basis for R3, the vector A may be written as a linear combination of the e^ i: A= A 1e^ 1 + A 2e^ 2 + A 3e^ 3: (1.13) The three numbers A i, i= 1;2;3, are called the (Cartesian) components of the vector A. We may rewrite Equation (1.13) using indices as ...
