My teacher has told me to prove the identity for the i component and generalize for the j and k components. In vector (or multivariable) calculus, we will deal with functions of two or three variables (usually x,y or x,y,z, respectively). To build a theory of calculus for vector-valued functions, we simply treat each component of a vector-valued function as a regular, single-variable function. Some of the important concepts of the ordinary calculus are reviewed in Appendix B to this Chapter, §1.B.2. The curl of a vector function 3. R. Vector calculus identity. I need help concerning vector functions and indexing notations. Let a → be a (smooth) vector field and φ be a (smooth) scalar function. Show With this notation, the multivariable chain rule can be written more compactly as a dot product between the gradient of and the vector-derivative of : Written like this, the analogy with the single-variable derivative is clearer. 2.
