The Secant Method - USM

Jim Lambers MAT 772 Fall Semester 2010-11 Lecture 4 Notes These notes correspond to Sections 1.5 and 1.6 in the text. The Secant Method One drawback of Newton’s method is that it is necessary to evaluate f0(x) at various points, which may not be practical for some choices of f.

Properties of Sturm-Liouville Eigenfunctions and Eigenvalues

Real Eigenvalues Just as a symmetric matrix has real eigenvalues, so does a (self-adjoint) Sturm-Liouville operator. Proposition 2 The eigenvalues of a regular or periodic Sturm-Liouville problem are real.

The Wronskian - math.usm.edu

We de ne a second-order linear di erential operator Lby L[y] = y00+ p(t)y0+ q(t)y: Then, a initial value problem with a second-order homogeneous linear ODE can be stated as L[y] = 0; y(t 0) = y 0; y0(t 0) = z 0: We state a result concerning existence and uniqueness of solutions to such ODE, analogous to the Existence-Uniqueness Theorem for rst ...

Linear Interpolating Splines - USM

Linear Interpolating Splines We have seen that high-degree polynomial interpolation can be problematic. However, if the tting function is only required to have a few continuous derivatives, then one can construct a piecewise polynomial to t the data. We now precisely de ne what we mean by a piecewise polynomial.

Properties of Sturm-Liouville Eigenfunctions and …

The following essential result characterizes the behavior of the entire set of eigenvalues of Sturm-Liouville problems. Proposition 6 The set of eigenvalues of a regular Sturm-Liouville problem is countably in nite, and is a monotonically increasing sequence 0 < 1 < 2 < < n< n+1 < with lim n!1 n = 1. The same is true for a periodic Sturm ...

Orthogonality of Bessel Functions - USM

Orthogonality of Bessel Functions Since Bessel functions often appear in solutions of PDE, it is necessary to be able to compute coe cients of series whose terms include Bessel functions. Therefore, we need to understand their orthogonality properties. Consider the Bessel equation ˆ2 d2J (kˆ) dˆ2 + ˆ dJ (kˆ) dˆ + (k2ˆ2 2)J (kˆ) = 0 ...

ments three methods to solve boundary value prob-lems. The simplest solution method is the single shooting method, which combines initial value prob-lem integration with a nonlinear root finding algo-rithm (Press et al.,2007). Two more stable solu-tion methods implement a mono implicit Runge-Kutta (MIRK) code, based on the FORTRAN code
