Front

What does a correlation coefficient of r = -0.89 indicate?

Back

Strong negative correlation

Front

What is the exact value for \( \sin(-135^{\circ}) \)?

Back

\( -\frac{\sqrt{2}}{2} \)

Front

Define Amplitude in the context of sine and cosine functions.

Back

Amplitude is the maximum distance from the midline to the peak (or trough) of the graph.

Front

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

Back

The period is \( \frac{2\pi}{2} = \pi \).

Front

How do you find the maximum value of the function y = 2sin(x) - 2?

Back

The maximum value is 2 - 2 = 0.

Front

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

Back

The frequency is \( \frac{1}{2\pi} \).

Front

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

Back

The range is [-3, 3].
