The triangle symbol, or delta, is the upper-case Greek symbol (Δ) which is used to mean a change in value or difference and also used to denote the discriminant of a quadratic formula which is used to indicate the number of solutions in a particular quadratic equation.∆: Means “change” or “difference”, as in the equation of a line’s slope: 2.Delta Symbol: Change
Uppercase delta (Δ) at most times means “change” or “the change” in maths. Consider an example, in which a variable x stands for the movement of an object. So, “Δx” means “the change in movement.” Scientists make use of this mathematical meaning of delta in various branches of science.

What does ∆ mean in calculus?
The two most common meanings are as the difference and the discriminant. The lowercase delta is used in calculus to mean the distance from the limit. The two meanings of the uppercase delta have formulas you can use to calculate them.
What does ∆ mean in physics?
In general physics, delta-v is a change in velocity. The Greek uppercase letter Δ (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).
Is a triangle a symbol for change?
The capital version of the Greek letter delta is written as a triangle like this: Δ. It is used in physics as a symbol to represent change, which is interesting because the triangle can also represent change. Part of the reason the triangle is such a powerful symbol is that it represents harmony and balance.
What does ∆ mean in Greek?
Delta (uppercase Δ, lowercase δ) is the fourth letter of the Greek alphabet. In the Greek numeral system, it has the value of four. Originally, the letter delta derived from daleth (the Phoenician letter), which meant door.
What is ∂ called?
The symbol ∂ indicates a partial derivative, and is used when differentiating a function of two or more variables, u = u(x,t). For example means differentiate u(x,t) with respect to t, treating x as a constant. Partial derivatives are as easy as ordinary derivatives!
