How To Latex

AIR 538 Asish

I wont get into details about what Latex is, but will just post how to insert Latex images.

Latex basically does the function of the equation editor @goiit which for some reasons does not seem to work.

These are the steps that ull need to post pleasant looking mathematical equations/expressions in simple/compact forms.

STEP 1. Open the site codecogs.com/latex/eqneditor.php

STEP 2. Write the desired equation there (in the editor box)

STEP 3. Highlight the image generated and press Ctrl+C

STEP 4. Press Ctrl+V in the reply message box of your goiit image and your latexed image is ready

I am posting some examples of latex images also.

${^n}C_r$

$\frac{n!}{r!(n-r)!}$

$\sum_{i=1}^{n}{X_i}$

$\sum_{i=1}^{n}{X_i^2}$

$\sum_{i=1}^{n}{(X_i - \overline{X})^2}$

$X_1,\cdots,X_n$

$\frac{x-\mu}{\sigma}$

$\vec{F}=m \frac{d \vec{v}}{dt} +\vec{v}\frac{dm}{dt}$

$\left(x-1\right)\left(x+3\right)$

$\sqrt{a^2+b^2}$

$x = a_0 + \frac{1}{a_1 +\frac{1}{a_2 + \frac{1}{a_3 + a_4}}}$

$x = a_0 + \frac{1}{\displaystyle a_1 +\frac{1}{\displaystyle a_2 + \frac{1}{\displaystyle a_3 + a_4}}}$

$\vec{F}=m\vec{a}$

$\oint \vec{F} \cdot d\vec{s}=0$

$\begin{pmatrix} a_{11} & a_{12} \\ a_{21} & a_{22}\end{pmatrix}$

$\begin{pmatrix} a_{11}& a_{12} & a_{13}\\ a_{21} & a_{22} & a_{23}\\ a_{31}& a_{32} & a_{33} \end{pmatrix}$

$\begin{pmatrix} a_{11}& \cdots & a_{1n}\\ \vdots & \ddots & \vdots\\ a_{m1}& \cdots & a_{mn} \end{pmatrix}$

$\begin{pmatrix} 1 & 0\\ 0 & 1 \end{pmatrix}$

$\frac{\partial y}{\partial x}$

$\frac{d}{dx}c^n=nx^{n-1}$

$\frac{d}{dx}e^{ax}=a\,e^{ax}$

$\frac{d}{dx}\ln(x)=\frac{1}{x}$

$\frac{d}{dx}\sin x=\cos x$
