MA 341 Syllabus with Matlab/Maple

http://www4.ncsu.edu/eos/users/w/white/www/white/ma341/ma341hp.htm

 

This syllabus was used during the Spring 2001 semester by R. E. White, 515-7478, HA308, white@math.ncsu.edu.  The textbook was Differential Equations and Boundary Value Problems (Third Edition) by Nagle, Saff and Snider.  Below are links to transparencies, which are in 18 point font and about five slides were presented in the last 10 minutes of each lecture.  These transparencies are often associated with examples in this text.  They illustrate the use of Matlab/Maple calculations in ODEs, and when coupled with the one credit course MA 302 on Applications and Numerical Solution of ODEs, can empower the student with the necessary computational tools to solve nontrivial systems of differential equations.
