2.6 Cont. Warm-up (IN) 1.Identify the transformations from to 2.Graph Learning Objective: To be able to identify the amplitude, period, 4 sub- intervals, and phase shift before graphing any trig function and to create a trig equation that represents a particular trig graph.
NOTES Amplitude and Period - Amplitude stretches or compresses vertically The period of the sin/cos graphs is found by period # in front of x use the even - odd properties
Ex 1 – Determine the amplitude and period of *~*~ When graphing, use 4 sub-intervals that are governed by the period. In other words, divide the period by 4 to get the desired scale~*~*
Ex sub- intervals
Ex sub- intervals
Ex sub- intervals
Ex 5 - Find an equation that satisfies the graph provided
HW – pg. 187 #37-46,57-65,68,71-73,77-80 Out – Describe how to graph a sin curve. Summary – Today, I think… Don’t forget about POW!!
