This image shows some kind of formula that could be converted to TeX. Storing formulas as images makes it harder to change them. TeX also helps making sure that they all use the same font and size. If you know how to set this formula in TeX, use this template with a parameter {{Use TeX|1=Here goes the formula }} Tips when using this template: Do put spaces in between adjacent {{s and adjacent }}s Do include the 1= Do not include the tags; by default: <math>...</math> tags will be added later If this is a chemical equation. add |2=chem to use <chem>...</chem> tags instead |2=math chem is an option if needed for color or alignment, but do include your \ces Any other values in the second parameter will be ignored Deutsch ∙ English ∙ italiano ∙ magyar ∙ Nederlands ∙ polski ∙ sicilianu ∙ svenska ∙ Ελληνικά ∙ български ∙ македонски ∙ русский ∙ 日本語 ∙ فارسی ∙ +/−
