Delta Symbol

The delta symbol represents the 4th greek letter. We have uppercase Delta Δ and lowercase Delta δ. Delta symbol has different meanings. The lower case symbol in math equations means the change of any amount (quantity) that can also be changed. In polynomial equations, it is used to describe the Discriminates and the area of a triangle. In physics, it represents the delta particles. It means the addition of heat in chemistry.

The uppercase delta used in engineering to denote deflection and in chemistry, it means partial change and magnetic shift. The word delta is used to call the Nile river delta which takes the shape of a triangle.

How to use and type Delta symbol code?

  • If your keyboard contains separate NumPad, you should be sure that it is enabled. If it is not, press the Num Lock key to activate it then press hold down the Alt key on the left side. Type the number that represents that character or the symbol you want to insert and then release the insert key.
  • For example, for the greek letter omega Ω press and hold Alt and the type 0234 and then release.
  • There is another method that works only for word documents. In this method, you should type the characters first then press Alt and X. For example ( 0234 + Alt + X for greek letter omega ).
  • If you have a keyboard that doesn't have NumPad here is what will work for you. Find the Function key ( FN ) then presses and hold the function key while holding press and release Num LK key; then release FN key. This method will activate the numeric keypad in your laptop.
  • Then do the same steps as in the previous example.
  • Notice that in IBM code you don't use 0 (Alt + 255 ) before the code which is different from the windows generator that requires to add 0 (Alt + 0255 ) before the code.

Something doesn't work?

  • The Num lock should always be enabled. If it is disabled when you are attempting an alt code, it may cause errors or unexpected results in some applications. For example, Alt+4 could be interpreted as Alt +, ← which causes the browser to go back if the Num lock is disabled.
  • If your laptop keyboard doesn't have a separate NumPad, you should hold FN button with Alt button while typing the code.
  • This method does not work for Linux system, but it is possible to use Unicode.
