### Equations

Mathematics notation is easy to incorporate into an R Markdown document. Equations, Greek letters, and symbols can be included "inline" in sections delimted by \$ ... \$ (e.g., The mean is \$ \\bar{x} = 3.2 \$ $\rightarrow$ The mean is $\bar{x} = 3.2$). Using sections delimited by two dollar signs (\$ \$ ... \$ \$) will place the mathematical notation in display-mode as a separate paragraph. 

Raw markdown               | Knitted 
-------------------------- | ------
x^y                        | $x^y$
x_y                        | $x_y$
\\alpha, \\mu, \\sigma     | $\alpha, \mu, \sigma$
\\beta, \\beta_0, \\beta_1 | $\beta, \beta_0, \beta_1$
\\bar{x}                   | $\bar{x}$ 
\\hat{x}                   | $\hat{x}$ 
\\sqrt{x}                  | $\sqrt{x}$
\\sum                      | $\sum$
\\frac{x}{y}               | $\frac{x}{y}$

#### Displaying Blocks of Code Without Knitting/Evaluating

In some situations, you want to display text and R code without evaluating the R code. This is done by placing the code inside two sets of \`\`\` (You can see this in the .Rmd file).

```
This text is displayed verbatim / preformatted and $\sqrt{x}$ is not knitted.
```

#### Inline Equations

``` 
This equation $\bar{X} = \frac{1}{n} \sum X_i$ appears inline.
```

This equation $\bar{X} = \frac{1}{n} \sum X_i$ appears inline.

Note: in the .Rmd file you will see one code block within a set of \`\`\` (**not** knitted/evaluated) and one code block without the \`\`\` (knitted/evaluated)

#### Display-mode Equations

``` 
This equation $$\bar{y} = \frac{1}{n} \sum y_i$$ appears in display mode (indented on its own line)
