\documentclass{article}
\usepackage{lettrine}
\begin{document}
\lettrine[lines=2]{T}{HERE} has been considerable interest in solving the convex unconstrained optmization problem.
\end{document}

附一个 Plain TeX 风格的解法。

\documentclass{article}
\newcommand{\resizefont}[1]{\fontsize{#1}{#1}\selectfont}
\begin{document}
\noindent\hangafter-2\hangindent18pt
\smash{\lower10pt\hbox to 0pt{\hskip-\hangindent\resizefont{35pt}\selectfont T\hfill}}%
{HERE}
has been considerable interest in solving the convex unconstrained optmization problem.
\end{document}
