Explanation of logical operator program
- && evaluates to 1 because both operands and is 1 .
- && evaluates to 0 because operand is 0 .
- || evaluates to 1 because is 1 .
- || evaluates to 0 because both operand and are 0 .
- ! evaluates to 1 because operand is 0 . Hence, ! is 1 .
- ! evaluates to 0 because is 1 . Hence, ! is 0 .
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.
E In Scientific Notation And The Meaning Of 1e6
You don’t need a calculator to use E to express a number in scientific notation. You can simply let E stand for the base root of an exponent, but only when the base is 10. You wouldn’t use E to stand for base 8, 4 or any other base, especially if the base is Euler’s number, e.
When you use E in this way, you write the number xEy, where x is the first set of integers in the number and y is the exponent. For example, you would write the number 1 million as 1E6. In regular scientific notation, this is 1 × 106, or 1 followed by 6 zeros. Similarly 5 million would be 5E6, and 42,732 would be 4.27E4. When writing a number in scientific notation, whether you use E or not, you usually round to two decimal places.

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.

Where Does Euler’s Number E Come From
The number represented by e was discovered by mathematician Leonard Euler as a solution to a problem posed by another mathematician, Jacob Bernoulli, 50 years earlier. Bernoulli’s problem was a financial one.
Suppose you put $1,000 in a bank that pays 100% annual compound interest and leave it there for a year. You’ll have $2,000. Now suppose the interest rate is half that, but the bank pays it twice a year. At the end of a year, you’d have $2,250. Now suppose the bank paid only 8.33%, which is 1/12 of 100%, but paid it 12 times a year. At the end of the year, you’d have $2,613. The general equation for this progression is:
where r is 1 and n is the payment period.
It turns out that, as n approaches infinity, the result gets closer and closer to e, which is 2.7182818284 to 10 decimal places. This is how Euler discovered it. The maximum return you could get on an investment of $1,000 in one year would be $2,718.

Example : Arithmetic Operators
// Working of arithmetic operators#include <stdio.h>int main
Output
a+b = 13a-b = 5a*b = 36a/b = 2Remainder when a divided by b=1
The operators +, – and * computes addition, subtraction, and multiplication respectively as you might have expected.
In normal calculation, 9/4 = 2.25. However, the output is 2 in the program.
It is because both the variables a and b are integers. Hence, the output is also an integer. The compiler neglects the term after the decimal point and shows answer 2 instead of 2.25.
The modulo operator % computes the remainder. When a=9 is divided by b=4, the remainder is 1. The % operator can only be used with integers.
Suppose a = 5.0, b = 2.0, c = 5 and d = 2. Then in C programming,
// Either one of the operands is a floating-point numbera/b = 2.5 a/d = 2.5 c/b = 2.5 // Both operands are integersc/d = 2
That Is A Lot Of Adding Up
But we don’t have to add them up, as there is a “shortcut”, because …
… finding an Integral is the reverse of finding a Derivative.
Like here:
An integral of 2x is x2 …
… because the derivative of x2 is 2x
That simple example can be confirmed by calculating the area:
Area of triangle = 12 = 12 = x2
Integration can sometimes be that easy!

Now For An Increasing Flow Rate
Imagine the flow starts at 0 and gradually increases :
As;the;flow rate increases, the tank fills up faster and faster:
- Integration: With a flow rate of 2x, the tank volume increases by x2
- Derivative: If the tank volume increases by x2, then the flow rate must be 2x
We can write it down this way:
The integral of the flow rate 2x tells us the volume of water: |

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.

Point:
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.
Line:
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.
Plane:
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.
Line Segment:
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.

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:
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 points 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.

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.
