Sine, Cosine, and Tangent Graphs

Front

What is the amplitude of a sine or cosine graph?

Back

The amplitude is the maximum distance from the midline of the graph to its peak or trough. It is half the distance between the maximum and minimum values of the function.

What is the period of a sine or cosine function?

Back

The period is the horizontal length required to complete one full cycle of the graph. For sine and cosine functions, the period is typically 2π.

Front

How do you determine the period of a sine or cosine function from its equation?

Back

The period can be determined from the coefficient of x in the function's equation. For y = a sin(bx), the period is given by 2π/|b|.

What is the period of the function y = sin(2x)?

Back

The period is π, since b = 2 in the equation y = sin(bx).

What is the tangent function's period?

Back

The period of the tangent function is π.

Front

Which of the following functions has a period of 2π: y = sin(x), y = cos(x), or y = tan(x)?

Back

Both y = sin(x) and y = cos(x) have a period of 2π, while y = tan(x) has a period of π.

What is the phase shift in a trigonometric function?

Back

The phase shift is the horizontal shift left or right for periodic functions, determined by the value of c in the equation y = a sin(b(x - c)).
