FourFive Addition to Trigonometry Playlist
It still doesn't feel like spring! In response to a student request to add FourFive Seconds to the Trig. playlist, consider it added. However, I originally thought I heard "Forty-Five" which connected to 45 seconds per minute loosely relating the lyrics to Trig. Forty-Five clock seconds representing 3pi/2 radians of a turn of course. But since Paul McCartney is involved we can add it to the playlist.
Two of Three
If I had to choose one number theme to relate FourFive to what we learned last week to what we will learn this week it is two of three. In simplest terms, if you can identify Two of Three math facts in a word problem, you typically can connect to the elationship (Formula) you need to apply.
Typical Problems from Last Week:
Know: Angle in Radians and Radius Want: Arc Length
Know: Rotations and Time Want: Angular Speed
Know: Angular Speed and Radius Want: Linear Velocity
Two of Three Examples you will see this week:
Given a Triangle:
Know: An OPPOSITE and HYPOTENUSE
Want: The SINE of the Angle
SOH CAH TOA. There is even a two of three mnemonic
to help you make decisions for basic trigonometry.
Note: SOH CAH TOA should be familiar from previous classes. If it is not, I strongly recommend you visit Khan Academy (or another site) for basic trigonometry review. https://www.khanacademy.org/math/trigonometry/basic-trigonometry view first video and example.

"So What'cha Want" to inspire you to show your work

"My Shirona" because it sounds like the mnemonic SOH CAH TOA

"The Logical Song" because you need to know radical form

and because classic music videos are a lost art form.

What Time is it! Time for My Three Songs.
Happy Spring!
Before Pandora, Spotify, and itunes, some radio stations used to play “My
Three Songs” and listeners had to guess what they had in common. These three songs have circles in
common! Here are your three Trig. Songs for
the week and 6 extra credit opportunities.
Note: You may respond for extra credit
one time and be the
first commenter/not duplicate someone else’s response to earn credit (read
blog comments section before responding).
To clarify who you are and get credit, write your response in the comments section.
e.g. The Artist is Sade! and note that is sounds like “Gaudet” - grs
Note the 6.1d has not been assigned as of Sunday and
E-Period has not received the ASMT2 Handouts yet.
It has been a while since we made musical connections to our class
content
(see Missy Elliot in February or of Course Sade’s Smooth Operator in
Quarter2).To clarify who you are and get credit, write your response in the comments section.

This is unconventional way to earn credit, but the time is now Spring
and we have to mix things up. Plus, we
need more two-way communication and this is one way to implement a blog. Also, recall that I did ask you to follow
this blog earlier in the year. I may
reward the followers. My Seniors, hang
in there we are not done yet.
I created a google document that will be updated as new material is
assigned. The document can be view here:
