The general solution of d2u/dx2 = 0 is again an arbitrary straight line, u=C1x+C2. 17) The boundary conditions imply that the slope must be zero at both ends. 16), as illustrated in Fig. 2. 2 Various constant x=0 x=L equilibrium temperature distributions (with insulated ends). The solution is any constant temperature. 17), du/dx = Cl and both boundary conditions imply C1 = 0. 18) Chapter 1. Heat Equation 18 for any constant C2. Unlike the first example (with fixed temperatures at both ends), here there is not a unique equilibrium temperature.

29) dxi + dyj + dzk represents any vector in the tangent plane of the level surface. 29), its dot product with Vu is zero; that is, Vu is perpendicular to the tangent plane. Thus, Vu is perpendicular to the surface u = constant. 34 Chapter 1. Heat Equation We have thus learned two properties of the gradient, Vu: 1. Direction: Vu is perpendicular to the surface u = constant. Vu is also in the direction of the largest directional derivative. ) 2. Magnitude: IVul is the largest value of the directional derivative.

Later (Sec. 3) we will formulate a theory, involving the Rayleigh quotient, in which we will know before we start rFiany problems that there Chapter 2. 2 Hyperbolic functions. cannot be negative eigenvalues. This will at times eliminate calculations such as the ones just performed. Elgenfunctions-summary. We summarize our results for the boundary value problem resulting from separation of variables: 0(0) =0 ¢(L) = 0. This boundary value problem will arise many times in the text. It is helpful to nearly memorize the result that the eigen values A are all positive (not zero or negative), where n is any positive integer, n = 1 , 2, 3, ...
