Question

Example for @SolomonZelman
\[\int_1^4 \sqrt{x} dx= \frac{2x^\frac{3}{2}}{3} |_1^4 = \\ \frac{2(4)^\frac{3}{2}}{3}-\frac{2(1)^\frac{3}{2}}{3} \\ =\frac{2(2)^3}{3}-\frac{2}{3}=\frac{16}{3}-\frac{2}{3}=\frac{14}{3}\]

Answer 1

Mine is better

Answer 2

\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~F(x)~{{\Huge |}_{a}^{b}}}\)

Answer 3

\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~F(x)~{{\Huge |}_{a}^{b}}}\) and it is inline

Answer 4

I made it up though,

Answer 5

ok you can show me
but I probably won't care to remember :p

Answer 6

`\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~F(x)~{{\Huge |}_{a}^{b}}}\)`

Answer 7

I am putting | with a size huge
but I am bounding the size Huge like this:

{ `{`\Huge | `}`_{a}^{b}}

Answer 8

\huge{ } won't bound the size
{ \huge } will bound the size.

Answer 9

What I was trying to ask thjough...

Answer 10

Is, if there is a natural, designed for this latex, or not?

Answer 11

I have only ever typed F(x)|_a^b

Answer 12

I never tried to look up if there is a "natural way" to type it

Answer 13

it is easy to remember.

(Once it is typed from eq. editor INTO the text)

1) you change [ ] to ( )
2) add " \displaystyle " (to the integral latex, in front)
3) and your " | " thingy, bound with size "\Huge"

Answer 14

Answer 15

they actually do that same thing here

Answer 16

\left.\frac{x^3}{3}\right|_0^1
\[\left.\frac{x^3}{3}\right|_0^1
\]
except they do left and right thingy

Answer 17

I was working on it, but luckily I came up with this, \(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~F(x)~{{\Huge |}_{a}^{b}}}\)

Answer 18

Wait

Answer 19

yours,
\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~~\left.F(x)\right|_a^b}\)

mine
\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~F(x)~{{\Huge |}_{a}^{b}}}\)

Answer 20

your is high wit a fraction only, that is how "left and right" make it

Answer 21

I can do it though

Answer 22

wikepedia's:
\[\int_a^bf(x)dx=\left. F(x) \right|_a^b\]
It doesn't look that different from mine

Answer 23

\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~F(x)~\left.\color{white}{\frac{.}{.}}\right|_0^1}\)

Answer 24

I am putting a white fraction there in the mid

Answer 25

So I don't understand why the \left. \right
it doesn't seem to give it anything extra

Answer 26

\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=~F(x)~\left.\color{white}{\frac{\frac{\frac{\frac{}{}}{\frac{\frac{}{}}{}}}{\frac{\frac{}{}}{\frac{}{}}}}{\frac{\frac{}{}}{\frac{}{}}}}\right|_a^b}\)

Answer 27

jk

Answer 28

I am putting black white fractions on top of each other.

Answer 29

```
\(\large\color{red}{\displaystyle\int\limits_{a}^{b}f(x)~dx=
~F(x)~{{\Huge |}_{a}^{b}}}\)
```
would be the ideal, for now I guess. (until, and if, I come up with something new)

Answer 30

tnx for putting this question, I guess wiki doesn't know any latex either.

Answer 31

lt looks like it knows some things

Answer 32

does, but not enough I guess. I outsmarted it:)

Answer 33

@ganeshie @iambatman @Kainui
Chance 4 u to see. (whenever you have time)
Check it out. (latex)


\(\large\color{green}{ \displaystyle \int\limits_{a}^{b}f(x)~dx=
~F(x)~{ {\Huge |}_{a}^{b} } }\) :D


\(\large\color{blue}{ \Downarrow }\)
```
\(\large\color{green}{ \displaystyle \int\limits_{a}^{b}f(x)~dx=
~F(x)~{ {\Huge |}_{a}^{b} } }\)
```
\(\large\color{blue}{ \Uparrow }\) (bounded the | with { } )

Answer 34

@ganeshie8 (failed to tag u, sorry)

Answer 35

Ahh thats useful, i tried to stop `\Huge` earlier but failed, i know how to stop it now thanks :)

Answer 36

i use below usually

` \left. \dfrac{x^2}{2} \right|_a^b` produces below

\[ \left.\dfrac{x^2}{2}\right|_a^b\]

` \right| ` sees stuff between the bars and scales the vertical bar accordingly
