Plot the poitns whose coordinate are given below.
(i) `(2,3pi)`
(ii) `(2,-2pi//3)`
(iii) `(-3,3pi//4)`.

Explanation

To plot the points given in polar coordinates, we will convert each point into Cartesian coordinates and then plot them on the Cartesian plane. The polar coordinates are given as (r, θ), where r is the distance from the origin and θ is the angle measured from the positive x-axis.

### Step-by-Step Solution:

1. **Convert the first point (2, 3π) to Cartesian coordinates:**
- The polar coordinates are (r, θ) = (2, 3π).
- Convert to Cartesian using the formulas:
- \( x = r \cdot \cos(θ) \)
