ODEs

Misc

• animation showing how phase plane for two real eigenvalues arises by rotating the case when eigendirections are orthogonal
• A more or less recent CNN article on the carrying capacity of the Earth
• Experimental results on predator-prey systems
• ODE Models for the Parachute Problem (article by Doug Meade, USC, SIAM Review 40(2) June 1998, pp. 327--332 has real data) (note: pdf file, so you need "acroread")
• Math Atlas: Diff Eqs
• applet for direction fields (use it!)
• maple help for ODEs:
  • 1-dim direction fields
  • 2-dim phase planes, and also how to plot solutions
  • info sheet used in math 244
  • list of tutorial sites
