Common Mathematical Symbols in Markdown - treenabalds/How-To GitHub Wiki

Could you print a list of common mathematical symbols in Markdown?

Certainly! Here's a handy list of common mathematical symbols and how you can represent them using Markdown with LaTeX syntax:

Basic Operators

Symbol LaTeX Syntax Rendered Output
Addition + $+$
Subtraction - $-$
Multiplication \times $\times$
Division \div $\div$

Comparison Symbols

Symbol LaTeX Syntax Rendered Output
Equals = $=$
Not Equals \neq $\neq$
Less Than < $<$
Greater Than > $>$

Set Theory and Logical Operators

Symbol LaTeX Syntax Rendered Output
Element of \in $\in$
Not Element of \notin $\notin$
Subset \subset $\subset$
Superset \supset $\supset$

Greek Letters

Letter LaTeX Syntax Rendered Output
Alpha \alpha $\alpha$
Beta \beta $\beta$
Gamma \gamma $\gamma$
Delta \delta $\delta$

Miscellaneous Symbols

Symbol LaTeX Syntax Rendered Output
Infinity \infty $\infty$
Square Root \sqrt{x} $\sqrt{x}$
Integral \int $\int$
Partial Derivative \partial $\partial$

To render these symbols in Markdown, use a math block with double dollar signs ($$) for equations or single dollar signs ($) for inline math. For example:

Inline: $x^2 + y^2 = z^2$
Block: $$x^2 + y^2 = z^2$$

Slight Adjustment

This Markdown text wrapper \(x^2 + y^2 = 9\) didn't work for me, so I used $x^2 + y^2 = 9$ instead, and then it did work:

$x^2 + y^2 = 9$

How do you do +/- in Markdown?

To write the "plus/minus" symbol ((\pm)) in Markdown using LaTeX, you can use the following syntax:

  • For inline math, wrap the LaTeX code in single dollar signs:

    $ \pm $
    

    This will display as $ \pm $.

  • For a block equation, wrap the LaTeX code in double dollar signs:

    $$ \pm $$
    

    This will display as:

    $$ \pm $$

If you're using a Markdown editor that doesn't support LaTeX directly, you can simply write +/- as plain text. Let me know if you'd like to explore more math symbols! 😊

How do you place the long numerator of a fraction in parentheses so you can place the denominator under everything?

To write a fraction where the numerator is enclosed in parentheses and the denominator is underneath in Markdown using LaTeX, you can use the \frac command. Here's how:

Syntax Example

$$
\frac{(\text{Numerator Goes Here})}{\text{Denominator Goes Here}}
$$

Explanation:

  • \frac{...}{...} specifies the numerator and denominator.
  • Wrapping the numerator with parentheses: (\text{...}) ensures it is enclosed properly.

Example in Action:

If the numerator is something like $x^2 + 3x - 1$ and the denominator is $2x + 5$, the Markdown would look like this:

$$
\frac{(x^2 + 3x - 1)}{2x + 5}
$$

This would render as:

$$ \frac{(x^2 + 3x - 1)}{2x + 5} $$

This format is useful for clearly displaying complex fractions, especially in equations or mathematical documentation. Let me know if you'd like more tips for LaTeX in Markdown! 😊

So does this give the quadratic formula? $$\frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$$

Yes, that's absolutely correct! The expression:

$$ \frac{-b\pm\sqrt{b^2 - 4ac}}{2a} $$

is the quadratic formula. It is used to find the solutions (roots) of a quadratic equation in the form:

$$ ax^2 + bx + c = 0 $$

Here’s how the formula works:

  • $a$ is the coefficient of $x^2$.
  • $b$ is the coefficient of $x$.
  • $c$ is the constant term.
  • The term under the square root, $b^2 - 4ac$, is called the discriminant, and it determines the nature of the roots (real, imaginary, distinct, or equal).

It's an incredibly useful tool in algebra! Let me know if you'd like me to dive deeper into how to use it or its applications. 😊
