Each letter is considered to be the name of a variable and will be typeset as such. If you are typing text normally, you are said to be in text mode, but while you are typing within one of those mathematical environments, you are said to be in math mode, that has some differences compared to the text mode: Most spaces and line breaks do not have any significance, as all spaces are either derived logically from the mathematical expressions, or have to be specified with special commands such as \quad.Įmpty lines are not allowed. The equation* and displaymath environments are functionally equivalent. Furthermore, should a problem occur, the error messages may not be helpful. Displayed and automatically numbered equations. The following table summarizes them: Type.
Unlike most other environments, however, there are some handy shorthands to declaring your formulas. As math requires special environments, there are naturally the appropriate environment names you can use in the standard way. They can be distinguished into two categories depending on how they are presented: text - text formulas are displayed inline, that is, within the body of text where it is declared, for example, I can say that a + a = 2a within this sentence. Therefore, special environments have been declared for this purpose. X typesets maths notation differently from normal text. The mathtools package loads the amsmath package and hence there is no need to \usepackage. The mathtools package fixes some amsmath quirks and adds some useful settings, symbols, and environments to amsmath. If you are writing a scientific document that contains numerous complicated formulas, the amsmath package. X has most of the tools that you will need. If your document requires only a few simple mathematical formulas, plain La. It is also a large topic due to the existence of so much mathematical notation. X) became so popular within the scientific community. The fact that he succeeded was most probably why Te. X system was to create something that allowed simple construction of mathematical formulae, while looking professional when printed. One of the greatest motivating forces for Donald Knuth when he began developing the original Te.
