I wanted to type an equation in LaTeX. But it is too long to fit into one line. It involves big arrays with many columns so I cannot split it. I wanted to reduce the font size so that it can fit in one line. However, `\small`

doesn't work in the `equation`

environment.

The following illustrates font size alterations in mathmode:

This yields:

Note that:

`\displaystyle`

gives the command to switch the math font size to normal size for displayed formulas.`\textstyle`

is used to go back to normal size font for inline formulas.`\scriptstyle`

is used to set the math font to a size used for subscripted and superscripted symbols.`\scriptscriptstyle`

provides the normal size for doubly subscripted and superscripted symbols.When using the

`\scalebox`

command from the`graphicx`

package one can specify the width (or height) and the other dimension will be scaled proportionally. In a similar manner you can specify both dimensions, but in this case it is all about aesthetics. Therefore we have the following under the`\scalebox`

command:`\scalebox{h-dimension}{v-dimension}{content to be scaled}`

: both dimension stated.`\scalebox{h-dimension}{content}`

: both arguments (`h-dim`

and`v-dim`

) scaled with respect to the stated dimension.
