What Is Meant By The Delta Equivalent Sign

Divergence notation

What is the meaning of the delta equivalent sign?

I met this in a communication theory text. It said,

signaling rate: $r\overset 1/D$ symbols/s or also called baud.

  • 2$\begingroup$I met it in communication theory text, says that “signaling rate: r 1/D symbols/s or also called baud”$\endgroup$

It is a definition. Sometimes it is used with the slightly different meaning of “equal by definition”, to underline the difference w.r.t. “$:=$ ” which is the definition itself.


Delta Symbol: Partial Derivatives

The derivative of a function refers to a measure of infinitesimal changes in one its variables. Furthermore, the roman letter d is representative of a derivative.

Partial derivatives differ from regular derivatives. This is because the function consists of multiple variations but there is the consideration of one variable. The other variables certainly stay fixed. Also, a lower-case delta indicates partial derivatives. Therefore, the partial derivative of function f looks like this: f over x.

Transistor Circuit Diagram Symbols

Unlike a resistor symbol, a transistor symbol is used to indicate amplification or switches of power. There are three major transistor types: bipolar junction transistors , junction gate field-effect transistors , and metal oxide semiconductor field-effect transistors . Each type has its unique advantages and drawbacks. BJTs have high transconductance, whereas MOSFETs excel at low voltages. A useful mnemonic device for remembering which transistors are PNP and which are NPN is ânot pointing inâ for NPN and âpointing in proudlyâ for PNP.

So I’m aware that the triangle is uppercase delta which means the difference between: 10\Delta5=5

It’s already been answered pretty good. But just to clarify:\Deltax = x_-x_or the slope of a function:\frac = \frac -y_}-x_}Which you’ll find to be very similar to the definition of a derivative in calculus:\frac which basically means /Capital delta is looking for a specific answer while lower case is looking for another equation .

The upside-down triangle symbol tattoo meaning may vary from one group of people to another. For a long time, some used the shape to depict the form of the female reproductive organ or femininity. But today, it can be identified as a gay pride symbol. However, the sign can generally symbolise feminity, strength, and positivity.

When it is a pink triangle tattoo or purple, it signifies that the bearer is gay or supports the LGBTQ movement. Before, those who identified with this movement secretly used this peculiar tattoo when the laws were still unfriendly to gay people and gay rights. But with the world becoming more tolerant of gay rights, people show them openly.

Easy Ways To Insert The Delta Symbol In Excel

  • — By Sumit Bansal

When it comes to inserting symbols in Excel, things can get a bit complicated.

You either need to know the keyboard shortcut, or use the methods that are not very straightforward.

And there are a lot of symbols that many people need to insert regularly, such as the degree symbol, cent symbol, delta symbol, etc.

Note: In this tutorial, I have shown all the methods for the Greek Capital Letter Delta symbol . You can use the same methods for other delta symbols as well.

This Tutorial Covers:

The Eye Of Providence

The Eye of Providence, or the All-Seeing Eye, is another triangle symbol that is associated with Christianity. It is depicted as a triangle with an eye inside and represents divine providence or God keeping watch over humanity.

It has been used in Christian art to depict the Holy Trinity since Renaissance times and reminds believers that God constantly maintains the natural order of the universe.

This symbol is also famously found on the Great Seal of the United States, appearing on the reverse side of the one-dollar bill.

Some people believe that this symbol also secretly indicates the role of Freemasons in the creation of the United States. However, this image was only adopted by Freemasons some years after the Great Seal was created, so this conspiracy theory is unlikely to be true.

Native American Symbolism Home

In Native American culture, the triangle often represents the home for obvious reasons since a triangle is the shape of the tepee, the traditional conical tend of certain Native American tribes.

They may sometimes be depicted with other triangles inside the main triangle, representing the extended family, other members of the tribe and a sense of belonging.

Statics: Lesson 4- Vector Addition, Triangle Rule, and Cartesian and Vector Notation

I am getting started with electronics and decided to learn about the inner workings of the L293D. However, I found a symbol I don’t recognize, which is the triangle with 3 connections. There are four of them in the schematic.

At first I thought they were op amps, but those have 5 inputs.


They are drivers with enables. Basically they take low-current drive signals and amplify them to high-current capable of driving high-power devices, in this case motors. The wire going into the “back” of the triangle is the input signal, the wire coming out of the “front” of the triangle is the output drive, and the wire going into the “side” of the triangle is an enable input, turning the driver on or off.

Creating A Custom Autocorrect Shortcut For A Triangle Symbol

To add your own AutoCorrect shortcut for a triangle symbol:

  • Position the cursor in a Word document.
  • In the Symbols group, click Symbol. A drop-down menu appears.
  • If necessary, click the Symbols tab.
  • Select Wingdings 3 from the Font drop-down menu.
  • Enter the characters you want to use in the Replace dialog box such as tri1. Do not use spaces and keep in mind that AutoCorrect is case sensitive.
  • To use the AutoCorrect entry, type the characters you entered in Replace, such as tri1, and then press the Spacebar.

    The AutoCorrect dialog box appears as follows:

    The AutoCorrect shortcut is typically added to the Normal template so when you exit the program, Word will prompt you to save the Normal template. If your IT department has disabled modification of the Normal template, you won’t be able to use this method.

    Using The Insert Symbol Dialog Box

    This is a slightly longer way to insert the delta symbol, but once you have it inserted at one place, you can just copy paste it to reuse it.

