Stack Equation Record For Free

If you want to put text inside math mode, you can use \text{your text here}. If that doesn't work, add \usepackage{amsmath} before the line \begin{document}, or use \textrm{your text here}.

This can be used to stack something above something else; used in math mode. The first argument, top, is typset immediately above the second argument, bot; the former is set in the same math style as a superscript.

In large equations or derivations which span multiple lines, we can use the \begin{align} and \end{align} commands to correctly display the aligned mathematics. Here we use the ampersand ( & ) command to ensure the equations always line up as desired.

If you want to write several equations together then you can use the eqnarray environment. At the end of each equation you start a new line using \\ as usual. The eqnarray environment lets you align equations so that, for example, all of the equals signs "=" line up.

For equations longer than a line use the multline environment. Insert a double backslash to set a point for the equation to be broken. The first part will be aligned to the left and the second part will be displayed in the next line and aligned to the right.

Multiple Equations In general, the command \\ signifies a line break and within the correct math mode environment, it can start a new equation line. Try the example on the right which sets the same multiple equations in several ways. Observe that the equation environment does not even allow line breaks.

Use fleqn as an option in the document class. ... This will left align all the equation in the article. But if you want to left align some specific equation, then you can use amsmath package at the preamable and use environment flalign to align the equation to the left.
