Unformatted text preview: MATH 310 Fall 2011 Differential Equations Homework Exercises, Set 9 Quiz on Wednesday, 23 November 2011 Course Information is on WebCT . The quiz will be on the method of variation of parameters (first set of questions from Section 3.6) and the method of reduction of order from Section 3.4 (which you prepared for the last quiz, but which was not tested). Textbook references are to: Boyce and DiPrima Elementary Differential Equations and Boundary Value Problems (9th edition). Reading : Sections 3.4, 3.6, 3.7, 3.8, 7.1, 7.2, 7.3 Problems to prepare for quiz (no need to hand in): Section 3.6, # 3, 10, 13, 16, 19 Variation of parameters Section 3.6, # (21, 22, 23) Variation of parameters for a general nonhomogeneous term g ( t ) ; these problems (2123) are important for general theory, but will not be tested Formula (ii) in #23, the solution of y 00 + y = g ( t ) with zero ICs, is a special case of equation (i) in #27, which gives the form of the general solution for...
