Introduction

In mathematics, the distance between two points in a 2D plane is a fundamental concept that has numerous applications in various fields, including physics, engineering, and computer science. The distance between two points can be calculated using the Euclidean distance formula, which is a straightforward and efficient method for determining the distance between two points in a 2D plane.

What is Euclidean Distance?

The Euclidean distance, also known as the straight-line distance, is the shortest distance between two points in a 2D plane. It is calculated using the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the lengths of the other two sides.

Calculating Euclidean Distance

The Euclidean distance between two points (x1,y1){(x_1, y_1)} and (x2,y2){(x_2, y_2)} can be calculated using the following formula:

d=(x2−x1)2+(y2−y1)2{d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}}

where d{d} is the Euclidean distance between the two points.

Example: Find the Distance Between Two Points

Let's consider two points in a 2D plane: (−19,−11.8){(-19, -11.8)} and (10,−11.8){(10, -11.8)}. We want to find the distance between these two points using the Euclidean distance formula.

Step 1: Identify the Coordinates

The coordinates of the two points are:

  • Point 1: (−19,−11.8){(-19, -11.8)}
  • Point 2: (10,−11.8){(10, -11.8)}

Step 2: Apply the Euclidean Distance Formula

Now, we can apply the Euclidean distance formula to calculate the distance between the two points:

d=(10−(−19))2+(−11.8−(−11.8))2{d = \sqrt{(10 - (-19))^2 + (-11.8 - (-11.8))^2}}

d=(10+19)2+(−11.8+11.8)2{d = \sqrt{(10 + 19)^2 + (-11.8 + 11.8)^2}}

d=(29)2+(0)2{d = \sqrt{(29)^2 + (0)^2}}

d=841+0{d = \sqrt{841 + 0}}

d=841{d = \sqrt{841}}

d=29{d = 29}

Step 3: Interpret the Result

The result of the calculation is d=29{d = 29}, which means that the distance between the two points (−19,−11.8){(-19, -11.8)} and (10,−11.8){(10, -11.8)} is 29 units.

Conclusion

In conclusion, the Euclidean distance formula is a simple and efficient method for calculating the distance between two points in a 2D plane. By applying the formula, we can easily determine the distance between two points, which has numerous applications in various fields.
