1 Parametrized Surfaces Recall from our unit on vector-valued functions at the beginning of the semester that an R 3 -valued function c(t) in one parameter is a mapping of the form c : I R 3 where I is some subinterval of the real line. If c is differentiable, we can think of c as smoothly embedding the interval I as a closed curve C in R 3, a parametrized curve.
2 Parametrized Surfaces Recall from our unit on vector-valued functions at the beginning of the semester that an R 3 -valued function c(t) in one parameter is a mapping of the form c : I R 3 where I is some subinterval of the real line. If c is differentiable, we can think of c as smoothly embedding the interval I as a closed curve C in R 3, a parametrized curve. Our goal now is to study parametrized surfaces, which are a natural next step from parametrized curves. Now instead of embedding a 1-dimensional domain I into R 3, we will embed 2-dimensional domain D into R 3 and do calculus on the embedded surface.
3 Definition We consider a continuously differentiable R 3 -valued function of two variables G : R 2 R 3 : G(u, v) = (x(u, v), y(u, v), z(u, v))
4 Definition We consider a continuously differentiable R 3 -valued function of two variables G : R 2 R 3 : The graph of G is the set G(u, v) = (x(u, v), y(u, v), z(u, v)) {(x, y, z) R 3 : there exists (u, v) with G(u, v) = (x, y, z)}. (This definition is analogous to that of the graph of a vector-valued function.) The graph of G is also called a parametrized surface. The domain D of G is called the parameter domain.
5 Example (Parametrization of a Sphere) Fix any R > 0. Let D = [0, 2π] [0, π], a rectangle in R 2. Define a mapping G on D by G(θ, φ) = (R cos θ sin φ, R sin θ sin φ, R cos φ). Then G maps D onto the sphere of radius R in R 3.
6 Example (Parametrization of the Graph of a Real-Valued Function of Two Variables) Let f (x, y) be any real-valued function of two variables with domain D. Define mapping G on D by G(x, y) = (x, y, f (x, y)). Then G maps D onto the graph of f. (In particular the graph of G equals the graph of f.)
7 Definition Let G(u, v) = (x, y, z) be a continuously differentiable R 3 -valued function of two variables. Define the u-tangent vector and the v-tangent vector functions of G, respectively, to be T u = (x u, y u, z u ) and T v = (x v, y v, z v ). T u and T v are both functions from R 2 into R 3, and they output non-parallel tangent vectors to the graph of G at input (u, v).
8 Definition Let G(u, v) = (x, y, z) be a continuously differentiable R 3 -valued function of two variables. Define the u-tangent vector and the v-tangent vector functions of G, respectively, to be T u = (x u, y u, z u ) and T v = (x v, y v, z v ). T u and T v are both functions from R 2 into R 3, and they output non-parallel tangent vectors to the graph of G at input (u, v). Assume both T u and T v are non-zero. Define the normal vector associated to G to be the function n = T u T v. Then n is always orthogonal to the tangent plane of the graph of G at a point G(u, v).
9 Example Let G(θ, z) = (2 cos θ, 2 sin θ, z) be a parametrization of the cylinder described by x 2 + y 2 = Compute T θ, T z, and n. 2. Find an equation for the tangent plane to the graph of G at G( π 4, 5).
10 Solution to (1) Known: G(θ, z) = (2 cos θ, 2 sin θ, z)
11 Solution to (1) Known: G(θ, z) = (2 cos θ, 2 sin θ, z) Taking derivatives, we have and hence T θ (θ, z) = ( 2 sin θ, 2 cos θ, 0) and T z = (0, 0, 1), n(θ, z) = T θ T z = det [ i j k 2 sin θ 2 cos θ ] = (2 cos θ, 2 sin θ, 0).
12 Solution to (2) Known: G(θ, z) = (2 cos θ, 2 sin θ, z) n = (2 cos θ, 2 sin θ, 0)
13 Solution to (2) Known: G(θ, z) = (2 cos θ, 2 sin θ, z) n = (2 cos θ, 2 sin θ, 0) To find the tangent plane, compute the normal at input ( π 4, 5): n( π 4, 5) = (2 cos π 4, 2 sin π 4, 0) = ( 2, 2, 0). The tangent plane passes through the point G( π 4, 5) = ( 2, 2, 5), and so its equation [using 0 = n ((x, y, z) (x 0, y 0, z 0 ))] is given by 0 = 2(x 2) + 2(y 2).
14 Surface Integrals Definition Let G(u, v) = (x, y, z) be a one-to-one continuously differentiable parametrization of a surface S in R 3 with domain D, with non-zero tangent vectors T u and T v. Let f (x, y, z) be a real-valued function of three variables. Define the surface integral of f over S to be S f (x, y, z)ds = f (G(u, v)) n(u, v) d(u, v). D
15 Surface Integrals Definition Let G(u, v) = (x, y, z) be a one-to-one continuously differentiable parametrization of a surface S in R 3 with domain D, with non-zero tangent vectors T u and T v. Let f (x, y, z) be a real-valued function of three variables. Define the surface integral of f over S to be S f (x, y, z)ds = D f (G(u, v)) n(u, v) d(u, v). Fact If G is as above, then the surface integral 1dS is exactly the surface S area of the graph of G.
