The student will have a short, one or two sentences, description of a problem that uses no calculus terminology.
- Stage 1: The student's first task is to ask the right questions in order to recast the problem in the language of the appropriate mathematics. It should also include a critique of old submissions on the topic if any.
- Stage 2: Then he is to explore the problem numerically and graphically with a spreadsheet (or other software) and make an approximation of what the answer might be and ask further questions.
- Stage 3: Finally, the problem is solved analytically, if possible, with the calculus tools and the answer is confirmed.
These are modelling problems and they can't be solved by manipulating formulas.
All the steps, the explanations of the methods, the data, the illustrations, and the computations are to be presented in writing. The methods should be based entirely on the material of the course (and common knowledge). The intended solutions aren't the kind that you can find on the internet. The project should contain your solution and not a discussion of a solution of somebody else.
The actual project statements are written as if by a person with no knowledge of calculus. That is why the problems may be poorly formulated, incomplete, and have many possible answers or none at all. As a result, the structure of the project might be much more complex than the three stages above.
Some projects have links to the actual students projects on the topic. If you pick one of those, you will have two choices: to use or not to use the previous work. In either case, why you accept or reject it is to be addressed in your essay. In the former case, you build your project on top of the old and in the latter you build from scratch. In either case, you should include a critique.
Project statements are below in the order of increasing complexity. All submissions are linked even the failed ones.
