What is a Delta symbol?

A computer scientist or even a simple layman may stumble upon a simple symbol of the Greek alphabet delta Δ, which denotes a variety of meanings. This sign is a letter of the Greek alphabet and stands for the number four. A delta was formed from the letter of the Phoenician alphabet, which meant the direction, and more specifically the entrance. Some said it a triangle symbol.

Delta Symbol

Delta symbol on Windows

If your keyboard has a numeric keypad, then you can type the delta symbol using an Alt code – this consists of you pressing a few numbers while holding the Alt key. The numeric keypad is to the right of your keyboard – most keyboards in the desk have a numeric keypad. If you are using a laptop, you will only see the numbers on the top row of the keyboard and not on the right. To type the delta symbol on the keyboard, type 916 while holding down Alt.

Δ =Alt+916

  1. Press and hold Fn + NumLock to activate Number Lock.
  2. Hold down the Alt key and type 916.

Apple Mac Os or Mac book owners can use the Option + J keyboard shortcuts.

3 Ways to insert Delta sign In Microsoft Word

0 3 9 4 ➟ Alt + X = Δ

Type the English letter “D” instead of the character. Select it and in the top menu on the “Home” tab set the font “Symbol”. The letter will automatically turn into a symbol for delta.

Anywhere in the document, enter “0394” and press the Alt and X hotkeys. The numbers are converted to a character. The keyboard layout must be English. 0 3 9 4 ➟ Alt + X = Δ

On a full keyboard with a right numeric keypad, you can use the following method. Hold Alt and type 916. It is necessary to enter numbers on the right digital block.

Insert Delta symbol In Microsoft Excel

Copy and Paste the Delta Symbol a very quick and clean way to get the delta symbol in Excel is to copy it from somewhere else. It can be a delta symbol that you have already inserted into the worksheet, or you can copy it from a web page.

Below are the steps to insert the delta symbol (solid triangle/arrow symbol) in Excel using a keyboard shortcut:

  1. Select the cell where you want to insert the delta symbol.
  2. Press F2 to enter edit mode.
  3. Use the keyboard shortcut – ALT + 30 (you need to hold down the ALT key and then press 30 from your keyboard’s numeric keypad).

Note : This keyboard shortcut works only if you have a 10-key number pad on your keyboard. If you don’t have a numeric keypad, you must first enable number lock and then use this keyboard shortcut.

Insert Delta Δ δ symbol and difference sign in Office

Alt keys are the Easiest Way to write the Greek symbols. To put in the unlike “deltas” in a file, you can also go on as follows:

Click the Insert tab in your Office program and then the Special Characters menu item, characters at the following location:

DescriptionSymbolHexadecimalDecimal
Delta (large) = Alt key+916ΔU + 394916
Delta (small) = Alt key+948δU + 3B4948
Differential characters= Alt key+8710ΔU + 22068710

MICROSOFT PROGRAMS

If you are in Microsoft programs like Word or PowerPoint, you can type the delta symbol using Alt + X code. It can be used if you have a keyboard that does not have a numeric keypad and you are in a Microsoft program such as Word. To write delta symbol, press 0394 + Alt + X. This will bring up the delta symbol.

How to write the Delta sign?

If you are a mathematician or an accountant, at some point in your career you will have to write the delta symbol. The delta symbol is the fourth letter of the Greek alphabet and looks like a triangle; it is also transliterated as d.

In mathematics and accounting, delta means the variation of a variable or function. Unfortunately, most keyboards don’t allow you to type multiple math symbols like delta, so you need to use different codes or the character map on your Windows PC or Mac to type the delta symbol.

Where is this symbol used?

Nowadays, the symbol is used throughout the sciences for:

  1. Designation of the mathematical function of the same name ;
  2. Particle-delta notation in physics;
  3. Completeness designations in shipbuilding.
  4. And also this sign is popular in jewelry, tattoos and other symbols.

In addition to being used in the spelling of the Greeks, the symbol began to be actively used in mathematics, geometry, algebra, physics, chemistry and geography.

Let’s talk separately about the use of delta in each scientific area:

Geography:

Delta means in a geographical sense the initial part of a river, ocean or sea, has a semantic, rather than symbolic, literal concept and perception. Why is it the area where the river flows to be called that? It’s simple, it’s in the shape of this area, if you take a picture from above, and then the outflow of the river will have the shape of a regular triangle. The brightest representative with a pronounced delta is the Nile River (Egypt), which flows into the Mediterranean Sea, as well as the Amazon with its confluence into the Atlantic Ocean.

Physics:

In physics symbols are used in areas such as temperature, height, entropy, etc.

This would be expressed as follows:

∆T = (Tf – Ti) temperature difference

∆S = (Sf – Si) entropy difference

∆h = (hf – hi) height difference

Maths:

The notation of increment by the letter Δ was first used by the Swiss mathematician Johann Bernoulli. The delta symbol entered the general practice of using the symbol after the works of Leonard Euler in 1755. In mathematics, the capital delta (Δ) means “change.” In the case of X representing the speed of an object, and if accompanied by delta “Δx”, it refers to “change in speed”.

Chemistry:

In chemistry it means increase. It can be for example in Chemistry to denote an increase in temperature ∆T, let’s say you have T 1 = 6 ° C and they tell you that the temperature increased to T 2 = 10 ° C, and they ask you how much was the increase in the temperature? Give ∆T, and the answer is

∆T = (T 2) – (T 1) = (10 ° C – 6 ° C) = 4 ° C, that is, ∆T = 4 ° C.

T1 = initial temperature

T2 = final temperature

∆T = temperature increase
