ICE: Matlab For

Given some positive number \(K\), write Matlab code to plot \[ \sum_{k=0}^K \frac1{2^k} \cos{k\pi x} \] on the interval \([-1,1]\). Note that this will mean first choosing some number \(N\) and making a vector \(x=(x_0,x_1,\dots,x_N)\) where \(x_0=-1, x_1=-1+1/N, x_2=-1+2/N,\dots,x_N=1\), and then evaluating the cosine functions over that vector and adding all those terms together.

The "final exam" for this course will take place at 8:00 AM on Tuesday, 12 December. This will be an ordinary 50 minute test. It will be comprehensive, but weighted toward the latter half of the semester. As always, paper notes will be permitted, but no electronic devices will be allowed.

A Solution example is available for the quiz.

Assignment A is posted.
