Open an example of the amsmath package in Overleaf The standard LaTeX tools for equations may lack some flexibility, causing overlapping or even trimming part of the equation when it's too long. Thanks for contributing an answer to TeX - LaTeX Stack Exchange! I have used \begin{equation} to number my equations and would like to form a list of them in my front matter, similar to that created for list of figures or list of tables An easy way to produce subordinate equation numbers of the form (1.3a) (1.3b) (1.3c) for selected groups of equations. A solution using array (no packages needed): Here is a way to do it, with the dcases and spreadlines environments, from mathtools. Systems of equations in three variables that are inconsistent could result from three parallel planes, two parallel planes and one intersecting plane, or three planes that intersect the other two but not at the same location. The double backslash works as a newline character. Basic equations in LaTeXcan be easily "programmed", for example: As you see, the way the equations are displayed depends on the delimiter, in this case \[ \] and \( \). The output is very similar to the previous answers. 8 posts • Page 1 of 1 ... 2007 3:55 am . and I have equations in the section before the subsection, the numbering will be something like 1.0.1 or if I have equations in the chapter before any section the numbering will be 0.0.1. Numbering each line of equation in Latex. To overcome these challenges, you can use the "asmmath" package. This environment must be used inside an equation environment. I want the first equation to be on the left too. I am a beginner in Latex and I would like to know how I can write this system of equations, But I couldn't get the absolute value symbol as shown in the figure above and also I couldn't display the s=jw under the absolute value symbol and also the equations aren't aligned. For example, Trimming or Overlapping of equations when equations are very long. Does the Construct Spirit from Summon Construct cast at 4th level have 40 or 55 hp?
