\problem{Problem 1 (2 points)}
%---------------------------------------------------------------
Find the value of the expression
\begin{equation}
	(3.2)^{4}-1+\ln(3)
\end{equation}
where $\ln$ is the natural logarithm (use \texttt{log} in Matlab).

\problem{Problem 2 (3 points)}
%---------------------------------------------------------------
Find the value of the expression
\begin{equation}
	\sin(2 \pi + \pi/3) + \tan(\pi/8)
\end{equation}
What variable name should you type to get numerical $\pi$ representation?
Does Matlab use degree or radians for angular measure?

\problem{Problem 3 (2 points)}
%---------------------------------------------------------------
Find the value of the expression
\begin{equation}
	e^{\sin(\pi/4)} - \log_{10}(25)
\end{equation}
Use \texttt{exp} for exponent function and \texttt{log10} for logarithm to
the base of 10.

\problem{Problem 4 (2 points)}
%---------------------------------------------------------------
Find the value of the expression
\begin{equation}
	\cos^2(\pi/3)
\end{equation}
Notice that human/mathematical notation is quite different from what Matlab
is expecting.

\problem{Problem 5 (4 points)}
%---------------------------------------------------------------
Find the largest number $x$ (one significant digit is enough) such that the
numerical evaluation of expression
\begin{equation}
	(1+x)-1
\end{equation}
equals to zero. The value of $x$ gives you an estimate of the relative
uncertainty of your calculations with Matlab, try to keep it in mind when
you do calculations. Note that $x$ is actually rather small. 

\problem{Problem 6 (4 points)}
%---------------------------------------------------------------
Find the value of the expression
\begin{equation}
	20/3-20\times(1/3)
\end{equation}
Algebraically you should get zero. If your result is not zero, please,  explain.

\problem{Problem 7 (3 points)}
%---------------------------------------------------------------
Find the numerical value of the expression
\begin{equation}
	10^{16} + 1 - 10^{16}	
\end{equation}
with Matlab.
Algebraically you should get 1. If your result is not 1, please,  explain.
