Physics in the Arts Lecture S9 Fourier Analysis crepuscular tome steve here now Exam 3 is coming up Sunday April 26 date review sessions before exam 3 Wednesday April 29 posted on the Canvas home page Attend 1 review session also listed in the syllabus time TA room assigned Monday Tuesday April 27 2 00pm 4 00pm Anderson at class time 2 25pm or 3 30 Miguel pm Sterling 1333 Chamberlin 2241 April 28 5 00pm 7 00pm Rox Sterling 1333 Read book chapters 10 13 14 15 16 17 look at pdf files for all lecture slides on Canvas If you feel the need for more practice problems you can do all the problems at the end of book chapters 10 13 14 15 16 17 When you are done with each problem look up the solution in Chapter 21 and or ask us during the reviews or the office hours All relevant formulae and numbers for Exam 3 are given to you as shown on page 1 of Exam 3 Therefore there is no need to memorize any of them but you do need to know what the formulae mean and how to use them Cheating includes looking at notes books websites cell phones not even as a calculator talking to anyone else about the exam content or something completely different It doesn t matter to us what you are talking about if you talk you get a zero If you engage with anyone else talking to you you get a zero Any of the above will be considered cheating We will watch you and also record you during the exam so if you are caught cheating in any of the above ways you will get a zero for Exam 3 Bring a calculator a pencil a ruler Exam 3 Wednesday April 29th 2026 at your usual class time Location Bascom Hall 272 at 2 25 pm Location Chamberlin Hall 2241 at 3 30 pm McBurney students will be given more time and will do their exam in the lab 3124 Chamberlin Hall See separate e mail There will be 3 questions each worth 30 or 35 points so the total grade is 0 100 Each of the 3 questions will be graded identically by 1 of the 3 TAs so all grades are fair Exam 3 will be based on strings pipes musical scale and Fourier analysis To prepare for Exam 3 Do practice problems then look up solutions All problems and solution files are posted on the Canvas home page Attend 1 review session also listed in the syllabus review
