Big Delta

Big Delta, often represented as Δ (delta), is a symbol used in mathematics and science to denote a change or difference in a quantity. For example, if you measure the temperature today and it’s 20°C, and yesterday it was 15°C, the change in temperature (Δ temperature) is 5°C. It helps us understand how much something has increased or decreased between two points. Big Delta is useful across disciplines, from physics and engineering to statistics, providing a clear way to express differences or variations in data or measurements.
