  {\large\bf Statement on calculators}
\end{center}


\section{Intro}
\label{sec:intro}

This statement explains the policy on calculators used during the exams
in Analysis in M.E.~I.


\section{Acceptable calculators}

In principle, any real calculator is acceptable, but I need to draw the
line somewhere between a calculator and a computer.

\begin{enumerate}
  
\item If it has a qwerty type keyboard, implemented in hardware or
  software, it is not a calculator.

\item If it has a screen more than $384\times216$ pixels, it is not
  a calculator.

\item Communications capability of any type is not acceptable.

\end{enumerate}

Exceptions may be made on a case-by-case basis.


\section{Acceptable operations}

The normal operations of a calculator, such as multiply, divide, add,
substract, change sign, exponentiate, and the standard math functions
as found on my Ti 30 Xa calculator (sin(h), cos(h), tan(h), exp,
and their inverses) do not have to be explained.

Anything else must be step-by-step {\em derived}, showing all intermediate
results.  But feel free to {\em check} your derivations using your
advanced calculator.
