Here are some examples that I will go over in the midterm review. If you notice any typos or errors, feel free to let me know in the comments. You can add math symbols to your comments using LaTeX syntax surrounded by dollar signs. For example, the line

D\lim_{x \to \infty} f(x) = \frac{1}{2}D

with the D’s replaced by dollar signs becomes

$\lim_{x \to \infty} f(x) = \frac{1}{2}$.
