## What does δ mean in science?

δ+: A symbol which indicates that an atom or region with a deficiency of electron density, often because of resonance delocalization, electronegativity differences, or inductive effects..

## What is the symbol for angle?

symbol ∠In geometry, an angle can be defined as the figure formed by two rays meeting at a common end point. An angle is represented by the symbol ∠.

## What is Angle ABC?

Angle ABC is a straight angle, or 180°. Angle f, g, and h together must add to 180°. Try again. Angle ABC is a straight angle, or 180°.

## What does ∆ y mean in math?

It is simply the difference, or change, in a certain quantity. When we say delta y, for example, we mean the change in y or how much y changes. Discriminant is the second most common meaning of the uppercase delta.

## What does the triangle symbol mean in math?

It’s a greek symbol, pronounced “delta”. When used in mathematics it typically means “change in”, for example, Δx/Δt. which is shorthand for (x2-x1/t2-t1), which is this example refers to an average rate of change, as opposed to instantaneous rate of change, which is expressed as a derivative: dx/dt.

## What do maths symbols mean?

< Less Than and > Greater Than. This symbol < means less than, for example 2 < 4 means that 2 is less than 4. ... ≤ ≥ These symbols mean 'less than or equal to' and 'greater than or equal to' and are commonly used in algebra.

## What is DOS short for?

DOS stands for Disk Operating System and is the computer program no personal computer can do without. It exists in two forms. The one supplied for IBM Personal Computers is known as PC-DOS. All other compatible personal computers use MS-DOS.

## What does reverse triangle mean?

The nabla is a triangular symbol resembling an inverted Greek delta: or ∇. The name comes, by reason of the symbol’s shape, from the Hellenistic Greek word νάβλα for a Phoenician harp, and was suggested by the encyclopedist William Robertson Smith to Peter Guthrie Tait in correspondence.

## What does ∆ mean in physics?

In general physics, delta terms change and delta-v is simply a change in velocity. The Greek uppercase letter delta is the standard mathematical symbol to represent change in some quantity. Depending on the situation, delta-v can be either a spatial vector (Δv) or scalar (Δv).

## What does δ mean in calculus?

The lowercase letter δ (or 𝛿) can be used to denote: A change in the value of a variable in calculus. A Functional derivative in Functional calculus. An auxiliary function in calculus, used to rigorously define the limit or continuity of a given function.

## What does ∆ mean?

A (usually small) change in value. Often shown using the “delta symbol”: Δ Example: Δx means “the change in the value of x”
