Answer

Explanation:

Step1: Recall the value of cotangent

We know that (\cot\theta=\frac{\sqrt{3}}{3}) when (\theta = \frac{\pi}{3}+n\pi), (n\in\mathbb{Z}). So for (\cot(3x)=\frac{\sqrt{3}}{3}), we have (3x=\frac{\pi}{3}+n\pi).

Step2: Solve for (x)

Divide both sides of (3x=\frac{\pi}{3}+n\pi) by (3). Then (x = \frac{\pi}{9}+\frac{n\pi}{3}).

Step3: Find solutions in the interval ([0,2\pi))

When (n = 0), (x=\frac{\pi}{9}). When (n = 1), (x=\frac{\pi}{9}+\frac{\pi}{3}=\frac{4\pi}{9}). When (n = 2), (x=\frac{\pi}{9}+\frac{2\pi}{3}=\frac{7\pi}{9}).

When (n = 3), (x=\frac{\pi}{9}+\pi=\frac{10\pi}{9}). When (n = 4 ), (x=\frac{\pi}{9}+\frac{4\pi}{3}=\frac{13\pi}{9}). When (n = 5), (x=\frac{\pi}{9}+\frac{5\pi}{3}=\frac{16\pi}{9}).

Answer:

(x=\frac{\pi}{9},\frac{4\pi}{9},\frac{7\pi}{9},\frac{10\pi}{9},\frac{13\pi}{9},\frac{16\pi}{9})
