Abstract

This is a short summary of the paper. It introduces the main topic and purpose of the document.

1Introduction

Welcome to your first LaTeX document using the [LaTeX Documentclass Options Illustrated](https://texblog.org/2013/02/13/latex-documentclass-options-illustrated/) guide. The article class puts the title, author, and date directly on the first page instead of on a separate title page.

2Problems

  1. Solve the equation $$x^2 + 2x = 5$$
  2. Do the problem $$y = \sin{x} + 13\cos{x}$$
  3. 15. Tank \(T_1\) initially contains 50 gallons of pure water. Starting at \(t_0 = 0\), water that contains 1 pound of salt per gallon is poured into \(T_1\) at the rate of 2 gal/min. The mixture is drained from \(T_1\) at the same rate into a second tank \(T_2\), which initially contains 50 gallons of pure water. Also starting at \(t_0 = 0\), a mixture from another source that contains 2 pounds of salt per gallon is poured into \(T_2\) at the rate of 2 gal/min. The mixture is drained from \(T_2\) at the rate of 4 gal/min.

3Methodology

You can write equations easily:

\begin{equation} E = mc^2 \end{equation}