16 Example 1. Calculate the surface area of the portion S of the cone x 2 + y 2 = z 2 within the cylinder x 2 + y 2 = For the same S, calculate S x 2 zds.
17 Surface Area of S First we parametrize the cone by G using a variant of spherical coordinates: G(ρ, θ) = (x, y, z) ( = ρ cos θ sin π 4, ρ sin θ sin π 4, ρ cos π ) 4 ( ) = ρ cos θ, sin θ, ρ on the domain D = [0, 2 2] [0, 2π] in the (ρ, θ)-plane.

26 Fact Suppose g(x, y) is a function of two variables let S be the graph of g. Suppose G(x, y) is a parametrization of S. Then T x = (1, 0, g x) and T y = (0, 1, g y ); n = 1 + g 2 x + g 2 y ;
27 Fact Suppose g(x, y) is a function of two variables let S be the graph of g. Suppose G(x, y) is a parametrization of S. Then T x = (1, 0, g x) and T y = (0, 1, g y ); n = 1 + g 2 x + g 2 y ; and therefore for any function f with domain S we have S f (x, y, z)ds = D f (x, y, g(x, y)) 1 + g 2 x + g 2 y d(x, y).
28 Proof. Let g(x, y) be a function. Then the graph of g is parametrized by G(u, v) = (x, y, z) = (u, v, g(u, v)).
29 Proof. Let g(x, y) be a function. Then the graph of g is parametrized by Computing tangent vectors, we have G(u, v) = (x, y, z) = (u, v, g(u, v)). T u = (1, 0, g x(u, v)) and T v (0, 1, g y (u, v))
30 Proof. Let g(x, y) be a function. Then the graph of g is parametrized by Computing tangent vectors, we have G(u, v) = (x, y, z) = (u, v, g(u, v)). T u = (1, 0, g x(u, v)) and T v (0, 1, g y (u, v)) and hence n = det i j k 1 0 g x(u, v) 0 1 g y (u, v) n = ( 1 + g 2 x + g 2 y ). = ( g x, g y, 1) and
31 Proof. Let g(x, y) be a function. Then the graph of g is parametrized by Computing tangent vectors, we have G(u, v) = (x, y, z) = (u, v, g(u, v)). T u = (1, 0, g x(u, v)) and T v (0, 1, g y (u, v)) and hence n = det i j k 1 0 g x(u, v) 0 1 g y (u, v) n = ( 1 + g 2 x + g 2 y ). = ( g x, g y, 1) and Therefore if we want to compute the surface integral of f over the graph of g, we get S f (x, y, z)ds = D f (x, y, g(x, y)) 1 + g 2 x + g 2 y d(x, y).
32 Example Compute S (z x)ds, where S is the graph of z = x + y 2, 0 x y, 0 y 1.
33 Example Compute S (z x)ds, where S is the graph of z = x + y 2, 0 x y, 0 y 1. Solution. Take g(x, y) = x + y 2, so n = (2y) 2 = 2 + 4y 2 )
34 Example Compute S (z x)ds, where S is the graph of z = x + y 2, 0 x y, 0 y 1. Solution. Take g(x, y) = x + y 2, so n = (2y) 2 = 2 + 4y 2 ) and f (x, y, g(x, y) = g(x, y) x = x + y 2 x = y 2.
35 Example Compute S (z x)ds, where S is the graph of z = x + y 2, 0 x y, 0 y 1. Solution. Take g(x, y) = x + y 2, so n = (2y) 2 = 2 + 4y 2 ) and f (x, y, g(x, y) = g(x, y) x = x + y 2 x = y 2. Now compute (using substitution rule with u = 2 + 4y 2 ): S (z x)ds = = 1 y y y 2 dxdy y y 2 dy = 1 30 ( ).

Definition Let G(u, v) be a parametrization of the surface S in R 3, and let n be its associated normal vector. Let F be a vector field over R 3. The normal component of F with respect to G is F n. Informally speaking, the normal component of F is how much of the vector field F is orthogonal to the surface S. The flux integral or vector surface integral S F ds of F across S is the surface integral of the normal component of F, i.e. S F ds = S ( F n)ds.
40 Fact Let G, S, n, F be as in the previous definition, and let D be the domain of G. Then S F ds = D F (G(u, v)) n(u, v)d(u, v). To help remember the formula, note the analogy here: computationally, flux integrals are to surface integrals as vector field line integrals are to scalar line integrals.
