Hey everyone,
My period 1 class has its exam tomorrow (Friday) at 9:00am in our regular classroom (260). You can ask me questions tonight if you like, and I’ll do my best to be at school around 8:00am tomorrow.
If you do send me a specific question, it’s helpful if you include a picture of your work for me to refer to.
You can get me on Twitter (@bgrasley), by email, or by commenting on this post!
Here’s the trig summary I handed out in class:
We’re done with new concepts in the course! Now we practice our skills.
Here’s today’s work:
Page 402 #9, 10, 12
Page 410 #8, 9, 13
Page 419 #8, 9, 11
Page 428 #5,9
Here’s a quick self-check “quiz”:
For even more practice, you can try pages 430-433.
Here’s the promised video – sorry for the weird zooming, but I didn’t want to record it again :)
Hey everyone,
We learned the Cosine Law today. Turns out I don’t already have a video explaining how the Cosine Law works, so I’ll put one together for you this evening. Feel free to browse the web for another, though.
Homework this evening is Page 409 #4 and Page 418 #5. For more Sine Law practice try Page 402 #5.
We learned the Sine Law today!
Complete Page 402 #6 for homework. I meant to assign #5 also, but I forgot. Feel free to complete it too :)
Page 362 #5-8
Page 373 #8-12
Just do some of them – LOTs of questions here!
We’ve been using the primary trig ratios to solve triangles. Here’s the sheet I gave you today (we haven’t completed the third page yet):

Welcome back!
Today we started our Trigonometry unit. We reviewed the terms similar and congruent as they applied to shapes like triangles, then we learned how to use the side-length ratios to find missing sides given congruent shapes.
Your homework is to complete Page 348 #6ace, 7, and 11.
For anyone who has a test or assignment to complete for me I’ll be in my room every day at lunch time.
Here’s today’s review:
