For which of these angles is sine negative? Select all that apply.
\(\text-\frac{\pi}{4}\)
\(\text-\frac{\pi}{3}\)
\(\text-\frac{2\pi}{3}\)
\(\text-\frac{4\pi}{3}\)
\(\text-\frac{11\pi}{6}\)
The clock reads 3:00 p.m.
Which of the following are true? Select all that apply.
In the next hour, the minute hand moves through an angle of \(2\pi\) radians.
In the next 5 minutes, the minute hand will move through an angle of \(\text-\frac{\pi}{6}\) radian.
After the minute hand moves through an angle of \(\text-\pi\) radians, it is 3:30 p.m.
When the hour hand moves through an angle of \(\text-\frac{\pi}{6}\) radian, it is 4:00 p.m.
The angle the minute hand moves through is 12 times the angle the hour hand moves through.
Plot each point on the unit circle.
Which of these statements are true about the function \(f\) given by \(f(\theta) = \sin(\theta)\)? Select all that apply.
The graph of \(f\) meets the \(\theta\)-axis at \(0, \pm \pi, \pm 2\pi, \pm 3\pi, \ldots\)
The value of \(f\) always stays the same when \(\pi\) radians are added to the input.
The value of \(f\) always stays the same when \(2\pi\) radians are added to the input.
The value of \(f\) always stays the same when \(\text-2\pi\) radians are added to the input.
The graph of \(f\) has a maximum when \(\theta = \frac{5\pi}{2}\) radians.
Here is a unit circle with a point, \(P\), at \((1,0)\).
For each listed positive angle of rotation of the unit circle around its center, indicate on the unit circle where \(P\) is taken, and give a negative angle of rotation that takes \(P\) to the same location.
In which quadrant are both sine and tangent negative?
Quadrant I
Quadrant II
Quadrant III
Quadrant IV
Technology required. Each equation defines a function. Graph each of them to identify which are periodic. Select all that are.
\(y = \sin(\theta)\)
\(y = e^x\)
\(y = x^2 - 2x + 5\)
\(y = \cos(\theta)\)
\(y = 3\)
