Trig Waves

The highest point on a wave is:

• the crest
• the trough
• the top
• the coast 

What property of the wave is represented by the letter "B"?

• amplitude
• frequency

• period

• midline

What is the period of

y=cos(3x) - 5?

• π/3

• π/6

• 2π/3

• 2π/6

Where are the lowest and highest points of
y= -3sin(x)-2?

• [-2,2]
• [-5,1]
• [-4,2]
• [-3,3]

• A
• B
• C
• D

y = -4 cos (5x) + 2 has a frequency of

• 4

• 5

• 2

• -4

y = -4 cos (5x) + 2 has a midline of

• y = 2

• y = 5

• y = -4

• y = 0

Starting from the y-axis, y = -4 cos (5x) + 2 will have one have wave completed by the time it reaches

y = -4 cos (5x) + 2 shifted left π radians would have an equation of

• y = -4 cos (5x - π) + 2

• y = -4 cos (5x + π) + 2

• y = -4 cos (5x) + 2 - π

• y = -4 cos (5x) + π
