Is Point in Domain? Given 2 Real Numbers, Check if They Belong to the Domain

When working with geometric shapes and measurements, it is often necessary to determine whether a certain point belongs to a specific area. In mathematics, this involves analyzing two real numbers and checking if they fall within the boundaries of the given area. This process is crucial in various fields, including computer graphics, image processing, and geographical information systems.

The task of checking whether a point belongs to a given area can be approached in a systematic manner. By defining the boundaries of the area and analyzing the coordinates of the point, it is possible to determine if the point falls within the desired range. This can be achieved through the use of mathematical inequalities and logical operators.

When dealing with two real numbers, the coordinates of the point can be represented as (x, y), where x and y are the respective values on the x-axis and y-axis. By comparing these values to the specified range of the area, it can be determined whether the point falls within or outside the desired region. This process involves considering both the lower and upper limits of the area’s boundaries.

Whether you are working with simple geometric shapes or complex areas, being able to check whether a point belongs to a given area is a fundamental skill. It allows for precise analysis and decision-making based on the location of points within a defined space. By understanding the principles behind this process and utilizing mathematical tools, it is possible to accurately determine if a point is part of a specified area.

Understanding the problem

In the given problem, we need to determine whether a given point belongs to a specified area in a coordinate plane. The area is identified by two real numbers, which represent the range of x and y coordinates within the area.

To solve this problem, we need to define the boundaries of the area. The area can be visualized as a rectangular region on the coordinate plane.

  • The first real number represents the range of x coordinates, with the minimum x value being the lower boundary and the maximum x value being the upper boundary.
  • The second real number represents the range of y coordinates, with the minimum y value being the lower boundary and the maximum y value being the upper boundary.

Given a point with its x and y coordinates, we need to check if the point falls within the specified area or outside of it. If the point satisfies the condition of being within the specified x and y ranges, then it belongs to the area. Otherwise, it does not belong to the area.

Approach to solve the problem

To determine whether a given point belongs to a specified area, we can use a mathematical approach based on the given conditions for the area. In this case, we will be dealing with 2 real numbers representing the coordinates of the point.

First, let’s define the conditions for the specified area. For example, if the area is defined as a rectangle, we will need to know the coordinates of the two opposite corners of the rectangle.

Once we have the conditions for the area, we can proceed to check whether the given point satisfies those conditions. We will compare the coordinates of the point with the boundaries of the area.

For example, if the given point has coordinates (x, y), and the area is defined by the boundaries (x1, y1) and (x2, y2), we can check if the point lies within those boundaries using the following conditions:

ConditionsExplanation
x >= x1The x-coordinate of the point is greater than or equal to the x-coordinate of the left boundary of the area.
x <= x2The x-coordinate of the point is less than or equal to the x-coordinate of the right boundary of the area.
y >= y1The y-coordinate of the point is greater than or equal to the y-coordinate of the bottom boundary of the area.
y <= y2The y-coordinate of the point is less than or equal to the y-coordinate of the top boundary of the area.

If all these conditions are satisfied, then the given point belongs to the specified area. Otherwise, it does not.

By using this approach, we can easily determine whether a given point lies within a specified area based on its coordinates.
