Practice problems will be posted shortly. * 02/09/2015: Exam #1 will take place as scheduled on Wed. 02/11/2015. Please see the [[gibson:teaching:spring-2015:math527#exams|Exams]] section below for exam room assignments and other important information. * 01/26/2015 IMPENDING BLIZZARD: It is likely that classes will be canceled tomorrow due to snow. In that case, homework will be due in recitation sections Thursday 01/29/2015. * 01/21/2015: Add/drop forms for this course, including changes in recitation sections, are approved and signed by the Math Dept office, W383 Kingsbury Hall. The instructor and TAs cannot sign these forms. * 01/20/2015: You are responsible for reading and understanding the course [[gibson:teaching:spring-2015:math527:policies]] and [[gibson:teaching:spring-2015:math527:syllabus]]. ---- ===== Homework ===== [[:gibson:teaching:spring-2014:math527:policies#homework|Homework policies.]] Homeworks are due in recitations on Tuesdays, with the exception of HW11 and HW12, which are due on Thursdays. ^ homework ^ due ^ solutions ^ topic ^ notes ^ | {{:gibson:teaching:spring-2015:math527:hw1.pdf|HW1}} | Tue 01/27 |{{:gibson:teaching:spring-2015:math527:hw1solns.pdf|}} | separation of variables | some solutions are implicit | | {{:gibson:teaching:spring-2015:math527:hw2.pdf|HW2}} | Tue 02/03 |{{:gibson:teaching:spring-2015:math527:hw2solns.pdf|}}| 1st order linear | | | {{:gibson:teaching:spring-2015:math527:hw3.pdf|HW3 }} | Tue 02/10 | {{:gibson:teaching:spring-2015:math527:math527hw3solns.pdf|hw3solns.pdf}}| exact equations | | | {{:gibson:teaching:spring-2015:math527:hw4.pdf|HW4 }} | Tue 02/17 |{{:gibson:teaching:spring-2015:math527:math527hw4solns_-_feb_18_2015_9-33_am.pdf|hw4solns.pdf}} | applications of 1st order ODEs | | | {{:gibson:teaching:spring-2015:math527:hw5.pdf|HW5 }} | Tue 02/24 |{{:gibson:teaching:spring-2015:math527:hw5solns.pdf|}} | 2nd order linear homogeneous | | | {{:gibson:teaching:spring-2015:math527:hw6.pdf|HW6}} | Tue 03/03 |{{:gibson:teaching:spring-2015:math527:hw6solns.pdf|}} | nonhomogeneous equations: judicious guessing | | | {{:gibson:teaching:spring-2015:math527:hw7.pdf|HW7}} | Tue 03/10 |{{:gibson:teaching:spring-2015:math527:hw7solns.pdf|}}{{:gibson:teaching:spring-2015:math527:prob5partd_addendum.pdf|addendum}} | variation of parameters | For problem 4, don't solve the initial value problem.
