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

Explanation

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

### Step 1: Identify the Points
Let point A be \((\cos \theta, \sin \theta)\) and point B be \((\cos \varphi, \sin \varphi)\).

### Step 2: Use the Two-Point Form of the Line Equation
The equation of the line passing through points A and B can be expressed using the two-point form:
\[
