The text provides a formula for calculating the distance between two points in polar coordinates. The formula is:

\[ d = \sqrt{r_1^2 + r_2^2 - 2r_1r_2 \cos(\theta_1 - \theta_2)} \]

This formula is used to find the distance between the two points given in polar coordinates:

- Point 1: (3, π/6)
- Point 2: (2, π/3)

To apply the formula, substitute the values for \( r_1 = 3 \), \( r_2 = 2 \), \( \theta_1 = \pi/6 \), and \( \theta_2 = \pi/3 \) into the equation.
