Noun
/əˌprɒksɪˈmeɪʃən ˈfɔːrmjʊlə/
The term "approximation formula" refers to a mathematical expression that provides an estimate or close representation of a quantity or function. Such formulas are widely used in various fields including mathematics, physics, and engineering to simplify calculations or to make predictions based on available data. They serve to provide easier computation when exact formulas are not feasible or when a precise answer is unnecessary.
Frequency of Use: The term is commonly used in academic, technical, and scientific contexts, particularly in written materials like research papers, textbooks, and technical manuals. It is less frequently used in casual oral speech.
Ученый применил формулу приближения, чтобы оценить распределения заряда в молекуле.
In calculus, an approximation formula can help in calculating the area under a curve when the exact integral is difficult to find.
В математическом анализе формула приближения может помочь в вычислении площади под кривой, когда точный интеграл сложно найти.
The engineer presented an approximation formula to simplify the complex dynamics of the mechanical system.
While "approximation formula" may not directly appear in idiomatic expressions, the concept of approximation is often used in expressions related to estimation and generalization. Here are some idiomatic expressions along with example sentences:
Чтобы спланировать бюджет, нам нужно получить грубую оценку вовлеченных затрат.
In the ballpark
Её расчеты были приблизительными, хотя и не точными, они помогли нам быстро принять решения.
To put it mildly
Приближение нашего графика было, мягко говоря, чрезмерно оптимистичным.

The word "approximation" comes from the Latin "approximare," meaning "to come near," composed of "ad-" meaning "to" and "proximare," meaning "to be near." The term "formula" comes from Latin "formula," which means "a small form” or “a rule," derived from “formare,” meaning “to form.” Together, "approximation formula" indicates a calculated guide or formula that brings one closer to the desired value.
