Math & Science ⇒ Additional flushed right Text in Math Environments

[arstaer]

Dear all,

I'm trying to set up flushed right text in the cases environment inside the align* environment. It's for the exam to specify how many points each linear equation in the equation system is worth. It doesn't seem to work that well as in normal text environment as I want it to be flushed right in the page but instead it's too close to the equation.

Code: Select all

\documentclass{article}
\usepackage{geometry}
\usepackage{mathtools}  
\usepackage{amsfonts,amssymb}

\begin{document}
  \begin{align*}
    \begin{cases}
      \mathbb{E}(r_A)&=r_f + \beta_A FP  ~\hspace*{\fill}[5~points] \\
      \mathbb{E}(r_B)&=r_f + \beta_B FP  \\
    \end{cases}
  \end{align*}
\end{document} 

Any idea what can be done in this case?


Thank you,
Arsenio

I would go a different way and define a command that places the points in the margin.

Code: Select all

\documentclass{article}
\usepackage{geometry}
\usepackage{mathtools}  
\usepackage{amsfonts,amssymb}
\usepackage{showframe}  % to show page dimensions
\usepackage{marginnote}

\newcommand*\points[1]{\marginnote{[#1~points]}}  % in the margin

\begin{document}
  \begin{align*}
    \begin{cases}
      \mathbb{E}(r_A)&=r_f + \beta_A FP \points{5} \\
      \mathbb{E}(r_B)&=r_f + \beta_B FP
    \end{cases}
  \end{align*}
\end{document}

This looks great!

Have never used the marginnote package. Are there any drawbacks to putting points on the margin, e.g., conflicts with other packages, problems when printing?


Thanks a lot mate,

Not that I know of. I regularly use it myself and haven't encountered any problems yet.
