Add mathematical formulas to the experiment notebook

FizziQ's Text Input module is a sophisticated component that allows users to enter and display rich text, with special support for mathematical formulas in LaTeX. This user guide will guide you through the various features available.


1. Standard text entry

  • The interface offers a text field where you can enter comments, observations or explanations.

  • The text is automatically formatted and displayed in a readable font.

  • In display mode, if no text is present, a "Write a comment" message is displayed.



2. Support for mathematical formulas (LaTeX)

Manually inserting formulas

  • You can insert mathematical formulas directly using LaTeX syntax, either using the $$formula$$ format or the [formula] format


Automatic conversion of formulas

  • The module has an automatic converter that detects and transforms simple mathematical expressions into LaTeX code.

  • For example, if you write [x_1^2], it will automatically be converted to $$x_{1}^{2}$$.

  • Types of expressions recognized automatically:

    • Indices: x_1 → $$x_{1}$$

    • Exponents: x^2 → $$x^{2}$$

    • Fractions: (a+b)/(c+d) → $$\frac{a+b}{c+d}$$

    • Square roots: sqrt(x) → $$\sqrt{x}$$

    • Greek letters: alpha, beta, etc. → $$\alpha$$, $$\beta$$, etc.



3. Formula Editor Interface

The formula editor offers an intuitive interface organized into tabs:

"Basic" tab

  • Fractions

  • Square root

  • Exhibitors

  • Clues

  • nth root


"Advanced" tab

  • Integrals

  • Are

  • Products

  • Boundaries

  • Matrices

  • Derivatives

  • Systems of equations

  • Vectors


"Symbols" tab

  • Complete collection of Greek symbols (lowercase and uppercase)

  • Alpha, Beta, Gamma, etc.



4. Display and Editing Modes

  • Display mode: displays text with correctly rendered LaTeX formulas

  • Edit mode: allows you to modify text and formulas

  • "Validate" button: saves the changes and returns to display mode

  • Support for PDF export: the module can adjust its display for PDF export



Conclusion

The text input module makes it easy to create scientific documents with complex mathematical formulas, making your observations and analyses more accurate and professional.
