How do you graph #r=2sin3theta#?

Start with
Explanation:
First it's good to remember the basic graph of
graph{sinx [-6.25, 6.25, -2.2, 2.2]}
The graph spans
Now let's make the needed adjustments.
First there's the 2. It is going to take the result of the sin function and increase it by a factor of 2. So the maximum and minimum on the y-axis will go from 1 to 2. That will look like this:
graph{2sinx [-6.25, 6.25, -2.2, 2.2]}
And now the
graph{sin(3x) [-6.25, 6.25, -2.2, 2.2]}
Put it all together and we get:
graph{2sin(3x) [-6.25, 6.25, -2.2, 2.2]}
