Which symbol represents a change in a quantity?

Explanation:
The change in a quantity is shown with the uppercase delta symbol, Δ. It represents the difference between a final value and an initial value, Δx = x_final − x_initial. The lowercase delta, δ, is used for small or infinitesimal changes, not the general change. When you see forms like Δt or ΔQ, they’re just applying that same idea to a specific quantity (change in time, change in charge). So the general symbol for a change is Δ.
