  • Unit 3
    • Fixed a broken web link.
August 13, 2020 Update
  • Updates to Homework
    • Posted student generated exemplars of homework write-ups for Units 10-12. We are in the process of having these done for all units and are uploading as we get them. We are replacing "solutions" with these "exemplars."
  • Unit 10
    • Clarified the wording in homework question 8a.
  • Unit 11
    • Clarified the wording in homework question 6.
    • Please note, we still are planning a large overhaul of this unit but that has not happened yet.
August 9, 2020 Update
  • Updates to Homework
    • Posted student generated exemplars of homework write-ups for Units 8-9. We are in the process of having these done for all units and are uploading as we get them. We are replacing "solutions" with these "exemplars."
  • Unit 8
    • Clarified the wording in homework question 1a to align with the exception in 1c.
AUGUST 1, 2020 Update
  • Updates to Homework
    • Posted student generated exemplars of homework write-ups for Units 5-7. We are in the process of having these done for all units and are uploading as we get them. We are replacing "solutions" with these "exemplars."
  • Unit 5
    • Fixed a typo in Homework #6. h(2)=3 was changed to h(12)=8 to make the problem mathematically valid.
July 28, 2020 Update
  • Updates to Homework
    • Posted student generated exemplars of homework write-ups for Units 1-4. We are in the process of having these done for all units and are uploading as we get them. We are replacing "solutions" with these "exemplars."

    • Fixed a few typos
    • One new homework problem (#8)
  • Unit 10
    • Changed b to 2 in problem #7 to connect to changes made in Unit 11
    • Added a GeoGebra 3D applet to help in problem #10a
    • Added a programmable GeoGebra 3D applet to help in problem #14
    • Text was added to HW #8
    • One new homework problem (#9)
  • Unit 11
    • Changes are planned for this unit but they did not get pushed in this update
  • Unit 12
    • One new homework problem (#8)
  • Unit 13
    • New problem was added about repeated roots (#8). This caused the remaining problems to be renumbered.

    • One new homework problem (#10)
  • Unit 14
    • One new homework problem (#6)
  • Unit 15
    • We are in the process of adding a unit on Laplace Transform. The unit is not available yet.
  • Glossary
    • The glossary was split into two, one at the end of first order and one at the end of systems. (Part A and Part B)
    • Every unit how ends with a homework problem encouraging students to go to the glossary and read definitions that are relevant to that unit.
