None of the Schaum's problems are initial value problems. I will put some initial value conditions for some of the Schaum's problems of each type over the next couple of days in case you feel you need more practice. Here is a summary of the techniques for SOLHODEWCCs Schaum's Chapter 9 problem types: Distinct, Real Roots: 1,3,5,17,18,22,27,28,29,32 Complex Roots: 7,8,9,10,11,20,21,24,31 Repeated Roots: 12,13,14,15,18,23,26,30 ----------------------------------------------------------- We will have our third exam over SOLHODEWCCs (HW17 - HW19) on Tuesday, 4/19. The exam will cover each type of SOLHODEWCC we have studied. You may bring up to 4 pages of study notes! ----------------------------------------------------------- Some sample IVC problems from Schaum's Chapter 9: 1) For problem 18, let y(0) = -5 and y'(0) = 9. Find c1 and c2 in the solution. 2) For problem 30, let y(0) = 50 and y'(0) = -249.3. Find c1 and c2 in the solution. 3) For problem 24, let y(0) = 5 and y'(0) = -12.0711. Find c1 and c2 in the solution. ----------------------------------------------------------- HW20: Method of Undetermined Coefficients (Paul's pgs 138-154 Do example 8a-e on page 150 of Paul's. Try these problems from Schaum's, chapter 11, pgs 94ff: 15,16,19,21,22,23,25,43,45,50,51 R&S pgs 155-160 in Paul's Due: Start of class on Tuesday, 4/26 ----------------------------------------------------------- HW21: Variation of Parameters Be able to do the following Examples from pgs 158-160 of our text: Examples 1,2,3 Do the following problems from Schaum's: 12.3, 12.4, 12.5, 12.9, 12.11, 12.12, 12.13 Due: Start of class, Thursday, 4/28 ----------------------------------------------------------- Final Exam Material: One undetermined coefficients IVC problem (from HW20 problems). One problem similar to Paul's Example 8, pg 147. One variation of parameters IVC problem (from HW21 problems). One variation of parameters with the Yc given to you, (like Paul's examples 1 and 2 on pgs 158-159. One application problem, choose from either the mixture or population problem.
