Text Formatting ⇒ vert alignment of math in minipage

[jaybz]

How can I add horizontal space between these minipages and still have the boxes aligned at the top? hspace seams to have no effect.I also need captions at the top of each box which are aligned horizontally to their respective box. I will also be adding two or three more sets of boxes to the page later.

Code: Select all

\usepackage[top=.5in, bottom=1in, left=0.5in, right=0.5in]{geometry} 
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\begin{document}

\begin{center}
\begin{minipage}[t]{.25\linewidth}
\vspace{0pt}
\centering
\fbox{$\displaystyle
  \begin{alignedat}{2}
    sin(\,x+y\,) &= sin(x)cos(x)\,+\,cos(x)sin(y) \\
    sin(\,x-y\,) &= sin(x)cos(x)\,+\,cos(x)sin(y) \\
    cos(\,x+y\,) &= cos(x)cos(y)\,-\,sin(x)sin(y) \\
    cos(\,x-y\,) &= cos(x)cos(y)\,+\,sin(x)sin(y) \\
    tan(\,x+y\,) &= \frac{tan(x)+tan(y)}{1-tan(x)\,tan(y)} \\
    tan(\,x+y\,) &= \frac{tan(x)-tan(y)}{1+tan(x)\,tan(y)} \\
  \end{alignedat}

\hspace*{40pt}
\end{minipage}%

\fbox{$\displaystyle

    sin^{2}(x) &= \frac{1-cos(2x)}{2} \\
    cos^{2}(x) &= \frac{1+cos(2x)}{2}  \\
    tan^{2}(x) &= \frac{1-cos(2x)}{1+cos(2x)}  \\

Hi,

place the \hspace* command outside the minipage environment. You'll also have to increase the width of the first minipage to prevent an overfull box.

Thank you that's almost got it but how do I put a caption above each box?
