英文介绍数学公式

英文介绍数学公式

英文介绍数学公式:轻松掌握基础与进阶技巧在英文世界中,数学公式是沟通数学概念和逻辑关系的重要工具。

下面,我们将一起探索一些常见的数学公式,并了解如何在英文中准确地介绍它们。

1. 基本数学公式(1)加法公式:Addition Formula当我们需要计算两个或多个数的总和时,可以使用加法公式。

例如,3 + 4 = 7,在英文中表达为 "Three plus four equals seven."(2)减法公式:Subtraction Formula减法公式用于计算两个数之间的差值。

例如,8 5 = 3,可以表述为 "Eight minus five equals three."(3)乘法公式:Multiplication Formula乘法公式用于计算两个或多个数的乘积。

例如,6 × 7 = 42,英文表达为 "Six multiplied seven equals fortytwo."(4)除法公式:Division Formula除法公式用于计算一个数被另一个数除的结果。

例如,21 ÷ 3 = 7,可以表述为 "Twentyone divided three equals seven."2. 进阶数学公式(1)平方公式:Square Formula平方公式用于计算一个数的平方。

例如,x² 表示 x 的平方,在英文中表达为 "x squared."(2)平方根公式:Square Root Formula平方根公式用于求解一个数的平方根。

例如,√16 = 4,可以表述为 "The square root of sixteen is four."(3)指数公式:Exponential Formula指数公式用于表示一个数的幂次方。

例如,2^3 = 8,英文表达为"Two raised to the power of three equals eight."2. 高级数学公式及其应用(1)三角函数公式:Trigonometric Functions在解决几何问题时,三角函数公式尤为重要。

加减乘除数字 英语表达

加减乘除数字 英语表达

1. “加”用plus,and或add表示;“等于”用is,make,equal等词表示。

2+3=? 可表示为: How much is two plus three?2+3=5Two plus three is five.Two and three is equal to five.Two and three make five.Two added to three equals five.If we add two to/and three, we get five.二加三等于五2. “减”用 minus或 take from表示10-6=? How much is ten minus six?10-6=4Ten minus six is four.Take six from ten and the remainder is four.Six (taken) from ten is four.十减去六等于四3. “乘”用time(动词)或multiply表示3X4=? How much is three times four?3X4=12Three times four is/are twelve.Multiply three by four,we get twelve.Three multiplied by four makes twelve.三乘以四等于十二4. “除”用divide的过去分词形式表示16÷4=? How much is sixteen divided by four?16÷4=4Sixteen divided by four is four.Sixteen divided by four equals/gives/makes four.十六除以四等于四。

五、分数表示法1. 分数是由基数词和序数词一起来表示的。

基数词作分子,序数词作分母,除了分子是“1”以外,其它情况下序数词都要用复数形式。

Distinctions made in writing are often not made explicit in speech;thus the sounds fx may be interpreted as any of:fx,f(x),f x,F X,F X,−−→F X.The difference is usually made clear by the context;it is only when confusion may occur,or where he/she wishes to emphasise the point,that the mathematician will use the longer forms:f multiplied by x,the function f of x,f subscript x,line F X,the length of the segment F X,vector F X.Similarly,a mathematician is unlikely to make any distinction in speech(except sometimes a difference in intonation or length of pauses)between pairs such as the following:x+(y+z)and(x+y)+z√ax+b and√ax+ba n−1and a n−1The primary reference has been David Hall with Tim Bowyer,Nucleus,English for Science and Technology,Mathematics,Longman1980.Glen Anderson and
