Since we will not have time to address substitutions in 1st order ODEs before HW2 is due, please do just problems 1-7. The due date for HW2 remains 02/06/2014 in recitation. * 01/24/2014: Changed homework due dates on [[gibson:teaching:spring-2014:math527:syllabus]] to Thursdays in recitation, and revised number of points off for missing or illegible names, etc. on [[gibson:teaching:spring-2014:math527:policies]]. * 01/21/2014: You are responsible for reading and understanding the course [[gibson:teaching:spring-2014:math527:policies]] and [[gibson:teaching:spring-2014:math527:syllabus]]. * 01/21/2014: Add/drop forms for this course are approved and signed by the Math Dept office, W383 Kingsbury Hall. The instructor and TAs cannot sign these forms. ===== Homework ===== [[:gibson:teaching:spring-2014:math527:policies#homework|Homework policies.]] Homeworks are due most Thursdays in recitation. ^ homework ^ due ^ solutions ^ topic ^ notes ^ | {{:gibson:teaching:spring-2014:math527:hw1.pdf|HW1}} | 01/30 |{{:gibson:teaching:spring-2014:math527:hw1-solns.pdf|HW1 solns}} | separable & 1st order linear | | | {{:gibson:teaching:spring-2014:math527:hw2.pdf|HW2}} | 02/06 |{{:gibson:teaching:spring-2014:math527:2014-differential-equations-hw-2-solutions.pdf| HW2 solns}} | exact equations & substitutions | **don't do problems 8-10** | | {{:gibson:teaching:spring-2014:math527:hw3.pdf|HW3}} | 02/20 | {{:gibson:teaching:spring-2014:math527:hw3sols.pdf|HW3 solns}} | 2nd-order const coeff homogeneous, reduction of order | problem 10: assume <latex> \alpha^2 - 4 \beta > 0 </latex> | | {{:gibson:teaching:spring-2014:math527:hw4.pdf|HW4}} | 02/27 |{{:gibson:teaching:spring-2014:math527:2014-spring-differential-equations-hw-4-solutions.pdf| HW4 solns}} | judicious guessing | | | {{:gibson:teaching:spring-2014:math527:hw5.pdf|HW5}} | 03/27 | {{:gibson:teaching:spring-2014:math527:2014-spring-differential-equations-hw-5-solutions.pdf|HW5 solns}} | Laplace transforms | lots of problems, so get started early! | | {{:gibson:teaching:spring-2014:math527:hw6.pdf|HW6}} | 04/03 | {{:gibson:teaching:spring-2014:math527:solutions_of_HW6.pdf|HW6 solns}} | Laplace transforms, s and t translation, delta function | | | {{:gibson:teaching:spring-2014:math527:hw7.pdf|HW7}} | 04/17 | {{:gibson:teaching:spring-2014:math527:solutions_of_HW7.pdf|HW7 solns}} | power series method | | ===== Exams ===== [[:gibson:teaching:spring-2014:math527:policies#exams|Exam policies.]] Exams 1-3 will be held during lecture time, 1:10-2:00pm. ^ ^ ^ ^ ^ ^ | exam 1 | M 2/10 | 1st order eqns | {{:gibson:teaching:spring-2014:math527:exam1-practice.pdf| last year's exam}} and {{:gibson:teaching:spring-2014:math527:exam1-practice-soln.pdf| solutions}} | [[gibson:teaching:spring-2014:math527:exam-results]] | | exam 2 | W 3/5 | 2nd & higher order eqns | {{:gibson:teaching:spring-2014:math527:exam2-practice.pdf| last year's exam}} and {{:gibson:teaching:spring-2013:math527:exam2soln.pdf|solutions}}, and some {{:gibson:teaching:spring-2014:math527:varofparams_problems.pdf| var. of params problems }} and {{:gibson:teaching:spring-2013:math527:hw5soln-corrected.pdf|solutions}} | | | exam 3 | M 4/7 | Laplace transforms | {{:gibson:teaching:spring-2014:math527:exam3sample.pdf| last year's exam }} and {{:gibson:teaching:spring-2014:math527:exam3samplesolns.pdf| solutions}} (there's a sign error in solution to the EC problem)| | final | W 5/14 | everything | | Exam 3 is scheduled for Monday April 7, 1:10-2:00pm.
