It doesn't count as practice unless you really DO it. What to Do Below is a list of things you are supposed to be able to do by the end of Stage 4. The links take you to short sets of practice problems. We recommend that you follow them all. Each practice problem has a button which will bring up a pop-up window with the answer in it.
Some answers also have a full calculation or further explanation in the window.
Feel free to discuss problems with your fellow students, be it in person, via email, over the telephone, or using a Hypernews group if one exists. Three hours should be enough time to complete the problems. Allow another hour for the Practice quizzes. For removable discontinuities, determine what value is needed to remove the discontinuity. Give examples of functions with given discontinuities.
