7.8 Sinusoidal Graphs

2
**Graph of y = sinx Period = 2𝝅 Amplitude = max – min = 1 – – 1 = 1 2 2**

x y 1 –1 Period = 2𝝅 Amplitude = max – min = 1 – – 1 = 1 2 2

3
**General Sine Curve We’ll do c & d tomorrow**

If a is (+), typical sine curve If a is (–), reflect through x-axis

4
**Ex 1) Graph y = 3sinx b = 1 c = 0 a = 3 d Amp = 3 Period = 2𝝅**

–3 Amp = 3 Period = 2𝝅 Increment length

5
Ex 2) Graph y = sin2x b c a d = 2 = 0 = 1 1 –1 Amp = 1 Per: IL:

6
**Graph of y = cosx Period = 2𝝅 Amplitude = max – min = 1 – – 1 = 1 2 2**

x y 1 –1 Period = 2𝝅 Amplitude = max – min = 1 – – 1 = 1 2 2

7
**General Cosine Curve We’ll do c & d tomorrow**

If a is (+), typical cosine curve If a is (–), reflect through x-axis

8
**Ex 3) Graph b = c = 0 a = –2 d Amp = 2 Per: IL:**

a = –2 reflect across x-axis
