Due Date Assignment
Tue 8/22
* Though you will need to be have and know how to use a hand held graphing calculator (e.g. TI-84) for the AP exam, you will find the Demos Graphing Calculator which runs on computers, smart phones, and tablets, to be very useful. Start by trying it on a computer. You can save your work if you click sign-in in the upper left hand corner of the window.

Mon 8/28
* Consider what you learned your first week of your journey through Calculus. You should talk about amount functions, rate functions, locally linear, and our seven easy pieces of “nice” function curves. Your tasks are to create two documents that will help students learn about these concepts.

1. Building Rate Functions: Take a look at this mathlet - Building a Rate Function. The mathlet needs user guide:
— (a) a set of instructions how to use the buttons, boxes, etc.; and
— (b) a paragraph explaining how $$f'(x)$$ is defined and what $$f'(x)$$ means.
Be sure to explain and use the concepts of amount functions, rate functions, and locally linear.

2. Using Rate Functions: Make nice version of the Seven Easy Pieces table (see kwiki 20005 question 1) and write a paragraph describing what the table says.

TurnIn: in typed second drafts of your work for tasks 1 and 2. (You can handwrite parts that might be difficult for you to do with a computer.)
