# Math 410: Intro to Numerical Methods

### Title

Introduction to Numerical Methods.

(3:3:0)

F

### Description

Root finding, interpolation, curve fitting, numerical differentiation and integration, multiple integrals, direct solvers for linear systems, least squares, rational approximations, Fourier and other orthogonal methods. [This official course description appears to differ with current standard practice, in that iterative solvers of linear systems are taught in this course, while "Fourier and other orthogonal methods" are postponed until Math 411.]

## Desired Learning Outcomes

### Prerequisites

Students are required to have had multivariable calculus.

### Minimal learning outcomes

Students should be able to describe, derive, and implement the numerical methods listed below. They should be able to explain the advantages and disadvantages of each method. They should understand error analysis and be able to make practical decisions based on the outcomes of that analysis.

1. Numerical solution of equations of one variable
• Bisection method
• Secant method
• Fixed-point iteration
• Newton's method
• Error analysis
• Polynomial equations
2. Interpolation
• Lagrange interpolation
• Divided-difference methods
• Hermite interpolation
• Cubic spline interpolation
3. Numerical differentiation
• Derivation of formulas
