This course covers the theory of the Lebesgue theory of integration in d-dimensional Euclidean space, and offers a brief introduction to the theory of Hilbert spaces. Closely related topics in real variables, such as functions of bounded variation, the Riemann-Stieltjes integral, Fubini's theorem, Lp classes, and various results about differentiation are examined in detail. applications are basic facts about convolution operators and Fourier series, including results for the conjugate function and the Hardy-Littlewood maximal function.

Students enjoyed learning about different areas of mechanical engineering from experts in the field. They also liked learning to use MATLAB, which would be useful for future courses. Students said some of the lectures were boring and some of the material was too easy. They also said the lecture topics were disjointed from class to class. Students suggested doing more MATLAB demonstrations in class and covering more advanced material. This course may be useful to students who are unsure of whether they want to study mechanical engineering. While the MATLAB component may be chal enging, the course is overall not difficult, as it doesn’t cover the material in much depth.

Students praised this course for covering an interesting subject matter and for having a clear and knowledgeable instructor. Issues with the course included some students complaining the course wasn’t very interesting and that the lecture essential y restated what was written in the textbook. Suggestions for improvement included a desire for better feedback on homework. Prospective students should know that prior knowledge of undergraduate level math topics such as analysis, linear algebra, and other topics was helpful. Textbook exercises and homework were found to be chal enging as wel .

Students broadly praised this course’s instructor for being thorough and effective in leading this course that covered chal enging subject matter. Students’ issues with the course varied widely; one student felt that grading in the course was inconsistent as it started off being fairly light and got much harder later on, while another student thought there were a lot of proofs to learn. Suggestions for improvement varied widely though a couple students thought the course could be improved if grading was more 220consistent. Prospective students should know that students found that the workload was fairly reasonable for a course at this level. However students also found it important to make sure to keep up with the coursework in order to be successful in the course. 221
