Chapter 14: Q27. (page 767)

Find the amplitude if it exists and period of the function $y = 6 \sin (\frac{2 θ}{3})$ and then graph the function.

Short Answer

Expert verified

The amplitude of $y = 6 \sin (\frac{2 θ}{3})$ is 6.

The period of $y = 6 \sin (\frac{2 θ}{3})$ is $3 π$ .

Step by step solution

Step 1. Write down the given information.

The given function is $y = 6 \sin (\frac{2 θ}{3})$ .

Step 2. Concept used.

A function of the form $y = a \sin (b x) and y = a \cos (b x)$ has amplitude of $|a|$ and period $\frac{360 °}{|b|} or \frac{2 π}{|b|}$ .

Step 3. Evaluating amplitude and period of the given function.

With the help of concept stated above, the amplitude and period of the function is evaluated as:

The amplitude of $y = 6 \sin (\frac{2 θ}{3})$ is $|6| = 6$ .

The period of $y = 6 \sin (\frac{2 θ}{3})$ is $\frac{2 π}{|\frac{2}{3}|} = 3 π$ .

Step 4. Sketch the graph for the function.

The graph for the function $y = 6 \sin (\frac{2 θ}{3})$ is shown below.

Step 5. Conclusion.

The amplitude of $y = 6 \sin (\frac{2 θ}{3})$ is 6.

The period of $y = 6 \sin (\frac{2 θ}{3})$ is $3 π$ .
