Learning objectives

• Master linear functions of 2 variables
• Explore representations of functions of 2 variables by graphs, tables, and contour diagrams using Mathematica

Before class

• Read Hughes-Hallett sections 12.1-4. 
• Ponder Hughes-Hallett problems 12.1: 1, 15, 23, 24, 29, 30; 12.2: 1, 2, 14, 23, 27; 12.3: 7, 15, 16, 17, 18, 22, 29; 12.4: 1–8, 16, 22, 24.
• Complete HW1 on WeBWork
• Download Mathematica onto your laptop (so we can use it in class)
• Post to Piazza

In class

• Examine a few contour diagrams in real life.  For homework, find a link to another online contour diagram that you like, and post it on Piazza, with a brief description of the function and variables.
• Work selected problems
• Activity: visually representing 2-variable functions with Mathematica
