<h2>Computation of Definite Integrals.</h2>
		<p>In computing definite integrals it is important to observe that when the integral is known to exist the limit can be calculated on any properly chosen subset of the&nbsp;<tiny-math-inline formula="S_\delta"></tiny-math-inline>'s. So we&nbsp;have that if <tiny-math-inline formula="S_{\delta_1}"></tiny-math-inline>,&nbsp;<tiny-math-inline formula="S_{\delta_2}"></tiny-math-inline>, ... is any sequence of sums such that&nbsp;<tiny-math-inline formula="\displaystyle\mathop{L}_{n\doteq\infty}\delta_n=0"></tiny-math-inline>, then</p>
		<tiny-math-block formula="\mathop{L}_{n\doteq\infty} S_{\delta_n} = \int_a^b f(x)dx."></tiny-math-block>
		<p>One case of this kind occurs when&nbsp;<tiny-math-inline formula="\xi_k"></tiny-math-inline>&nbsp;is taken as an end-point of the interval <tiny-math-inline formula="{x_{k-1}}{x_k}"></tiny-math-inline> and all the&nbsp;<tiny-math-inline formula="\Delta_kx"></tiny-math-inline>'s are equal. Then we have</p>
		<tiny-math-block formula="\displaystyle \int_a^b f(x)dx =  \mathop{L}_{n\doteq\infty} \sum_{k=1}^n f(a+k\Delta x)\Delta x,  \text{ where }  \Delta x=\frac{b-a}{n}."></tiny-math-block>
		<p>A simple example of this principle is the proof of the following&nbsp;theorem.</p>

Basic setup

To set up the Math plugin user interface in the editor:

  • add math to the plugins option in the editor configuration;

For example:

  selector: 'textarea',  // change this value according to your HTML
  plugins: 'math',
  toolbar: 'math',

How to Use

To work with math elements, follow these steps:

  1. Enable Math Plugin

    1. Open the TinyMCE editor with the Math plugin enabled.

  2. Insert or Edit Math Elements

    1. Click the Math plugin icon in the toolbar.

    2. This opens the Math dialog.

    3. Select preferred language

    4. Enter Math formula in the textarea.

    5. Choose preferred text wrap

  3. Preview and Save

    1. Check Math formula output in preview.

    2. Review the final Math equation in the preview section.

    3. Click the save button in the Math dialog.

    4. The Math equation is inserted into the editor, wrapped accordingly based on the chosen text wrap.

Formula Tag Wrapping

  1. The Math dialog wraps the inserted formula with a specific tag.

  2. The choice of tag depends on the selected text wrap option in the dialog:

    1. For block (Text above and below) text wrap, the tag used is <tiny-math-block>.

    2. For inline (Inline with text) text wrap, the tag used is <tiny-math-inline>.
