  1. Homework Pg. 359 - 1(a,c,d), 2, 3a, 4(a, d), 5, 8 Resources Quantitative Environmental Learning Project http://www.seattlecentral.edu/qelp/sets/078/078.html

  2. Focus time • No talking • No eye contact

  3. CO2 and Climate Change Periodic Functions Unit (Chp.5)

  4. Video

  5. Do you think we’ll save ourselves in time?

  6. Sin(x)

  7. Periodic Function A pattern of y-values that repeats at regular intervals

  8. Is this function periodic? NO! The y-values change over time

  9. Period The time it takes to complete a pattern

  10. period

  11. What’s the period of this function?

  12. What’s the period of this function?

  13. What’s the period of this function?

  14. ? What’s the period of this function? The period of this function is 2π

  15. Amplitude (A) From the middle of the graph to the peak

  16. A Method 1 Count from middle to peak A = 3 ppm

  17. max to min Method 2 Find max to min, then divide by 2 Max-to-min = 6 A = 6/2 = 3

  18. max to min What is the amplitude?

  19. 3 0.5 What is the amplitude?

  20. What is the amplitude? 3.5

  21. What is the amplitude? A = 1.75

  22. If f(1964) = 322.00 and the period of the function is 1 year, what is f(1965) = ?

  23. If f(1964) = 322.00 and the period of the function is 1 year, what is f(1965) = ? Since the pattern repeats exactly 1 year later, the level of carbon dioxide will be the same

  24. If f(3) = 3 and f(6) = 2 and the period for the function is 8 what is f(11) = ?

  25. Period = 8 If f(3) = 3 and f(6) = 2 and the period for the function is 8 what is f(11) = ?