    Here are the steps to insert the Delta symbol using the Insert Symbol dialog box:

    • In the Symbols group, click on the Symbols icon.
    • In the Symbols dialogue box that opens, select the Greek and Coptic as Font Subset.
    • Scroll down, find and select the delta symbol .

    This will insert the delta symbol in the selected cell.

    Physics Notation And Terminology

    Hans Laue

    The system of notation I am using in the applets in the contractwith Alberta Learning and in the text documents accompanying theapplets is unambiguous: different notation for different quantities.The system conforms with what you will find in general physics texts,with some minor differences.

    One difference is that general physics texts often don’t have asymbol for “distance traveled”. They just don’t calculate thedistance traveled and therefore don’t need a symbol. Also, althoughbooks are coming out now with a vector notation thatuses letters in boldface with an arrow on top, many books still useonly boldface. My applets and text use boldface plus the arrow. Thereason the arrow is important, I think, is because that is whatstudents will use in their handwriting. Students have a greattendency to omit the arrow, and so we must model good practice forthem. Anyway, the arrow is used also in the Alberta Education manuals.So the arrow is not an issue. I just would like to point out that notall textbooks use arrows and that this is one difference between thenotation proposed here and that found in general physics texts.

    Here is the system that I have used for years in first-yearuniversity teaching, both in instruction and in the present MAP andthe earlier CALiPH computer modules. I can recommend it.

    Time instant: t

    Time interval: Dt

    Distance traveled: s

    Straight-line distance between two points and magnitude of a displacement:d

    Position vector:

    Ancient Egypt A Symbol Of Protection

    golden triangles

    When we think of triangles, we must remember some of the largest triangles that have ever existed, those making up the sides of the Pyramids in Egypt.

    Although the pyramidal shape was adapted partly for practical reasons since the distribution of weight in a pyramid allowed ancient civilizations to construct great monumental architecture, the shape also has a symbolic meaning.

    The Pyramids were built as tombs for pharaohs, with the large base in contact with the ground and the tip of the structure pointing towards the sky and the sun.

    This can be seen as representing an ending for the physical body but a new beginning for the spirit as it could rise up into the sky to be closer to Ra, the god of the sun.

    In modern spiritual practices, pyramids are also thought to have special healing powers, and sleeping below a pyramid is believed to optimize the energies in your body.

    What Does The Triangle Imply In Physics

    In case you say it signifies you might be incorrect then you could possibly be correct for the reason that when we make use of the word triangle, were only employed for the prevalent form of triangle, which can be two intersecting lines.

    The most preferred style of triangle will be the triangle with a dot on it. This can be something in the first day of the month for the very first day of summer. It has nothing at all to perform with what the triangle indicates in Physics.

    Triangles and cones represent two of your properties of any triangle. From this definition we can see that the triangle and cone are about triangles and cones, as a result we will assume what were saying is about triangles and cones.

    What do the dot and also the circle have to do with one a further? Within the fourth year of higher college, I was told by the teacher that my life depended on something named The Influence Issue. She went on to explain that if it was under a certain level, I would not be permitted to visit college, keep residence, professional essay writers or be permitted to acquire a job that paid effectively.

    I was not delighted about this and asked what it meant. The class fell silent for quite a few minutes, when she started to inform me that it meant all the things had to be measured using a numerical value that would give a meaning to every single single word inside the English language.

    Different Types Of Triangles

    Before we talk about the meaning of triangles, we need to take a step back and remind ourselves of some basic geometry since there are several different types of triangles, and the symbolism can vary, depending on which type appears.

    Triangles can be classified according to one of two features their internal angles or the lengths of their sides.

    If the sides of a triangle are all equal, it is known as an equilateral triangle. The angles of an equilateral triangle are all equal too they all measure 60° so this type of triangle can be seen as the most perfect type of triangle and is a commonly used symbol.

    A triangle with two sides of the same length is called an isosceles triangle, and one with sides of three differing lengths is called a scalene triangle.

    If one of the angles of a triangle measures 90°, it is called a right-angled triangle. A triangle with all its angles measuring less than 90° is called an acute triangle whereas a triangle with one angle measuring more than 90° is called an obtuse triangle.

    These kinds of more irregularly shaped triangles are less commonly use as symbols since they dont have the same power as equilateral triangles or isosceles triangles.

    What Is An Upside

    The upside-down symbol also means the nabla. It originated from a semblance of a standing harp or an inverted letter of the Greek alphabet delta.

    It may mean an unstable triangular system, not necessarily an equilateral triangle that collapses or tilts over when placed to its vertices. Since it does not rest on its base, it becomes impossible to stand.

    What Does The Upside

    The inverted triangle symbol, or the upside-down triangle symbol, serves different purposes globally. Groups and organisations that have or use it deploy various forms of the triangle for their purpose. These forms have varying thicknesses on the sides with unique meanings. But today, most people look at it with suspicion or wariness compared to what groups and organisations used it for back then.

    When the upside-down triangle is displayed on the road as a traffic sign, it means yielding to other road users. This means that while on a particular lane, the driver facing the upside-down triangle is to give the right of way to the oncoming road users. However, when the upside-down triangle symbol appears in a truck, it is used to notify road users that the vehicle on which it appears is a slow-moving vehicle.

    Symbols Used In Modern Physics




    From the above text on physics symbols, we understand that in Physics, we use various symbols or notations to denote different quantities. The denotations make the representation of the quantities easier.

    It was also interesting to see that some physics symbols were very relatable while some were unrelatable . Also, we noticed that a particular symbol was related to more than one quantity.
