| text | either a braced argument, or a \startformula ... \stopformula block |
Description
Place a displayed math formula, including equation number.
The text argument is typically a \startformula ... \stopformula block instead of a literal braced argument.
Examples
Example 1
\placeformula[formula:aformula] \startformula y=x^2 \stopformula \placeformula \startformula \int_0^1 x^2 dx \stopformula
Numbering tricks
If you wish to begin the numbering anew you can add \resetnumber before \placeformula:
\placeformula[formula:aformula] \startformula (x+y)^2 = x^2 + 2xy + y^2 \stopformula \resetnumber[formula] \placeformula \startformula \int_0^1 x^2 dx = {1 \over 3 } \stopformula
If you wish to start the numbering at a certain number, say at 100, you can add \setnumber before \placeformula:
\setnumber[formula][100] \placeformula[formula:aformula] \startformula (x + y) ^3 = x^3 + 3x^2y + 3xy^2 + y^3 \stopformula \placeformula \startformula \int_0^1 x dx = {1 \over 2} \stopformula
