Find perpendicular distance from the origin of the line joining the points `(costheta,sintheta)`and `(cosphi,sinphi)`.

Explanation

To find the perpendicular distance from the origin to the line joining the points \((\cos\theta, \sin\theta)\) and \((\cos\phi, \sin\phi)\), we can follow these steps:

### Step 1: Write the equation of the line
We will use the two-point form of the equation of a line, which is given by:

\[ y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x - x_1) \]
