Half Closed Interval Notation
Since we denote an open interval by and a closed interval by , we denote a half-closed interval by a mixture of those two notations. Imagine your interval has endpoints a and b:
- If a is included and b isnt, we can say the interval is [a,b).
- If b is included and a isnt, we write it as (a,b].
It looks like mismatched brackets, but its really just a clever way of denoting which side is in the interval and which side isnt.
Theres one more way of denoting open intervals which you may not have come across yet: with backward square brackets. Using that notation, your half closed intervals become a,b].
Here we use mathematical set notation to define these phrases:
Definition Of A Segment
A segment is a set of points consisting of two points of the line called the endpoints, and all of the points of the line between the endpoints. It is commonly used to represent the length, height, or width of a certain object and the distance between two objects. It is named by using the label of its endpoints and insert a line ) above the letters. Figure 2 shows segment AB which can also be written as .
Draw two points and label it as C and D.
Connect the two points straight each other.

What Is An Endpoint
An endpoint is a remote computing device that communicates back and forth with a network to which it is connected. Examples of endpoints include:
- Internet-of-things devices
Endpoints represent key vulnerable points of entry for cybercriminals. Endpoints are where attackers execute code and exploit vulnerabilities, as well as where there are assets to be encrypted, exfiltrated or leveraged. With organizational workforces becoming more mobile and users connecting to internal resources from off-premises endpoints all over the world, endpoints are increasingly susceptible to cyberattacks. Objectives for targeting endpoints include, but are not limited to:
- Use an endpoint as an entry and exit point to access high-value assets and information on an organizations network.
- Access assets on the endpoint to exfiltrate or hold hostage, either for ransom or purely for disruption.
- Take control of the device and use it in a botnet to execute a DoS attack.
Endpoint Security Strategies
For decades, organizations have heavily relied on antivirus as a means to secure endpoints. However, traditional antivirus can no longer protect against todays sophisticated threats.
The most powerful and comprehensive endpoint security solutions can gather and correlate all of this data centrally in addition to performing local analysis on individual endpoints.
Example: Using The Endpoint Calculator
Say that four months ago, you began posting videos on YouTube. Nothing fancy, just a few cooking recipes that are traditional to your region. It started as a hobby, but people seem to be enjoying the show and you see the number of viewers increasing linearly with time. Why don’t we try to find the missing endpoint with our calculator to check how many there should be in four month’s time?
First of all, note that although the problem doesn’t seem geometrical at all, we can indeed find the answer using the endpoint definition from geometry. After all, the starting point, i.e., month zero, was when you began posting the videos, so we were at 0 viewers at that point. Now, we’re at month four, which will be our midpoint . In other words, the endpoint will be our answer.
Say that currently, you have54,000, and let’s try to translate all this data in such a way that the endpoint calculator will understand what we want from it.
According to the above section, in order to find the answer, we need the starting point and the midpoint. Let’s denote them by A = and M = , respectively. For us, the x’s will denote the number of months in we are, and y’s will be the number of viewers. Since our starting point was month zero, and we’re currently 4 months in, we have
xâ = 0,
x = 4.
Now it’s time for the subscribers. Again, the starting point was when we had no one, while right now, after the four months, we’re at 54,000. Therefore, we have
yâ = 0,
y = 54,000.
xâ = 2*4 – 0 = 8,
What Is An Endpoint And Do You Need An Endpoint Data Protection Solution
Jargon abounds in the technical world of IT, with obscure-but-precise language sometimes getting in the way of conceptual understanding. The term endpoint fits the bill. While it may make sense to a seasoned IT professional, the rest of us may need a little help. What exactly is an endpoint, why does it matter, and do you need an endpoint backup solution?
According to Wikipedia, Endpoint is a hardcore punk band from Louisville, Kentucky. A more common definition for endpoint in computer networking, architecture, and operations, however, is a mobile device such as a laptop, phone, or tablet.
The term has its origin in reference to computer networks. The endpoint is a device or node that connects to the LAN or WAN and accepts communications back and forth across the network. In a traditional sense, an endpoint can be a modem, hub, bridge, or switch. It also could be data terminal equipment or a host computer .
Yet today, endpoint is used most commonly in network security and end-user mobility circles to mean any device outside the corporate firewall. This could be laptops, tablets, or mobile phones on the edge of the network, which individuals connect to the central network.
What Does A Closed Dot Mean In Math
closeddot meansdot meansdotsmeans
1) Draw a number line. 2) Put either an open circle or a closed dot above the number given. For and , use a closed dot to indicate the number itself is part of the solution. For < and >, use an open circle to indicate the number itself is not part of the solution.
One may also ask, what do open and closed circles mean in limits? An open circle represents a hole in a function, which is one specific value of x that does not have a value of f. With limits, the limit exists as long as the limit from the left is equal to the limit from the right.
Subsequently, one may also ask, is a closed dot a bracket?
You use brackets when you want to include the endpoint, and you denote this with a closed circle/dot. On the other hand, if you want to exclude the endpoint, you use a parenthesis, which is shown by an open circle.
What does a dot mean in a math equation?
In mathematics and scienceIn mathematics, a small middle dot can be used to represent product; for example, x y for the product of x and y. When dealing with scalars, it is interchangeable with the multiplication sign: x y means the same thing as x × y, but × is easily confused with the letter x.

