Referencing Equations \begin{equation} \label{eq:pythagorean} a_1^2 + b_1^2 = c_1^2 \end{equation} An example table can be seen in \ref{eq:pythagorean}. Also note how the "Equation" prefix is automatically added within the document text whenever the reference is called.

There are two basic types of formula: Inline formulas are surrounded by single dollar signs. For example, $f(x) = ax^2 + bx + c$ renders as f(x)=ax2+bx+c. Block formulas are surrounded by double dollar signs. For example, $$x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}$$ renders, on a separate line, as x=?b±?b2?4ac2a.

#LaTeXTip: remove equation numbering for separate lines by adding ?\notag? before \\ in the align environment. Use \begin{align*} and \end{align*} to switch off numbering entirely.

A line can APPEAR to have two different equations. but these really represent the same line as you would see if you divided the first equation by 2 or if you graphed the lines. The y-intercept of two perpendicular lines are b and ?2. The x-intercept are 3 and a, respectively.

For regular inline math that you want to never break across the line boundary, you could use \mbox{$... $} . Making this a rule seems a bit harsh, since longer expressions are typically allowed to break around binary and relational operators, which looks okay.

If it is inline equation, then use \allowbreak . Use it like: $x_1,x_2,x_3,\allowbreak x_4,x_5$. Latex will break equation in this place only if necessary.

Multiple Equations If we use the gather environment, every equation is centered. If we use the align environment and insert an & on every line where we wish the equations to be aligned (usually at some sort of equality symbol), the equations will be aligned.
