River

A river is a natural waterway, which runs water diagonally the land from higher to lower elevations, and is the most significant part of the water cycle. The water within a river is commonly from rain through exterior runoff and release of stored water in natural reservoirs, like groundwater.

The start of a mountain river from their resource, all rivers flow downhill, naturally terminates in the sea or in a lake, all through a flowing together. In dry areas rivers at times end by losing water to evaporation. River water may as well gain way in to the soil or pervious rock, where it becomes groundwater. Extreme abstraction of water for use in industry, irrigation, etc., can as well source a river to dry before reaching its natural boundary.

What does Integration generally mean by its word?

Integration is a core model of advanced mathematics, particularly in the fields of calculus and mathematical analysis. Given a function f(x) of a actual variable x and an interval [a, b] of the real line, the integral is equal to the area of a region in the xy-plane bounded by graph of f, the x-axis, and the vertical lines x = a and x = b, by way of areas below the x-axis being subtracted.

The word "integral" may as well refer to the notion of ant derivative, a function F whose derivative is the given function f. In this casing it is called an indefinite integral, while the integrals discussed in this article are named definite integrals. Few authors maintain a distinction between ant derivatives and indefinite integrals.
