I want to write a "big" equation, not in display-math mode — as given by the equation environment — but in inline-math mode, say
$E=mc^2$
How can I enlarge it?

This defines a new environment myequation with the help of environ package:
\NewEnviron{myequation}{%
\begin{equation}
\scalebox{1.5}{$\BODY$}
\end{equation}
}
Code:
\documentclass[a4paper,12pt]{article}
\usepackage{amsmath}
\usepackage{graphicx} % \scalebox
\usepackage{environ}
\NewEnviron{myequation}{%
\begin{equation}
\scalebox{1.5}{$\BODY$}
\end{equation}
}

Here I'll be trying a small example... First, I am writing an inline equation here: $a + b$; also comparing plain number 123 vs. $123$ as inline equation -- and here, below, I'm using display equation:
%% Don't leave this line empty
\begin{myequation}%
f(y) = a \cdot k^{y} %
\end{myequation}
%
... and finally, I'm having a closing sentence, just to have some text after the display equation.

Example, how this can be typeset:
\documentclass[a5paper]{article}
\usepackage{amsmath}
\newcommand*{\transpose}{\mathrm{T}}
\newcommand*{\vc}[1]{\mathhbf{#1}}
% \vec and \vector are already defined
\begin{document}
\begin{equation}
\label{q-def}
\vc{q} = (\mu_1, \mu_2, \dots, \mu_{n-1}, \mu_{n})^\transpose
\end{equation}
Equation~\eqref{q-def} defines vector $\vc{q}$.
\end{document}
Or as matrix without commas:
\documentclass[a5paper]{article}
\usepackage{amsmath}
\newcommand*{\transpose}{\mathrm{T}}
\newcommand*{\vc}[1]{\mathbf{#1}}
\begin{document}
\begin{equation}
\label{q-def}
\vc{q} =
\begin{pmatrix}
\mu_1 & \mu_2 & \dots & \mu_{n-1} & \mu_{n}
\end{pmatrix}^\transpose
\end{equation}
Equation~\eqref{q-def} defines vector $\vc{q}$.
\end{document}
Second question
The equation can be typeset as:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
L = \log(l) = \sum_{i=1}^{N} \bigl(
\log (
\mathbf{s}(\exp \{ \mathbf{Q} t_i\})
\mathbf{q}
)
\bigr)
\]
\end{document}

Will one of
\large,\Large,\LARGE,\huge, or\Hugedo? Observe that because these commands are text-mode commands, they must be executed before entering math mode.Note the use of the curly braces to limit the scope of the size-setting switches.
