CS1371 Teaching Outlines Week 1 Philosophical Notes: 1. with a text book containing all the students should know, we are free to explain the difficult parts of a chapter, but expect the students to dig around for the rest of it. 2. Having said that, many of the chapters push just a bit further than the students really need to go, thereby challenging the top flight students. We might have to make clear which parts are “beyond the pale.” Homework 1 topic: Getting Started Homework 2 topic: Basic Vectors – so we must introduce vectors on Friday Monday January 8th, 2007 Objective: Introduce Matlab – Chs 1 & 2 Introductions  Show of hands by major  Show of hands by class year  Introduce yourself Course Overview  Slide presentation  Open class Web site  Point them to Syllabus page Concept: variables and assignment  Difference between algebraic = and assignment.  Encourage useful variable names Wednesday, January 10th, 2007 Objective: Scripts – Chapter 3 Problem Solving  Discuss Space Ship One (or some other problem type) – o X prize o Carried to 50,000 ft on mother ship o Rocket motor gives vertical velocity V o Outer space defined as above 100 km altitude o How would you calculate the required velocity? (v2 = u2 + 2 a s) o $15,000 for ride into outer space o If you had some velocity V1 (> V), how long would you get in outer space for your money? (s = u t + ½ a t2 ) -> quadratic equation Matlab Introduction  Enter some stuff into the Matlab Command Window.  Show the variables appearing in the Workspace.  Do the velocity problem o 1 km = 3281 ft o g = -9.81 m/sec2 Writing a Script  Talk about the Current Directory (I usually work from my Acme account)  Open the empty script provided in the Matlab editor  Demonstrate do-a-bit / test-a-bit strategy using the Debug/Save and Run menu item (F5) with the velocity and time above 100 km problems  Solve the quadratic equation in the script explicitly as shown in the finished solution
