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 problems 12.1: 1, 47; 12.2: 1,2; 12.3: 1, 5.
• Download Mathematica onto your laptop (so we can use it in class).
• Remember to bring your laptop to class (if you have one).

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 the Moodle assignment, with a brief description of the function and variables.
• Work problems
• Work selected problems
• Activity: visually representing 2-variable functions with Mathematica
• Log on to WeBWork and answer a question.
