Learning Outcomes
On completion of this course, the student will be able to:
 State in precise terms key concepts relating to Fourier analysis and probability & statistics.
 Master the derivations of a set of important results in Fourier analysis and probability & statistics.
 Apply standard methods of Fourier analysis and probability & statistics to solve unseen problems of moderate complexity.
 Understand how to take a physical problem stated in nonmathematical terms and express it in a way suitable for applying the tools of this course.
 Be able to think critically about the results of solving such problems: whether they make sense physically, and whether different mathematical approaches are equivalent.
