Question

बिन्दु P(x, y) की मूल बिन्दु से दूरी क्या होगी :​

Answer 1

Rule:

If two points A and B be taken with coordinates (x₁, y₁) and (x₂, y₂), then the distance between them be measured as

|AB| = √{(x₁ - x₂)² + (y₁ - y₂)²} units

Solution:

The two points are P (x, y) and the origin O (0, 0). Thus the distance between them is

|OP| = √{(x - 0)² + (y - 0)²} units

= √(x² + y²) units
