Back

70°

Front

What is the formula to find the period of a sine or cosine graph?

Back

The period is given by \( \frac{2\pi}{B} \).

Front

Write the equation for a sine function with a reflection over the x-axis, period of \( \pi \), a phase shift of right \( \frac{\pi}{2} \), and a vertical shift of 4.

Back

\( y=-\sin(2x-\pi)+4 \)

Front

Which equation represents a cosine function reflected over the x-axis?

Back

\( y= -\cos(2x) \)

Front

What is the relationship between degrees and radians?

Back

180° is equivalent to π radians.

Front

How do you convert radians to degrees?

Back

Multiply the radian measure by \( \frac{180}{\pi} \).

Front

How do you convert degrees to radians?

Back

Multiply the degree measure by \( \frac{\pi}{180} \).

Front

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

Back

The amplitude is 3.

Front

What is the phase shift of the function \( y = \sin(x - \frac{\pi}{3}) \)?

Back

The phase shift is \( \frac{\pi}{3} \) to the right.
