    Welcome to TeX.SX! Add \usepackage[sc]{mathpazo} or \usepackage{newpxtext,newpxmath} to the preamble and remove the \renewcommand lines. – egreg Oct 06 '17 at 12:36

    Note also that it's recommended to not use $$ .. $$ for display math in LaTeX. Use \begin{equation*} .. \end{equation*} (requires \usepackage{amsmath}) or \[ .. \] instead. See Why is \[ … \] preferable to $$? – Torbjørn T. Oct 06 '17 at 12:47
  • Please confirm that you want to change both the text font and the math font to Palatino. (The title of your query is a bit confusing, as it seems to suggest that you want Palatino only for math material but not for text material.) – Mico Oct 06 '17 at 15:15
