Math & Science ⇒ amsart | Equation Formatting

[newbie123]

I added an equation into at list, but for some reason a (1) shows up before the equation. Also, the equation gets moved to the middle of the line. How do I fix this?

If it helps, my document reads:

Code: Select all

\documentclass[11pt]{amsart}
\usepackage{geometry}                % See geometry.pdf to learn the layout options. There are lots.
\geometry{letterpaper}                   % ... or a4paper or a5paper or ... 
%\geometry{landscape}                % Activate for for rotated page geometry
%\usepackage[parfill]{parskip}    % Activate to begin paragraphs with an empty line rather than an indent
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{epstopdf}
\DeclareGraphicsRule{.tif}{png}{.png}{`convert #1 `dirname #1`/`basename #1 .tif`.png}

\title{SATMathII}
\author{Cathy}
%\date{}                                           % Activate to display a given date or no date

\begin{document}
\maketitle
\section{Conic Sections}
\subsection{Parabolas}
	\begin{itemize}
	\item equidistant from \textbf{point} and \textbf{directrix}
	\item \begin{equation}(y-k)^2=4p(x-h) \end{equation}
	\item focus: (h+p, k)
	\item directrix x=h-p
	\item distance from parabola to focus and directrix: |p| 
	\end{itemize}





\end{document}

I added an equation into at list, but for some reason a (1) shows up before the equation.

It is the equation number. The class amsart puts the number on the left side. If you change the amsart to article, you get it on the right side.

Also, the equation gets moved to the middle of the line. How do I fix this?

The equation is always centered unless you want it otherwise. What do you want to fix? Please give some more detail about what you want.


Regards.

Welcome to the board.

This is not a MWE so it will be a lot easier to help if you provide a such in the future.

Regarding your problem, this is how it is defined in the [url=http://mirrors.ctan.org/macros/latex/required/amslatex/amscls/doc/amsclass.pdf]amsart[/url] class. (See page 7.)

Hi,

welcome to the board!

amsart is a class for publishing for the AMS (American Mathematical Society) in their specific style. If you publish for AMS, it's probably required to use exactly this formatting. If you don't, you don't need to choose amsart and "fix" that style. You could use the AMS math features by loading the amsmath package with other classes, such as article, recommended by mas:

Code: Select all

\documentclass[11pt]{article}
\usepackage{amsmath}

It will help if you tell us what you want. How exactly should it look.

Judging by your code, your nametag is well chosen. Here is a few pointer to get you started. There are diffenrent way to write mathematical formula with latex. When you use

Code: Select all

some text
\begin{equation}
    f(x) = x^2
\end{equation}
more text

latex create un numbered equation, centered on a new line, with a number for future reference. Use it when the equation to put emphasis on important formula.

If you want your formula to act like normal text, you can use inline math by putting it between dollar signs, like this

Code: Select all

some text $f(x) = x^2$ more text

There are many others depending on the situation. Have a look at this pdf file which describe it with more details

ftp://ftp.ams.org/pub/tex/doc/amsmath/s ... -guide.pdf

Here is a modified version of your code. I've added inline math to each of your formula.

Code: Select all

\documentclass[11pt]{amsart}
\usepackage{geometry}                % See geometry.pdf to learn the layout options. There are lots.
\geometry{letterpaper}                   % ... or a4paper or a5paper or ... 
%\geometry{landscape}                % Activate for for rotated page geometry
%\usepackage[parfill]{parskip}    % Activate to begin paragraphs with an empty line rather than an indent
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{epstopdf}
\DeclareGraphicsRule{.tif}{png}{.png}{`convert #1 `dirname #1`/`basename #1 .tif`.png}

\title{SATMathII}
\author{Cathy}
%\date{}                                           % Activate to display a given date or no date

\begin{document}

\subsection{Parabolas}

	\item equidistant from \textbf{point} and \textbf{directrix}
	\item $(y-k)^2=4p(x-h)$
	\item focus: $(h+p, k)$
	\item directrix $x=h-p$
	\item distance from parabola to focus and directrix: $|p|$
