Unit 10 and 11 Review

Front

What is the parent function of the sine function?

Back

f(x) = sin(x)

Front

What is the amplitude of a function defined as f(x) = 3 sin(x)?

Back

The amplitude is 3.

Front

How do you find the measure of an angle using the law of sines?

Back

Use the formula: (a/sin(A)) = (b/sin(B)) = (c/sin(C) ) to find angle A.

Front

What is the parent function of the cosine function?

Back

y = cos(x)

Front

What is the period of the function y = 4 cos(2(x - 1))?

Back

The period is π.

Front

What is the general form of a sine function?

Back

f(x) = a sin(b(x - c)) + d, where a is the amplitude, b affects the period, c is the horizontal shift, and d is the vertical shift.

Front

What is the period of the sine function?

Back

The period of the sine function is 2π.

Front

What is the relationship between the sine and cosine functions?

Back

sin(x) = cos(90° - x) or sin(x) = cos(π/2 - x).

Front

What is the amplitude of the function f(x) = -2 cos(x)?

Back

The amplitude is 2 (amplitude is always positive).

Front

What is the range of the sine function?

Back

The range of the sine function is [-1, 1].
