TI - Elementary differential equations SN - 9814009792 AV - QA 371 .R35 1997 PY - 1997/// CY - Singapore PB - Prentice Hall International Inc. KW - DIFFERENTIAL EQUATIONS N1 - Includes index; 1. Definitions, families of curves -- 2. Equations of order one -- 3. Numerical methods -- 4. Elementary applications -- 5. Additional topics on equations of order one -- 6. Linear differential equations -- 7. Linear equations with constant coefficient -- 8. Nonhomogeneous equations -- 9. Variation of parameters -- 10. Applications N2 - The new geometric material appears mainly in Section 1.4 and 11.8. In the former we introduce students to the idea of a family of curves as solutions to a differential equation, and in the latter, the concept of the phase plane of a system of equations is presented ER -
