Psyched about sinusoidals

General – You will be assessed on how well you can graph and interpret  sine and cosine functions tomorrow Quiz 4.1-4.2 (or Tuesday if you are in D-period)

Note:  Assignments 4.1 and 4.2 will be handed in tomorrow

Be sure you :

·         know the meaning of the coefficients of y = a sin b (x –c) + d

·         can determine the period, amplitude, and vertical shift

·         can graph sine an cosine functions using a table of values

3 Key Goals for this week

• Show you know the 4.1 – 4.2 material
• Apply trigonometry functions to real-world situations (sinusoidal relationships – see 4.7)
• Complete more challenging word problems/sample tasks to get ready for next week

 

For those of you who did not complete the New Year's Packet, I have created a second problem set.   You must complete the problems handed to you next class AND the New Year's refresher packet. 

 

For those you who did complete the packet.  You will be given the option of checking another students work once it is completed and/or completing less open-ended problems.

Any extra work completed can be used to raise an earlier homework grade from earlier in the year (the review packets really represent material learned eariler this year).  The new multiple choice problems will be posted on my website under the Ch.4 folder.
