What is Delta in Mathematics?
In mathematics, delta is the term used to describe a change in something, such as the slope of a line or the derivative of a function at a certain point. In addition, it can also mean the difference between two values, or the rate of change in a function.

In the field of mathematics, delta can be a confusing concept for students to understand. Luckily, there are plenty of online delta tutors available who can help you learn this important mathematical term.
Deltas are a type of landform where a river flows from an inland source to the sea or an estuary. A delta can take several different forms, depending on the factors that influence its formation. These factors include the tidal range and the offshore energy conditions that affect river flow.
The shape of a delta can vary significantly, too. Some deltas are narrow, while others are wide. The narrow end of a delta empties into the sea, while the wide end stays inland.
A delta is created by the movement of a river that deposits stream-borne sediments onto the shore. This sediment deposits more quickly than it can be removed by waves and ocean currents.
Most rivers do not form a delta, though some are able to deposit a large amount of sediments. For example, the Columbia River in Canada and the United States deposits enormous amounts of silt into the Pacific Ocean, but powerful waves and currents sweep this material away as soon as it is deposited.
In some cases, a river may have to cross an estuary, such as Chesapeake Bay, before it can form a delta. These rivers will usually divide into multiple channels or streams before rejoining to form a delta.
Deltas can be formed by tidal freshwater or estuaries, and they can also be formed when a river runs over an ancient lake bed. A tidal freshwater delta, for instance, occurs when a river meets Chesapeake Bay.
An inland delta is created when a river passes over an area of ancient lake water before returning to the sea. Examples of inland deltas are the California Delta and the Mississippi River Delta.
Some deltas are fan-shaped, such as the Nile Delta in Egypt. These Deltas are more bowed or curved than other types of Deltas, and they tend to have coarser sediments than other Deltas.
Deltas have been crucial in human history, because they provide access to flat land for farming and freshwater for sanitation and irrigation. They also offer easy access to the sea for trade and transportation.
Onesicritus of Astypalaia referred to the triangular shape of the mouth of the Indus River as a “delta.” Celoria notes that the term was likely coined by Greek historian Herodotus, who wrote fourteen times about the region’s history.
