Step 1. Write down the given information.

The given function is $y = 4 \tan (\frac{θ}{3})$ .

Step 2. Concept used.

A function of the form $y = a \tan (b x) and y = a \cot (b x)$ has undefined amplitude and period $\frac{180 °}{|b|} or \frac{π}{|b|}$ .

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

With the help of concept stated above, the amplitude and period of the function $y = 4 \tan (\frac{θ}{3})$ is evaluated as:

The amplitude of $y = 4 \tan (\frac{θ}{3})$ is undefined.

The period of $y = 4 \tan (\frac{θ}{3})$ is $\frac{π}{|\frac{1}{3}|} = 3 π$ .

Step 4. Sketch the graph for the function.

The graph for the function $y = 4 \tan (\frac{θ}{3})$ is shown below.

Step 5. Conclusion.

The amplitude of $y = 4 \tan (\frac{θ}{3})$ is undefined.

The period of $y = 4 \tan (\frac{θ}{3})$ is $3 π$ .
