Parent Teacher Interviews

I'd just like to take a moment to thank the parents who came in last night to see me. It's nice to be able to discuss your childrens' progress and get feedback on how things are going. It's unfortunate that I'm unable to be at the school today, but I'd like to let everyone know that you don't have to wait for parent teacher interviews to discuss your children's progress. If you like you can always e-mail me, or call the school (328-5364).

It was nice to hear that some of you are checking the blog from time to time to catch up on notes, examples, or the day's assignments. That was good to know and has motivated me to post more frequently. If you do happen to 'drop by,' leave a quick comment if you could to let me know if what I posted was helpful or not. That way I'll know what is helpful, or what I can do to improve. After all, we're never too old or experienced to learn something new.

Thanks again, stay in touch, and good luck in the second half of our semester.

More Physics Homework

Today's Homework discussion

Some mental math...

With an eye on the upcomming weekend

Physics 12

• Today we discussed the conservation of energy again, but this time trying to better understand the new 'super-formulas' we have been given to work with.



• The key to working with these is to make sure you understand not just how to use them but when...



• I hope you will make time to complete some questions numbered 94 and up as I'm planning a quiz for tomorrow on section 9.9.

Trans Math 9

• Today we looked at how to write very large and very small numbers using scientific notation. We even looked at an example of how to use the exponent rules we've been using to help us with calculations we might see in Physics or Chemistry courses.

Pre-Calc 10

• In class today we did an example from lesson 3 using regular trig (SOH CAH TOA), and the sine law. Then we did the same question using the Law of Cosines and noticed how much easier it is.


• We looked at the links in a previous post for calculating values using the law of cosines and a page with a detailed summary of the two laws with some practice questions. Tomorrow I expect that we'll use our time to discuss any difficulties you may be having with the Law of Cosines and we'll write our Module 4 test on Monday the 26th.

Physics 11: Chapter 8 Test.

• It was good to see so many students in to get some last minute advice today. Remember that you don't have to wait for the day of a test to come and see me about your work. Hope it went well for you.


• Tomorrow we'll be moving into a new topic.

The Law of Cosines...A few points to remember

The above link will take you to a site for practice with the law of cosines. I suggest trying it out with a few questions from your assignment first as a check to see how you're making out with your calculator. This formula can be difficult to work with at first. Then make up a few triangles of your own that require the use of the law of cosines and use the applet to find your answers. This particular topic can require a fair bit of practice, so make up some questions of your own to try.



This link will take you to a page that covers the two Trig laws we've covered so far and explains them in quite a bit of detail. The explanations are followed by some problems that you could try. I suggest drawing the triangles described (an important skill to learn), then try answering them. There are answers at the bottom of the page so that you can check your work.



Happy solving!

The day's events.

• Pre-Calc; we reviewed previously assigned questions today in preparation for a quiz on lesson 3 today. Be sure to look over the examples in lesson 3
• Physics 11: we reviewed sane of the questions from the end of the chapter in preparation of ow chapter 8 test tomorrow.
