[[:gibson:teaching:fall-2011:math527:exams| Exam results]]

**Exam #3** is scheduled for 8-9am Friday October 28, 2011. The exam room follows the first letter of your last name
  * A-J: McConnell 208
  * K-Z: Hamilton-Smith 127
**Cheat sheet update**: You will be allowed a cheat sheet for the exam, consisting of a table of Laplace transforms written on one side of a 8 1/2 x 11 inch sheet of paper. Only Laplace transforms can be written on the sheet. At the end of the exam, staple your cheat sheet onto your solutions and turn it in.

**Final exam**: As of Oct 25, UNH final exams have not been scheduled. I will post the math 527 final exam schedule as soon as I receive it. 
===== Supplementary material =====

  * [[http://en.wikipedia.org/wiki/Partial_derivative| Partial derivatives]]. A pretty good explanation by wikipedia. The important parts are the [[http://en.wikipedia.org/wiki/Partial_derivative#Introduction|Introduction]], the first third of the [[http://en.wikipedia.org/wiki/Partial_derivative#Basic_definition|Basic Definition]], and the [[http://en.wikipedia.org/wiki/Partial_derivative#Antiderivative_analogue|Antiderivative Analog]]
  * [[http://www.wolframalpha.com|Wolfram Alpha]] and [[http://mathworld.wolfram.com | Wolfram Mathworld]]. Check your homework, deepen your knowledge.
