Math & Science ⇒ Reducing font in equation

[ruchir_iit]

Hi,
I wanted to type an equation in latex. But it is too long to adjust in one line. It involve big arrays with many columns so I cannot split it. I wanted to reduce the font so that it can adjust in one line. However, \small doesn't work in {equation} environment.

Can anyone help me??

Decrease the font size outside the equation environment and switch back to normal size right after it.

Code: Select all

\small
\begin{equation}\label{eqn:label}
  % math expression
\end{equation}
\normalsize

Best regards
Thorsten

Hi Thorsten,

Thank you for your help. Still \small did not work but \footnotesize worked. May be I'll attach the image of the equation if you need to know it.

[...] May be I'll attach the image of the equation if you need to know it.

The code in the sense of a minimal working example (MWE) would be much more interesting. Perhaps you should think about modifying your type area.

I'm also interested in a solution for this problem. Here is a matrix that I would be very happy to be able to show without having to separate its parts. I've tried the \footnotesize but apparently that wasn't enough.

Code: Select all

\begin{subequations}
  \begin{align}
    H^&=\left[
    \begin{array}{ccc}
      -2 \left(-L_y \left(p q_2-r q_0\right)-L_z \left(q q_0+p q_3\right)+L_x \left(q q_2+r q_3\right)\right) & 2 \left(L_x \left(r q_0+q q_1\right)-L_z
      \left(p q_0-q q_3\right)-L_y \left(p q_1+r q_3\right)\right) & -2 \left(L_x \left(q q_0-r q_1\right)+L_z \left(p q_1+q q_2\right)-L_y \left(p q_0+r q_2\right)\right) \\
