Dieting is the practice of ingesting food in a harmonized fashion to search out an exacting objective. In numerous cases the aim is weight loss, however some athletes look forward to gain weight and diets can as well be used to keep a stable body weight.

There are many kinds of diets:

The Weight-loss diets control the intake of exacting foods, or food in most cases, to lessen body weight. What works to drop off body weight for one person will not essentially work for another, because of the metabolic differences and lifestyle factors. In addition, for a variety of reasons, the greater part of the people discovers that it is very difficult to maintain major weight loss over time. There is some notion that losing weight promptly can actually make it harder to maintain the loss over time.

Exchange rate

In finance, the exchange rates that are different names are also known as the foreign-exchange rate, forex rate or FX rate between two currencies specify how much one currency is value in terms of the other. For example an exchange rate of 102 Japanese yen (JPY, ¥) to the United States dollar (USD, $) means that JPY 102 is worth the same as USD 1. The foreign exchange market is one of the largest markets in the world. By some estimate, about 2 trillion USD worth of currency changes hands every day.
The spot exchange rate refers to the current exchange rate. The forward exchange rate refers to an exchange rate that is quoted and traded today but for delivery and payment on a exact future date.

Divergence theorem in maths

In vector calculus, the divergence theorem, as well known as Gauss' theorem, Ostrogradsky's theorem, or Gauss-Ostrogradsky theorem is an answer that relates the flow (that is, flux) of a vector field through a surface to the behavior of the vector field inside the surface.

More accurately, the divergence theorem states that the outward flux of a vector field through a surface is equal to the triple integral of the divergence on the region in the surface. Intuitively, it states that the sum of every source minus the sum of all sinks gives the net flow out of a region.
The divergence theorem is the main result for the mathematics of physics, particularly in electrostatics and fluid dynamics.
