Review of Basic Differential Equations

The prerequesite for MATH 405 is MATH 305, Introduction to Differential Equations. Fortunately, not all the material is needed for MATH 405. Here are links to my lecture notes for MATH 305 that should be sufficient for MATH 405.

• Separable, Linear, Applications, Theory and Slope Fields
• Real Roots (Sections 3.1, 3,2 and 3.4)
• Reduction of Order (Section 3.4)
• Complex Roots (Section 3.3)
• The Theory (Section 3.2)
• Undermined Coefficients (Section 3.5)
• Table for 3.5
• Variation of Parameters (Section 3.6)
• Higher Order Equations (Chapter 4)
