Wednesday 17 May class (updated)

UPDATE: I have posted the remaining problems from the Proving Trigonometric Identities worksheet over on Piazza. You may submit a student solution for a homework point to any one of these (if it has not already got a student solution). Please follow these instructions: Either type in your solution using good Math notation as described in this post, or else write up your work NEATLY and take a CLEAR and LEGIBLE photo and post it as the student solution. Illegible solutions or solutions which do not use the method in the worksheet will be deleted and receive no credit. (You should put a bit of effort into this!)

——————————————————

(after Test 4)

Topics:

• Logarithms and exponents
• Finding exact values of logarithms
• Properties of logarithms

Here are the resources that I use in class:

Definition of logarithms (Math is Fun) – this goes all the way back to the very basics.

Introduction to logarithms (Math is Fun)

For next time: Working with exponents and logarithms (Math is Fun)  – you only read down to where it says “The Natural Logarithm and Natural Exponential Function”

Those sources from Math is Fun contain just about everything you need to know about logarithms and using them, so far!

My slideshow about logarithms: (I’m still working on this and I may upload a more extensive version, so check back!)

The Precalculus textbook (we use some examples from here, Session 13, Example 13.9 on p. 191.)

Homework:

• Right about now would be a good time to review my Course Policies especially as they relate to grading.
• Review the examples discussed in class. Make use of the resources linked above: they are focused on exactly what we need to work on!
• Do the following problems: (They are from the Precalculus textbook linked above: you can check your answers by looking into the answer sections there)

• Also find the exact value of these without using a calculator:
  1. 
  2. 
• Do the WeBWorK: due by Sunday 11 PM, but start early and try to do distributed practice!

NOTE: You may put any of the above homework problems on the board at the start of class next time. Please do NOT put the Final Exam Review problems on the board until I call for them! We will have to do one more very short topic before that, which is solving simple exponential equations using logarithms. It will be helpful if you read ahead:

For next time: logarithm practice worksheet: basic skills 8 logarithms

Here is the updated Final Exam Review sheet (the one on the Math Department website has NOT been updated): we will have to provide solutions to problem 10 in our method.

Remember that you can use the Piazza discussion board to ask questions if you get stuck on any of the WeBWorK or the other homework problems. Don’t forget to include the problem itself in your question, as that will make it easier for you to get a quick response!
