   \titleformat{\chapter}[display]
     {\normalfont\sffamily\Large\bfseries\centering}

     {\thesection}{1em}{}

4. Add this line to adjust the chapter headings spacing:

   \titlespacing*{\chapter}{0pt}{30pt}{20pt}

5. Save preamble.tex and Typeset the main document equation.tex. Let’s see how the headings have changed:
