# COSC 450 Applied Numerical Methods Syllabus

## I. Catalog Description

COSC 450 Applied Numerical Methods

3c-01-3sh

Prerequisite: COSC 250, MATH 171, and MATH 241 or equivalents

Polynomial approximations using finite differences, with applications in numerical integration and differentiation. Numerical solution of initial value ordinary differential equations. The APL language will be introduced and used along with Fortran, in programming selected algorithms.

## II. Course Objectives

1. Students should be able to use the APL language to implement numerical algorithms.
2. Students should be able to use polynomial approximation techniques in solving problems.
3. Students should be able to find numerical solutions of initial value ordinary differential equations.
