\begin{block}{Problem Solving Strategy}
Important when solving textual problems:
\begin{itemize}
\pause
\pause
\item Draw a diagram.
\pause
\item Introduce notation, function names for the quantities.
\pause
\item Express given information and goal using the notation.
\pause
\item Write equations relating the quantities.
\pause
Eliminate dependent variables (in the previous example we have
eliminated the radius as it was dependent on the height).
\pause
\item Use the chain rule to differentiate both sides
w.r.t. $t$.
\pause
\item Solve for the unknown rate, and substitute the given information
into the resulting formula.
\end{itemize}
