Most of these are just the abbreviation of the trigonometric function with simply a backslash added before the abbreviation. LaTeX assumes that each equation consists of two parts separated by an & and that each equation is separated from the one before by an &. If there are several equations that you need to align vertically, the align environment will do it: \begin{ align* } 2x - 5y & = 8 \\ 3x + 9y & = -12 \end{ align* } Open this amsmath fragment in Overleaf. How do I align things in the following tabular environment? It's not sufficient either because you may encounter $\equiv$ to mean an equivalence relation, especially in modulo arithmetic. \begin{array}{ccc}[t], or use [b] to ensure the rows are bottom-aligned.

Here are some commonly used math commands in LaTeX: Notice that with fractions with a 1-digit numerator and a 1-digit denominator, we can simply group the numerator and the denominator together as one number. Mathematically, the use of equals and not equal symbols is much more. But because the colon is a lighter symbol _it_looks_ the $a$ is further away. As mentioned before, the ampersand character & determines where the equations align. we have $f(x)=x$ for all $x$. I had to \usepackage{amsmath} in the preamble first, though.

Thank you. and notation in your document. However the second definition should be. In this case it means "identically equal" and is a shortcut for saying that a function is defined or that some identity holds for all function values, in contrast to $f(x)=x$ which could also mean a fixed-point equation (that is, $f$ is given and one looks for specific $x$).
