The table below shows the drag coefficient cp of a sphere as a function of Reynold's number Re. 2000 | 20,000 Re 0.2 cp 103 13.9 2.72 | 0.800 0.401 | 0.433 2 20 200 (a) Use a natural cubic spline to find cp at Re = 5,50, 500, and 5000. Plot the experi- mental data and your interpolating spline. Hint: Use a log-log scale and the spline command. (b) Solve using a polynomial interpolant intersecting four nearest-neighbour data points (but do not use a log scale). Which is the better approach and why?

Consider the following 10 data points: X= {(2,0, 1, -3, -2), (0, 2, -3, -3,-2), (1,2,1,3,-2), (-1, 1, 3, 2,-1), (1, 0, 1,-1, 1), (2, 3,-1,1,-2), (-2,3,-3, 3, 2), (-2,-2,2,3,-2), (-2,-3, 1, -2, -3). (-3, 2, 0,-1,-2)}. Compute the unit length principle components of X and choose two of them for PCA, then calculate the projection of each data on these two principal components. You could use python or matlab to obtain eigenvectors and eigenvalues.
