| HW6 | Tue 03/03 | hw6solns.pdf | nonhomogeneous equations: judicious guessing | |
| HW7 | Tue 03/10 | hw7solns.pdfaddendum | variation of parameters | For problem 4, don't solve the initial value problem. Just find the general solution. Use tables of integrals! |
| HW8 | Tue 03/31 | hw8solns.pdf | power series, Laplace transforms | |
| HW9 | Tue 04/07 | hw9solns.pdf | Laplace transforms, s & t translation | |
| – | Tue 04/14 | canceling this HW, instead here are some practice problems for exam #3 from last year's HW. You can find solutions here and here | ||
| HW10 | Thu 04/23 | hw10solns.pdfhw10addendum.pdf | linear algebra | don't turn in problems 7-11 – most of these will be incorporated into HW11 |
| HW11 | Thu 04/30 | hw11solns.pdf | systems of ODEs | fixed typo in problem 1; for complex eigenvalues, express answer in both complex and real-valued forms |
The final exam is Tuesday, May 12 10:30-12:30pm. The exam will be split into three rooms:
In Spaulding 120, please sit in alternating seats inwards starting from the middle aisle. In Spaulding G70, please follow the teaching assistant's instructions for double-spaced seating.
