Introduction

In mathematics, the concept of partitioning a directed segment into a specific ratio is a fundamental idea that has numerous applications in various fields, including geometry, trigonometry, and calculus. In this article, we will delve into the world of directed segments and explore how point P partitions the directed segment from A to B into a 1:3 ratio. We will also examine the concept of point Q, which partitions the directed segment from B to A into a 1:3 ratio.

Understanding Directed Segments

A directed segment is a line segment with a specific direction, represented by an arrow. It is a fundamental concept in geometry and is used to describe the relationship between two points in a plane. In this context, the directed segment from A to B represents a line segment that extends from point A to point B, with the direction from A to B.

Point P Partitions the Directed Segment

Point P partitions the directed segment from A to B into a 1:3 ratio. This means that the distance from A to P is 1 unit, and the distance from P to B is 3 units. In other words, point P divides the directed segment into two parts, with the first part being 1 unit long and the second part being 3 units long.

Mathematical Representation

Mathematically, the directed segment from A to B can be represented as a vector AB, where A is the initial point and B is the terminal point. The vector AB can be written as:

AB = (x2 - x1, y2 - y1)

where (x1, y1) are the coordinates of point A, and (x2, y2) are the coordinates of point B.

Point Q Partitions the Directed Segment

Point Q partitions the directed segment from B to A into a 1:3 ratio. This means that the distance from B to Q is 1 unit, and the distance from Q to A is 3 units. In other words, point Q divides the directed segment into two parts, with the first part being 1 unit long and the second part being 3 units long.

Mathematical Representation

Mathematically, the directed segment from B to A can be represented as a vector BA, where B is the initial point and A is the terminal point. The vector BA can be written as:

BA = (x1 - x2, y1 - y2)

where (x1, y1) are the coordinates of point B, and (x2, y2) are the coordinates of point A.

Relationship Between Point P and Point Q

Point P and point Q are related in that they both partition the directed segment into a 1:3 ratio. However, they do so in opposite directions. Point P partitions the directed segment from A to B, while point Q partitions the directed segment from B to A.

Geometric Interpretation

Geometrically, point P and point Q can be represented as points on a coordinate plane. The directed segment from A to B can be represented as a line segment with a specific direction, while the directed segment from B to A can be represented as a line segment with the opposite direction.

Conclusion

In conclusion, point P partitions the directed segment from A to B into a 1:3 ratio, while point Q partitions the directed segment from B to A into a 1:3 ratio. The relationship between point P and point Q is that they both partition the directed segment into a 1:3 ratio, but in opposite directions. This concept has numerous applications in various fields, including geometry, trigonometry, and calculus.
