We will classify these equations into three different categories. If b2 ¡ 4ac > 0, we say the equation is hyperbolic. If b2 ¡ 4ac = 0, we say the equation is parabolic. If b2 ¡4ac < 0, we say the equation is elliptic. Example 1. † The wave equation utt ¡uxx = 0 is hyperbolic: † The Laplace equation uxx +uyy = 0 is elliptic: † The ...

For a parabolic equation, b2 −ac = 0 so equations (3) and (4) reduce to the same equation: A = 1 a [aξx + bξy] 2 (9) C = 1 a [aηx +bηy] 2 (10) Instead of two equations like (6) and (7) for hyperbolic equations, we have just the single equation aξx + bξy = 0 (or aηx + bηy = 0). Parabolic equations have only one family of characteristic ...

1. A differential equation of the form y0 =F(y) is autonomous. 2. That is, if the right side does not depend on x, the equation is autonomous. 3. Autonomous equations are separable, but ugly integrals and expressions that cannot be solved for y make qualitative analysis sensible. 4. The slopes in the direction field will only depend on y. 5.
