===== Notices =====
 
  * **02/07/2014: Please see [[gibson:teaching:spring-2014:math527#Exams]] for exam room assignments.**
  * 02/05/2014: University closed, lecture canceled due to snow. 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.
