Find the length of the perpendicular from the origin to the straight line joining the two points whose coordinates are (a cos α, a sin α) and (a cos β, a sin β).
Given:
Coordinates are (a cos α, a sin α) and (a cos β, a sin β).
To find:
The length of the perpendicular from the origin to the straight line joining the two points whose coordinates are (a cos α, a sin α) and (a cos β, a sin β).
Concept Used:
Distance of a point from a line.
Explanation:
Equation of the line passing through (acosα, asinα) and (acosβ, asinβ) is
The distance of the line from the origin is
Hence, the required distance is
