Webwork update

There are four more Webwork sets to complete this semester. All four are due Monday night at 11:59pm.

  • LogarithmicProperties
  • CompoundInterest
  • ExponentialEquations
  • ExponentialEquations-Calc

All old Webwork sets have been reopened; if you would like to continue to work on them to improve your Webwork grade, you have until Tuesday morning at 12:00am (this is really Monday night, one minute after the four sets above are due).



  • TrigEquations due Monday
  • LawOfSines & LawOfCosines due Wednesday

Test #3 will be given in class next Thursday, December 7. It will cover all of the trigonometry topics from session 18-25

Here‘s a link to the trigonometric equations worksheet from today’s class.


  • Next Tuesday follows a Friday schedule, so I won’t see you then.
  • Next Thursday is Thanksgiving, so I won’t see you then.
  • Webwork GraphingSineCosine due 11/27
  • The next time I see you is 11/28
  • Your next quiz will be on 11/30 on sections 4.1/4.2/1.4/5.1 (probably 4.1/4.2)
  • We’re about half-way through sections 1.4/5.1 (Trigonometric Identites). There is no Webwork set associated with this lesson. We’ll go over a few examples after the break but you can get a jump by looking at the homework from the text and #10 on the final exam review sheet.
  • Today was session 23. The final exam is session 30 (December 19). Now is a good time to start reviewing material that has already been covered to prepare for the final exam. There’ll be less time after the break and before the final exam than you might think!
  • Happy Thanksgiving!
