Introduction to MathJax

What is Mathjax?

MathJax allows you to include mathematics in your web pages, either using LaTeX, MathML, or AsciiMath notation, and the mathematics will be processed using JavaScript to produce HTML, SVG or MathML equations for viewing in any modern browser.

Installing MathJax on Your Website

The easiest way to install MathJax on your website is adding link of CDN(Content Distribution/Delivery Network) inside the head section of your website. You copy and paste following code just above closing head tag. You can place following code on body part of your website too. If you are using Blogger as your blogging platform you can add this code on your HTML post editor. It is not necessary to add this code for each post. You can add this code by adding HTML/JavaScript gadget for this script stored on CDN.  I added this code along with the codes of contact button.


<script async="" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML" type="text/javascript">

Let us Start MathJax

The support for TeX and LaTeX in MathJax consists of two parts: the tex2jax preprocessor, and the TeX input processor. The first of these looks for mathematics within your web page (indicated by math delimiters like $$...$$) and marks the mathematics for later processing by MathJax. The TeX input processor is what converts the TeX notation into MathJax’s internal format, where one of MathJax’s output processors then displays it in the web page.

The default, the tex2jax preprocessor defines the LaTeX math delimiters are $$...$$ and \[...\] for displayed mathematics, and \(...\) for in-line mathematics. Note in particular that the $...$ in-line delimiters are not used by default. That is because dollar signs appear too often in non-mathematical settings, which could cause some text to be treated as mathematics unexpectedly. For example, with single-dollar delimiters, ”The Raspberry Pi3 is of $35 while Raspberry Pi Zero W costs only $5" would cause the phrase "35 while Raspberry Pi Zero W costs only" to be treated as mathematics since it falls between dollar signs.

If you don't know LaTeX commands, don't bother about that. There is an awesome tool called Detexify. You have to just draw your mathematical symbol on the Detexify. It will find out corresponding code. The Detexify has Android app on Google Play Store. An example for LaTeX command is give below. We will discuss more about those commands in next post.

The following MathJax code will give you result \(\frac12\).

8051 Simple Programs

Sum of 8-bit Numbers Stored in Memory Here  we will discuss about 8051 programs but we can't discuss about all of the 8051 instructions. For programming 8051 we should know about assembler directives as well as instruction set.

Introduction to 8051 embedded C

For 8051 we need to include the file reg51.h. This file contains the all the definitions of 8051 registers. With this information C compiler produces hex file that can be downloaded into the ROM of the microcontroller. It is important to note that the size of the hex file produced by the assembly language is much larger than the hex file produced by C compiler. Apart from this fact, there is many reasons for writing programs in C instead of assembly: ●It is much easier and less time consuming to write programs in C assembly. ●C is more flexible; it is easier to modify and update. ●Programming in C allows to use code available in function libraries. ●Program written inC for one microcontroller is portable to other microcontrollers with little or no modifications. Data Types in 8051 Embedded C The table shown below lists the data types that are available in typical C51 compiler. The gives information about the size of the data variable and it's value range.

Frequency of Oscillation of RC Phase Shift Oscillator

Derivation of Frequency of Oscillation We have to find out the transfer function of RC feedback network. Feedback Circuit of RC Phase Shift Oscillator Applying KVL to various loops on the figure, we get, $$I_1 \left(R+\frac{1}{j \omega C }\right) -I_2R=V_i \text{ ....(1)}$$ $$-I_1R+I_2\left (2R+\frac {1}{j\omega C}\right)-I_3R=0\text{ ... (2)}$$ $$0-I_2R+I_3\left(2R+ \frac{1}{j\omega C}\right)=0\text{ ...(3)}$$ Replacing \(j\omega\) with \(s\) and writing equations in the matrix form, $$\begin{bmatrix}R+\frac{1}{sC} & -R & 0 \\-R & 2R+\frac{1}{sC} & -R \\0 & -R & 2R+\frac{1}{2sC} \end{bmatrix}\begin{bmatrix}I_1\\I_2\\I_3\end{bmatrix}=\begin{bmatrix}V_i\\0\\0\end{bmatrix}$$ Using Cramer's rule to find out \(I_3\), $$\text{Let, }D=\begin{bmatrix}R+\frac{1}{sC} & -R & 0 \\-R & 2R+\frac{1}{sC} & -R \\0 & -R & 2R+\frac{1}{2sC} \end{bmatrix}$$ \(|D|=\begin{vmatrix}R+\frac{1}{sC} & -R & 0 \\-R & 2R+\frac{1}{...
