Find the general solutions of the following equations: `tan2theta=0` (ii) `tan(theta/2)=0` (iii) `tan(3theta)/(4)=0`

Explanation

To find the general solutions of the given equations, we will solve each equation step by step.

### (i) Solve `tan(2θ) = 0`

1. **Understanding the equation**: We know that the tangent function is zero at integer multiples of π. Thus, we can express this as:
\[ 2θ = nπ \]
