Latex Incorporated :)

I have finally been successful at incorporating Latex and we can now type any equation!

$ R_{ \mu \nu } - \frac{1}{2}g_{\mu \nu} R + g_{\mu \nu} \Lambda = \frac{8\piG}{C^4}T_{ \mu \nu} $

See :)
And this is one of my favourite equations.

Using latex is very easy, you just need to know the commands.
Usha ma'am, satyajit, and Raghu are already experts at it :).

Here are a few examples:

$ s = \int L ( q, \dot{q} , t ) dt $

To type this equation, one has to type & s = \int L ( q, \dot{q} , t ) dt &
You just have to replace & with $$.
Any latex commands can be used by enclosing them between $$ .

Similarly

$ \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) $

is & \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) &

( again just replace & with $$ )

For those who want to use latex and want to know all the commands, here are some links that will help you:
