Ch. 14.9 Parameterized Surfaces 1. Parameterization is usually done when one of the variables can be represented as either a constant or a function of the other two variables. In these cases, the constant or function is substituted for the third variable yielding a function of two variables. 2. For a surface parameterized by the area of the surface is described by a. 15.1 1. Basic Identities a. b. c. d. 2. A vector field representing the gradient of some function f has a curl of 0 15.2 1. The line integral of a function f(x,y,z) along the curve C can be rewritten using a parameterization of the curve C by an arbitrary variable t a. 2. The line integr
