284_Multiple and Line Integrals_[Ch. 7 c) X= k*x, Y = k*y, Z = k*z, where k = const (elastic force), and the initial point of the path is located on the sphere 2 x* 4- # + z 2 2 = /? Sec. 10. Surface Integrals , while the terminal point is located on the sphere 1. Surface integral of the first type. Let f (x, //, 2) be a continuous function and z=-cp(*, y) a smooth surface S. The surface integral of the first type is the limit of the integral sum .3 '(x, //, z)dS= lim n -> 00 fas I where AS/ is the area of the /th element of the surface S, the point (*/, y lt z/) belongs to this element, and the maximum diameter of elements of partition tends to zero. The value of this integral is not dependent on the choice of side of the surface S over which the integration is performed. If a projection a of the surface S on the jo/-plane is single-valued, that is, every straight line parallel to the z-axis intersects the surface S at only one point, then the appropriate surface integral of the first type may be calculated from the formula S (a) Example 1. Compute the surface integral (*' y) dx dl J- where S is the surf ace of the cube 0
Sec. 10] Surface Integrals 285 When we pass to the other side, S~, of the surface, this integral reverses sign. If the surface 5 is represented implicitly, F (x, y, z) = 0, then the direction cosines of the normal of this surface are determined from the formulas where 1 OF 1 Q dF 1 OF COSa==-pr^-, COSB -FT^ COS V = -rr- -T , T , D dz D dx ^ D dy and the choice of sign before the radical should be brought into agreement with the side of the surface S. 3. Stokes' formula. If the functions P = P (.v, //, z), Q = Q (x, //, z), R = R(x, y, z) are continuously differentiable and C is a closed contour bounding a two-sided surface S, we then have the Stokes' formula (j) C rr\fdR dQ\ Id? dR\ a , fdQ dP\ 1 _ = \ \ 3-- 1 5- c s a + -3 T- cos fi + 3-2- T- 1 cos v l ^ dS, JJ l\dy dz J ^\dt dx j 5 \dx dy J where cos a, cos p, cosy are the direction cosines of the normal to the surface S, and the direction of the normal is defined so that on the side of the normal the contour S is traced counterclockwise (in a rigiit-handed coordinate system). Evaluate the following surface integrals of the first type: 2347. $$ (* 8 4 tf)dS, where S is the sphere x z +// 2 -{-z 2 = a*. 6 2348. 5$ Vx 2 -\-tfdS where 5 is the lateral surface of the s . s cone + i==0 [O^z^bl g_?6 Evaluate the following surface integrals of the second type: 2349. \ \ yz dydz -\-xzdz dx-\- xydxdy, where 5 is the external s side of the surface of a tetrahedron bounded by the planes A: 0, y = Q t 2 = 0, x+y + z = a. 2350.
