equation与formula的不同

本文主要是介绍equation与formula的不同，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

In math, an equation is a mathematical statement saying that two amounts or values are the same. A formula is a series of numbers or letters that represent a mathematical rule. 能被solve的是equation.

In science, a formula is a series of numbers or letters that represent a scientific rule.

formula [Origin: 'small form', from forma; FORM] a method or set of principles that you use to solve a problem or to make sure that something is successful ……的方法或原则，和recipe意思差不多。

• The formula for water is H₂O. 分子式
• Infant formula, baby formula or just formula or baby milk, infant milk, false milk, or first milk, is a manufactured food designed and marketed for feeding to babies and infants under 12 months of age 儿童配方奶
• a formula for a happy marriage 美满婚姻的原则。处方是prescription
  • prescirbe [Origin: praescribere 'to write at the beginning, order']
  • describe [Origin: describere, from scribere 'to write']
  • inscribe [Origin: inscribere, from scribere 'to write'] carefully cut, print, or write words on sth, esply on the surface of a stone or coin
• Formula 1 racing cars 一级方程式赛车。此处formula意为classification

What is the difference between equation and formula?

Equations appear frequently in mathematics because mathematicians love to use equal signs... In your case, "mpg = distance/gallons" is best understood as "a formula in the form of an equation", which means that in this instance the two words are interchangeable.

Equations and Formulas

Sometimes a formula is written without the =. For xxample, the formula for the volume of a box is lwh but in a way the ="is still there, because we can write V = lwh if we want to. 长方体的体积 = length * width * height

Logarithms are common in formulas used in science, to measure the complexity of algorithms and fractals, and appear in formulas for counting prime numbers.

六级/考研单词: mathematics, equate, recipe, infant, manufacture, prescribe, seldom, quart, prime

中文有“等式”、“方程”和”公式“，“解方程”，没有“解等式”。

汉典

• 数学中代数两端相等的式子，称为「方程」。
• 方：办法，做法……
• 程：衡量，考核……
• 一秉合十六斛；一斛hú本为十斗，后来改为五斗。

九章算术 : 方程

今有上禾三秉，中禾二秉，下禾一秉，实三十九斗；上禾二秉，中禾三秉，下禾一秉，实三十四斗；上禾一秉，中禾二秉，下禾三秉，实二十六斗。问上、中、下禾实一秉各几何？

方程的起源及发展史 

中国古代数学著作<九章算术》大约成书于公元前200~50年，其中有专门以“方程”命名的一章。这一章中所说的方程实际上就是现在人们所说的一次方程组，方程组由几个方程共同组合而成，它的解是这几个方程的公共解。“方程”一章中以一些实际应用问题为例，并给出了用方程组的解题方法。
