Сommon font for formulas and text

Question

I use PSCyr to use TimesNewRoman. This command \renewcommand{\rmdefault}{ftm} does it succesfully for text and doesn't make corrections to math-mode. How can I use TimesNewRoman for formulas without XeLaTeX?

Answer 1

My suggestion is to leave PSCyr alone and use a more modern setup.

\documentclass{article}
\usepackage[russian]{babel}

\usepackage{tempora}   % Times like with Cyrillic support
\usepackage{newtxmath} % Times like for math

\begin{document}

Эрдэни Цырендоржиев

$\sin^2x+\cos^2x=1$

\end{document}

If you really want ftm:

\documentclass{article}
\usepackage[T2A]{fontenc}
\usepackage[russian]{babel}
\usepackage{newtxmath}

\renewcommand{\rmdefault}{ftm}
\DeclareSymbolFont{operators}{OT1}{\rmdefault}{m}{n}
\SetSymbolFont{operators}{bold}{OT1}{\rmdefault}{b}{n}

\begin{document}

Эрдэни Цырендоржиев

$\sin^2x+\cos^2x=1$

\end{document}
