TRIGONOMETRY, 4.0: STUDENTS GRAPH FUNCTIONS OF THE FORM F(T)=ASIN(BT+C) OR F(T)=ACOS(BT+C) AND INTERPRET A, B, AND C IN TERMS OF AMPLITUDE, FREQUENCY, PERIOD, AND PHASE SHIFT. Graphing Sine and Cosine Functions

2
Objectives Key words 1. Graph the equations of sine and cosine functions given the amplitude, period, phase shift, and vertical translation 2. Write equations given a graph. 3. Graph compound functions Midline Amplitude Maximum Minimum Period Sine curve Cosine curve Phase shift Graphing Sine and Cosine Functions

3
Quick check! Can you find the distance between two numbers? Can you find the midpoint between two numbers?

4
Order does matter! y=A sin[B(θ-h)]+k y=A cos[B(θ-h)]+k y=A sin[B(θ-h)]+k y=A cos[B(θ-h)]+k 1: Graphing Sine and Cosine Functions

5
State the amplitude, period, phase shift, and vertical shift for y = 4cos(x / 2 + π) - 6. Then graph the function.
