Writing Mathematical expressions

Use Markdown to display mathematical expressions on velog.

We can represent mathematical expressions, such as $x=0$, by using the dollar symbol ($) on both sides.

$ x=0 $

This sentence uses $ delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$

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

for examples,

• When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are $x = {-b \pm \sqrt{b^2-4ac} \over 2a}$

  	$ax^2 + bx + c = 0$
  	$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$

• The Cauchy-Schwarz Inequality
  $\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$

  $$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

• To split $ 100 in half, we calculate $100/2$

  	To split <span> $ </span>100 in half, we calculate $100/2$
