LATEX is now enabled in this site

About 3 months ago, I tried to enable $LATEX$ for this site but sad to say, it did not work. My desire to enable this functionality opted me to contact my host company. But unfortunately, $LATEX$ is one thing that they will not enable in a shared hosting. I tried many ways, read and read, made a bunch of trial and error in my local machine and finally, the fruit of my labor, its good to savor. What a satisfaction.

What is $LATEX$ anyway?
For this is a math site, $LATEX$ is an absolute need. It will give us the ability to enter inline equations like $f(x) = x^2 + 6x – 4$ and can easily input Greek alphabet like $\alpha$ and $\theta$.

The following can be done easily using $LATEX$:
\[ \frac{\partial u}{\partial t} = h^2 \left( \frac{\partial^2 u}{\partial x^2} + \frac{\partial^2 u}{\partial y^2} + \frac{\partial^2 u}{\partial z^2} \right) \]

\[ \lim_{x \to +\infty}, \inf_{x > s} and \sup_K \]

\[ \lim_{x \to +\infty} \frac{3x^2 +7x^3}{x^2 +5x^4} = 3.\]

\[ \sum_{k=1}^n k^2 = \frac{1}{2} n (n+1).\]

\[ \int_a^b f(\beta)\,d\beta.\]

\[ \int_0^{+\infty} x^n e^{-x} \,dx = n!.\]

\[ \int \cos \theta \,d\theta = \sin \theta.\]

\[ \int_{x^2 + y^2 \leq R^2} f(x,y)\,dx\,dy = \int_{\theta=0}^{2\pi} \int_{r=0}^R f(r\cos\theta,r\sin\theta) r\,dr\,d\theta.\]

\[ \int_0^R \frac{2x\,dx}{1+x^2} = \log(1+R^2).\]

$$\det\left|\,\matrix{
c_0 & c_1 & c_2 & \ldots & c_{n\phantom{+1}}\cr
c_1 & c_2 & c_3 & \ldots & c_{n+1}\cr
c_2 & c_3 & c_4 & \ldots & c_{n+2}\cr
\vdots & \vdots & \vdots & \ddots & \vdots \cr
c_n & c_{n+1} & c_{n+2} & \ldots & c_{2n}} \right| > 0$$

and many more.

In the future, I will post in the Books section on how to use $LATEX$ to display these equations.

You can see the $LATEX$ code by clicking twice (double click) any of the formulas. A small code window will appear that contains the $LATEX$ code. You can close this code window by clicking a small square at the upper left corner of the code window.
