$f (t) = \sin (2 t)$

Use the form $a \sin (b x - c) + d$ to find the variables used to find the amplitude, period, phase shift, and vertical shift.

$a = 1$

$b = 2$

$c = 0$

$d = 0$

Find the amplitude $| a |$ .

Amplitude: $1$

Find the period of $\sin (2 x)$ .

The period of the function can be calculated using $\frac{2 π}{| b |}$ .

$\frac{2 π}{| b |}$

Replace $b$ with $2$ in the formula for period.

$\frac{2 π}{| 2 |}$

The absolute value is the distance between a number and zero. The distance between $0$ and $2$ is $2$ .

$\frac{2 π}{2}$

Cancel the common factor of $2$ .

$π$

Find the phase shift using the formula $\frac{c}{b}$ .

The phase shift of the function can be calculated from $\frac{c}{b}$ .

Phase Shift: $\frac{c}{b}$

Replace the values of c $c$ and b $b$ in the equation for phase shift.

Phase Shift: $\frac{0}{2}$

Divide $0$ by $2$ .

Phase Shift: $0$

List the properties of the trigonometric function.

Amplitude: $1$

Period: $π$

Phase Shift: None

Vertical Shift: None

Select a few points to graph.

$\begin{array}{c} x & f (x) \\ 0 & 0 \\ \frac{π}{4} & 1 \\ \frac{π}{2} & 0 \\ \frac{3 π}{4} & - 1 \\ π & 0 \end{array}$

The trig function can be graphed using the amplitude, period, phase shift, vertical shift, and the points.

The height of a cylinder is increasing at a constant rate of 2 meters per second, and the volume is decreasing at a rate of 800 cubic meters per second. At the instant when the radius of the cylinder is 5 meters and the volume is 648 cubic meters, what is the rate of change of the radius? The volume of a cylinder can be found with the equationV=πr2h. Round your answer to three decimal places.
