Writing Equations using HTML and API on webpage

 HTML codes for writing equations

1) Roots:-

Code                    Output

√ 4 = 2            -->  √ 4 = 2

   

∛ 27 = 3         -->  ∛ 27 = 3

∜ 16 = 2         -->  ∜ 16 = 2

2) Superscript and Subscript text:-

<div>2² = 4</div>     --> 2² = 4

<div>3³ = 27</div>    --> 3³ = 27

<div>2⁴ = 16</div>    --> 2⁴ = 16

<div>A₁                       -->    A₁

3)Fractions:-

<p>7&nbsp;<span class="frac">⁴²<span>⁄</span>₇₃</span>.</p>                 --> 7 ⁴²⁄₇₃.

<p>(&nbsp;<span class="frac">⁴²<span>⁄</span>₇₃</span>)</p>                   --> ( ⁴²⁄₇₃)

4)Combinations:-

<p>&#8731; (&nbsp;<span class="frac">⁴²<span>⁄</span>₇₃</span>)</p> --> ∛ ( ⁴²⁄₇₃)

5)Complex Equations:-

MathJax --> API (application programming interface)  --> an external program/tool --> can call like other scripts. To make it work, following code need to be inserted in your HEAD tag:

<SCRIPT SRC='https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML'></SCRIPT>
<SCRIPT>MathJax.Hub.Config({ tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']]}})</SCRIPT>

Just write the right code for the formulas, and MathJax will convert it to formulas when the webpage is opened. Instead of a start and stop tag, you use $$ before and after. So, writing the solution to a second degree equations, the code looks like this:

2$ x = {-b \pm \sqrt{b^2-4ac} \over 2a}.2$ will look like

$$ x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$

2${df\over dx} = {df\over du} . {du\over dx}.2$ will look like

$${df\over dx} = {df\over du} . {du\over dx}$$

Soil reaction under eccentric loading for straight line variation of soil pressure 2$ P_1 = {W\over A}.(1+{6e\over b}) 2$ will look like

$$ P_1 = {W\over A}.(1+{6e\over b}) $$

Soil reaction under eccentric loading for Parabolic variation of soil pressure 2$ P_1 = {W\over A}.(1+{4e\over b}) 2$ will look like

$$ P_1 = {W\over A}.(1+{4e\over b}) $$

for Greek letters alpha write as \alpha

2$ The depth at partial flow d = ({D\over 2}-{D\over 2}.cos{\alpha\over 2}) 2$ will look like

$$ d = ({D\over 2}-{D\over 2}.cos{\alpha\over 2}) $$

Writing degree symbol (360^\circ)

2$ a = {\pi D^2\over 4}.{\alpha\over 360^\circ} 2$ will look like as

$$ a = {\pi D^2\over 4}.{\alpha\over 360^\circ} $$

Brackets can be made bigh using \left and \right, 2${C_D} = \left({D\over {D_T}}\right){\times}{\sum D} 2$ will look like $${C_D} = \left({D\over {D_T}}\right){\times}{\sum D} $$

for multiplication use \times

for sigma sign use \sum

Text

to write equation in text use \text{}

2$VDF = {\text{ total damaging effect}\over \text{Number of  vehicles weighed}}2$ will look like

$$VDF = {\text{ total damaging effect}\over \text{Number of  vehicles weighed}}$$

To rotate text in Table

<table border="1" font-size:="">

 <tbody>

  <tr>

  <td><span STYLE="writing-mode: vertical-lr;-ms-writing-mode: tb-rl; transform: rotate(180deg);">Sr.no</span></td>

\root {n}\of this syntax put before the expression for which n^th root is required.

for example  expression for Relative stiffness of the bar embedded in concrete (4rth root) 2$\beta =\root {4}\of {{k_{mds}{b_d}}\over {4EI}}$2 will look like

$$\beta =\root {4}\of {{k_{mds}{b_d}}\over {4EI}}$$

Table 

Merging columns & rows

    to merge columns one can use "colspan " 

    to merge rows one can use "rowspan" 

Example code

<table border="1" style="border-collapse: collapse;">

  <tbody>

    <tr>

      <td rowspan="4" style="writing-mode: vertical-rl; text-align: center;">Subtraction of Chainages</td>

      <td colspan="2" style="text-align: center;">Subtraction of Chainages</td>
