M3H Day 68 Practice

Front

What is the definition of Period in oscillatory motion?

Back

The horizontal length required to complete one cycle of a wave or oscillation.

Front

What is the amplitude of the function y=-5cos(1/2x+π)?

Back

5

Front

How do you determine the period of the function y = 4Cos(2x)?

Back

The period is calculated as π, derived from the formula T = 2π/B, where B is the coefficient of x.

Front

What is the amplitude of a graph represented by y = 3sin(x)?

Back

3

Front

Identify the function: y=sin(x) or y=cos(x)?

Back

y=cos(x)

Front

What is the general form of a cosine function?

Back

y = A cos(Bx + C) + D, where A is the amplitude, B affects the period, C is the phase shift, and D is the vertical shift.

Front

How does the amplitude affect the graph of a cosine function?

Back

The amplitude determines the height of the peaks and the depth of the troughs of the graph.

Front

What is the relationship between frequency and period?

Back

Frequency is the reciprocal of the period; f = 1/T.

Front

What is the period of the function y = 5sin(3x)?

Back

The period is 2π/3.

Front

What does a negative amplitude indicate in a cosine function?

Back

A negative amplitude reflects the graph across the x-axis.
