M3U7D5 Warm Up
1. How long does it take to travel three trips around a unit circle?
For 2 & 3, reference the following equation:
y = -3sin(2x)+4
2. What is the maximum value?
3. What is the minimum value?
1080o or 6 7 1

3. U7D5 Graphing Sine and Cosine functions Cont.
OBJ: Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline. F-TF.5

4. Summary: Remember y = d + a sin (bx - c) y = d + a cos (bx - c)
a is the amplitude
period = or
is the horizontal translation
d is the vertical translation

5. REMEMBER…
You must know how to analyze the equation before you can graph it.
The most important thing to remember about graphing is determining the starting point and the stopping point on the t-table.
