# Can anybody help to write the mathematical equation with latex

also, can anyone suggest me good pdf file for it to learn the coding maths in latex

Thank you

• Welcome. What did you try? Did you read about $...$ math mode? – Sigur Nov 7 '19 at 12:28
• not yet. i am trying to write a equation which i have posted as photo in my question – maths Nov 7 '19 at 12:30

• For instructions on dealing with math somewhat above the bare-bones basic $...$ (in-line) and equation (display) input, see the amsmath users guide and example paper – barbara beeton Nov 9 '19 at 19:44

For inline math, use $ delimiters: \documentclass{article} \usepackage{amsmath} \begin{document}$a_{\max} =  \max\limits_{0\le a\le\mathrm{argmin}(a(t))} a(t)\$
\end{document}


For display math, use $...$ delimiters for unnumbered equations, or one of the various environments, such as equation for numbered equations. Or, with the amsmath package, something from the align family of environments.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
thank you very much in advance.
\begin{align}
T_d=T_\mathrm{upper}-T_\mathrm{Lower}\\
%
T_\mathrm{upper} = \min\{t||a(t)|\ge a_\mathrm{threshold}\}\\
%
T_\mathrm{lower} = \max\{t||a(t)|\ge a_\mathrm{threshold} \}\\
%
a_\mathrm{threshold} = 10\% \max(|a(t)|)
\end{align}
\end{document}


• could you please help to write codes for these four equations. thank you very much in advance. 1. T_d=T_upper-T_Lower 2. T_Upper=min⁡{t||a(t)|≥a_Threshold} 3. T_Lower=max⁡{t│|a(t)|≥a_Threshold } 4. a_Threshold=10% max⁡(|a(t)|) – maths Nov 7 '19 at 14:41
• @maths See my edit. You really need to get a reference tutorial for basic LaTeX math. – Steven B. Segletes Nov 7 '19 at 15:11
• Thank you steven. Yes i am looking basic tutorial currently. – maths Nov 7 '19 at 15:16