Naming Objects Using Endpoints
Many objects in geometry such as line segments, angles, polygons, etc., can be named using endpoints:
Points A and B are endpoints for the line segment below. The line segment is named by its endpoints, AB or BA.
A ray on the other hand, has only one endpoint as shown below. The ray is named using its endpoint as the first letter, AB.
An angle can be named using the common endpoint of the two rays, as shown below. Rays AB and BC share endpoint B and form an angle. This angle can be named as ABC or, using just its endpoint, as B.
A polygon is formed by three or more-line segments. The polygon below, called a quadrilateral, is formed by segments AB, BC, CD, and AD, called sides. Each side intersects two other sides, at each endpoint. One way to name a polygon involves listing the endpoints of the polygon in sequence; the polygon below can be named ABCD or BCDA, among other names.

As A Degenerate Ellipse
A line segment can be viewed as a degenerate case of an ellipse, in which the semiminor axis goes to zero, the foci go to the endpoints, and the eccentricity goes to one. A standard definition of an ellipse is the set of points for which the sum of a point’s distances to two foci is a constant; if this constant equals the distance between the foci, the line segment is the result. A complete orbit of this ellipse traverses the line segment twice. As a degenerate orbit, this is a radial elliptic trajectory.
Why Is Endpoint Data Backup Important
Endpoint use is increasing in the business world due to workforce mobility, by which I mean the rarity that youre ever in your office, much less tethered to a desk. Traditional network-focused protocols are designed for the PC-era and the desktop. With an ever-growing amount of data outside the firewall on endpoint devices, IT needs to deal with security and communications in real time across varying locations and bandwidths. Adding to this risk are the possibly insecure apps loaded on employees ever-increasing number of devices, with consistent exposure to malware across Internet protocols.
IT teams solve for the challenges of endpoints using a variety of technologies, such as virtual private networks , that enable safe connection to the main, managed network.Endpoint cloud backup;technologieslike Druva also enable real-time backup of the data on endpoints, minimizing the risk of data loss. They provide IT the tools to manage corporate data on endpoints, such as the ability to remote wipe and create a trusted data store in the cloud.They can even be used to automatically detect a malware or ransomware attack, allowing an IT admin to address it immediately ;before it causes further damage.

Measurement Of Line Segment
A ruler is an instrument used in geometry. We use a ruler to draw a line segment. ;We use it also to measure length of a line segment.
A ruler is generally 1 ft long and is called One foot ruler. Sometime it is simply called scale. Some rulers are six inches long and are called half foot ruler. One edge of a ruler has scales marked in inches and the other edge has scales marked in cm.
We place the ruler with its edge along the line-segment AB with the zero mark of the ruler at the start point A of the line-segment. We read the mark on the ruler at the other endpoint B of the line-segment.

What Is A Ray In Geometry
A ray has a start point and it continues indefinitely to one direction only. It cannot expand to both directions like Line does. Take an example of a Torch Beam. The start point is the Torch, but the endpoint is not certain and it lights everything it touches. Even if you relocate the torch, the start point will never change.
Here is another example of a Ray XY:
Points to Remember about Rays
- A Ray has a start point and continues indefinitely to one direction only.
- You will always define the first point of the ray at the beginning . The endpoint can be given somewhere close to the arrowhead, but not on the arrowhead.

What Is The Slope Of Ab
When two lines are perpendicular, the slope of one is the negative reciprocal of the other. Try this Drag points C or D. Note the slopes when the lines are at right angles to each other. So for example in the figure above, the line AB has a slope of 0.5, meaning it goes up by a half for every one across.
Terms You Need To Know
A point shows location and has no size or dimension. A point is represented by a dot and is usually named with a letter of choice. In the graphic below, the points are labelled by a nearby letter.
A line is a set of points extends in two opposite directions without end. A line is one-dimensional and has no width. It is identified by naming two points on the line or by writing a lowercase letter of choice after the line.
The notation, for example, AB , is read as “line AB” and refers to the line that has points A and B.
A plane is a flat surface that has no thickness and extends without ending in ALL directions. It is a two-dimensional object. A plane is represented by a parallelogram and may be named by writing an uppercase letter of choice in one of its corners. I will go into detail about what a parallelogram is in future lessons. For now, think of a parallelogram as a “window pane.”For simplicity, you might want to think of a plane as an infinitely large sheet of paper.
The diagram below shows three points, a line, and a plane.
A line line segment is part of a line having two points, called endpoints. It also has points between the endpoints. A line segment does not have a set of CONTINUOUS points like a line does. Endpoint means that a line has a beginning and an end. The notation for a line segment in a bar over any letter of choice. Say AB has a bar over it, you would read it as “line segment AB.”
