The orbit of a planet is elliptical and can be described by the equation $ay^2 + bxy + cx + dy + e = x^2$ where \textit{x} and \textit{y} are Cartesian coordinates in the plane of the ellipse. Suppose the following set of observations of the planet's orbit are made \begin{tabular}{c|cccccccccc} \textit{x} & 1.02 & 0.95 & 0.87 & 0.77 & 0.67 & 0.56 & 0.44 & 0.30 & 0.16 & 0.01 \\ \hline \textit{y} & 0.39 & 0.32 & 0.27 & 0.22 & 0.18 & 0.15 & 0.13 & 0.12 & 0.13 & 0.15 \end{tabular} (c) Compute the condition number of the cross-product matrix of A using the spectral norm. To obtain the largest eigenvalue of a matrix, use the function \texttt{eigs} in MATLAB as in the previous assignment, and to compute the inverse of a matrix use the function \texttt{inv}. Compare your calculation with the condition number obtained with the \texttt{cond} function in MATLAB. Turn in both the code and the results. (1 point)

3. You are adding two sinusoidal transverse waves of the same amplitude. The first wave has a phase angle of zero, and the second has a phase angle of $\pi/4$. Sketch displacement vs. position of the two waves being added together as well as the resultant superposition of the two, labeling the amplitudes and phase angles. Plot these all on the same plot.
