The delta symbol is often used in math to represent the change in a variable. For example, if you have the equation y = x + 5, the delta would be 5 because the delta is the difference between two numbers. In this equation, the delta is the difference between the variables x and y....
Upper-case delta (Δ) often signifies "change" in mathematics. For example, if the variable x stands for the movement of an object, then Δx (delta x) means "the change in movement." Scientists use this mathematical meaning of delta often in physics, chemistry, and...

Limit: Denoted by the symbol $\lim$, it represents the value that a function approaches as its input approaches a certain value. Derivative: Denoted by the symbol $\frac{df(x)}{dx}$, it represents the rate of change of a function with respect to its input. Integral: Denoted by the ...
The letter sha is also used in distribution theory for the “Dirac comb,” an infinite sum of evenly spaced delta functions. I’d seen the Dirac comb before, but I don’t recall Ш being used as a symbol for it. Sha is apparently an exception that proves the rule that Cyrillic letters...
