\chapter{The First Chapter}

\begin{exercise}
  Compute the derivative of the following function:
  \begin{equation*}
    f(x) = \sin((\sin x)^2)
  \end{equation*}
\end{exercise}
\begin{solution}
  The derivative is:
  \begin{align*}
    f’(x) &= ( \sin((\sin x)^2) )'
           = \cos((\sin x)^2) \cdot 2\sin x \cos x
  \end{align*}
\end{solution}

\begin{exercise}
  Compute the derivative of the following function:
  \begin{equation*}
    f(x) = \sin((\sin x)^2)
  \end{equation*}
\end{exercise}
\begin{solution}
  The derivative is:
  \begin{align*}
    f’(x) &= ( \sin((\sin x)^2) )'
           = \cos((\sin x)^2) \cdot 2\sin x \cos x
  \end{align*}
\end{solution}

\chapter{The Second Chapter}

\begin{exercise}
  Compute the derivative of the following function:
  \begin{equation*}
    f(x) = (x^2+1) \sqrt{x^4+1}
  \end{equation*}
\end{exercise}
\begin{solution}
  The derivative is:
  \begin{align*}
    f’(x) &= ( (x^2+1) \sqrt{x^4+1} )'
           = 2x\sqrt{x^4+1} + \frac{2x^3(x^2+1)}{\sqrt{x^4+1}}
