# Administrative Information - **Class Meeting**: Friday, September 18, 2026, 1:00–1:50pm — **Coolbaugh 212** - Previous meeting: [[MATH310F26(Day 9) - The rectangular pulse]] - 📄 [[Teaching/MATH310/MATH310F26/Administration/MATH310_F26_Syllabus_1.0.pdf|MATH 310 F26 Syllabus, v1.0]] > [!info]- Admin. Notes > Expect an LR and WB for each lecture. WBs target 15-minute engagements (longer early on); LRs are short, ~5 minutes. > > - 🎯 **[LR] [Day 9 Reflection Questions](https://elearning.mines.edu/courses/81632/quizzes/121253)** — 4 questions drawn from Monday's material, unlimited attempts, highest kept — due **Tuesday 9/16, 11:59pm** > - 🎯 **[LR] [Day 9 Reflection Statement](https://elearning.mines.edu/courses/81632/quizzes/121254)** — one free response, no wrong answers — due **Tuesday 9/16, 11:59pm** > - 🎯 **[WB] [Workbook 6](https://elearning.mines.edu/courses/81632/assignments/586618)** · [[MATH310F26_WB6.pdf|blank]] · [[MATH310F26(Workbook 6 Companion) - What a conjugate pair extracts|companion]] > - 🎯 **[WB] [Workbook 7](https://elearning.mines.edu/courses/81632/assignments/586619)** · [[MATH310F26_WB7.pdf|blank]] · [[MATH310F26(Workbook 7 Companion) - Two tones and a constant, transformed|companion]] > - Another **modeling Q&A** lands this week — goal: direction by end of next week > - Meanwhile: the [[Fourier Series]] and [[Fourier Transforms]] applet pages are live — an assignment built on them is coming > [!example]- 🗃️ COMAP Corner — three from the archive > Three from the archive — one data, one computational, one weird — for a day of listening: > > - **Data/stats — Searching for a Lost Plane (2015 MCM B).** Inspired by MH370: a plane goes down in open ocean with no emergency signal. Build a search strategy that weighs sensor capabilities and generalizes across oceans and routes — probability doing rescue work. 📄 [[2015_MCM_Problem_A_Eradicating_Ebola_Problem_B_Searching_for_a_lost_plane.html|problem page (archive)]] · [comap.com](https://www.contest.comap.com/undergraduate/contests/mcm/contests/2015/problems/) > - **Computational — Repeater Coordination (2011 MCM B).** VHF repeaters extend low-power radios but interfere unless separated in space or frequency. How few repeaters serve 1,000 simultaneous users in a 40-mile radius — and what breaks at 10,000? Spectrum as a scarce resource. 📄 [[2011_MCM_Problem_A_Snowboard_Course_Problem_B_Repeater_Coordination.html|problem page (archive)]] · [comap.com](https://www.contest.comap.com/undergraduate/contests/mcm/contests/2011/problems/) > - **Just weird — The Drug Runner Problem (1988 MCM A).** Two shore listening posts catch one brief radio signal from a boat waiting offshore, each bearing good to only 2°. Bound where the boat can be, then design the helicopter's search pattern — 1988's idea of signals intelligence. 📄 [[1988_MCM_Problem_A_The_Drug_Runner_Problem.pdf|problem PDF]] · [comap.com](https://www.contest.comap.com/undergraduate/contests/matrix/PDF/1988/1988A.pdf) > [!warning] Skeleton — this is the pre-class page > Day 10 has not met yet (title provisional). Promised Monday: today we **hear** the Fourier transform — the audio side of the applet pages. The transcript and any captures fill in after Friday's class.
