Solve Cotangent
1. The problem is to solve the equation $2\cot 2x = 3$ for $x$.
2. Start by isolating the cotangent term: $$\cot 2x = \frac{3}{2}$$
3. Recall that $\cot \theta = \frac{\cos \theta}{\sin \theta}$, but here it's easier to solve by rewriting in terms of tangent since $\cot \theta = \frac{1}{\tan \theta}$.
4. So, $$\tan 2x = \frac{2}{3}$$
5. Now solve for $2x$: $$2x = \arctan\left(\frac{2}{3}\right) + k\pi, \quad k \in \mathbb{Z}$$ because tangent has period $\pi$.
6. Divide both sides by 2 to get $x$: $$x = \frac{1}{2} \arctan\left(\frac{2}{3}\right) + \frac{k\pi}{2}, \quad k \in \mathbb{Z}$$
7. This is the general solution for $x$.
Final answer:
$$x = \frac{1}{2} \arctan\left(\frac{2}{3}\right) + \frac{k\pi}{2}, \quad k \in \mathbb{Z}$$
