Front

What is the range of the function y = -3sin(x) - 2?

Back

The range is [-5, 1].

Front

What is the period of the sine function represented by y = -3sin(x) - 2?

Back

The period is π.

Front

What is a coterminal angle?

Back

Coterminal angles are angles that share the same terminal side when drawn in standard position. For example, 832° is coterminal with 72°.

Front

How do you set up a trigonometric equation for a given angle?

Back

For an angle of 47°, the correct setup is cos(47) = 28/x.

Front

What is a reference angle?

Back

A reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For 47°, the reference angle is 43°.

Front

What is the amplitude of the function y = -3sin(x) - 2?

Back

The amplitude is 3.

Front

How do you find the amplitude of a sine function?

Back

The amplitude is the absolute value of the coefficient in front of the sine function.

Front

What is the formula for finding the period of a sine function?

Back

The period is given by the formula: Period = 2π / |b|, where b is the coefficient of x.

Front

What is the significance of the negative sign in y = -3sin(x) - 2?

Back

The negative sign indicates a reflection over the x-axis.

Front

How do you convert degrees to radians?

Back

To convert degrees to radians, multiply by π/180.
