## Main Question or Discussion Point

**What is the difference between these two courses? ODE vs EDE???**

Hopefully this is the right place to ask.

Does anyone know the difference between these two courses? And which one I should take?

I'll be taking Linear Algebra (2nd semester of LA) with either one.

I haven't decided which one to take yet because these courses look the same....

Elementary Differential Equations I said:First-order equations; linear equations; linear systems; Laplace transforms; numerical methods; trajectory analysis of plane nonlinear systems. Applications of these topics will be emphasized.

Elementary Differential Equations II said:Power series methods (ordinary and regular singular points, Bessel's equation); boundary value problems and separation of variables (Fourier series and other orthogonal series), applications to the vibrating string, heat flow, potentials.

Ordinary Differential Equations said:Review of linear systems; nonlinear equations and applications; phase plane analysis; Laplace transforms; numerical methods

The thing is, other than Elementary Differential Equations II, all of the other courses have a "2xx" in them. For Elementary Differential Equations II, it says any of the three courses will serve as a prereq.Linear ordinary differential equations said:. Complex numbers, Laplace transforms, frequency reponse, resonance, step response, systems.

Thanks!
