Theorem: If f’(x) = 0 on [a,b] The f’(x) constant on [a,b]. i.e. f(x) = f(a) for all x belong to (a,b] Proof: Assume there is a special x-value and f(x)≠f(a) Then (f(x)-f(a)) / (x-a) = m ave ≠0 There is a point C in (a,x) with f’(c) = m ave ≠0 Then this contradicts the given fact that f’(x) =0 for all x belong to (a,b) So the assumption f(x) ≠f(a) must be fake and instead, f(x)=f(a) for all x belong to (a,b].

“加减乘除”怎么说？各种数学符号的英文表达，看完学渣变学霸！
不知大家还记得当年所画过的函数图吗？不停地标点，画线，有时候为了画出好看的弧度，甚至要多擦几遍才能做到...每一条函数都有不一样的形状，把它们组合起来，也许会有意想不到的效果噢
数学，相信对于不少人，特别是文科班女生的来说，都是一个大难题。
在考试时，靠的就是自己的英语来拉分。
那么，想要用英语来说出数学公式，又该怎么表达呢？
一. 首先区分一下Equations 和Formulas的使用
1. An equation等式 says that two things are equal. It will have an equals sign "=" like this:
x + 2 = 6
2. A formula公式 is a special type of equation that shows the relationship between different variables. 也是一种特殊的等式，只不过展示的是不同变量之间的关系
举个栗子：我们常用到的长方体的体积等于长X宽X高就是一个formula
V = lwh
V stands for volume, l for length, w for width, and h for height.
3. Algebra代数
不用多说，就是XY未知数，多年实战，你们懂的
二. 符号
要说公式，总不能只说个字母就完事吧，加减乘除先来一翻1.加号+ plus
x + 1：x plus one
2.减号- minus
x -1：x minus one
3.乘号x multiplied by
x times y; x multiplied by y
4.除号÷ over; divided by
x over y; x divided by y;
除了这些小学的算术题外，还有这些
1.约等于x ≈ y x is approximately equal to y
2.大于等于x ≥ y x is greater than or equal to y
3.小于等于x ≤ y x is less than or equal to y
4.区间 0 < x < 1 x is greater than zero and less than 1
5.平方 x² x squared
6.三次方 x³ x cubed
7.四次幂x4 ：x to the fourth; x to the power four
不知道又有多少人是像小编一样因为杨幂家独特的起名方式而把这个三次方给记住了呢？
根号：
平方根√root x; square root x; the square root of x
立方根∛the cube root of x
以此类推，其余的根表达就是：the nth root of x
绝对值|x| mod x; modulus x
运用以上综合表达组合：
(x + y)²：x plus y all squared
(x/y)²：x over y all squared
所以... 以上你学到了么？
其实抛开刻板，数学也可以变得很浪漫。
在《爱情公寓》中，为了向宛瑜表白，展博就引用了卡内基·梅隆大学的一位教授David Feinberg的一首诗歌——《孤独的根号三》（The Square Root of Three）
I fear that
I will always be a lonely number like root three
A three is all that's good and right
Why must my three keep out of sight Beneath a vicious square-root
sign?
我害怕，
我会永远是那孤独的根号三。
三本身是一个多么美妙的数字，
我的这个三，
为何躲在那难看的根号下。
I wish instead I were a nine
For nine could thwart this evil trick with just some quick arithmetic
I know I'll never see the sun
As 1.7321
Such is my reality, A sad irrationality
我多么希望自己是一个九，
因为九只需要一点点小小的运算，
便可摆脱这残酷的厄运。
我知道自己很难再看到我的太阳，
就像这无休无止的1.7321……
我不愿我的人生如此可悲。
When hark! What is this I see,
Another square root of a three
直到那一天，我看到了，
另一个根号三。
Has quietly come waltzing by
Together now we multiply
To form a number we prefer
Rejoicing as an integer
翩翩舞动而来，
我们彼此相乘，
得到那梦寐以求的数字，
像整数一样圆满。
We break free from our mortal bonds
And with a wave of magic wands Our square-root signs become unglued And love for me has been renewed
我们砸碎命运的枷锁，
轻轻舞动爱情的魔杖。
我们的平方根，已经解开。
我的爱，重获新生。
