First of all, the due date for this post is March 22, which happens to be the date for the test. Coincidence? NOT! Anyone who seriously plans to do this should get cracking!
Your post must have two parts to it:
Part 1:
- Design your own ferris wheel, specifying its size, location of centre (relative to a wall and the ground), rotation speed, exactly where people get on, & how many spins each customer gets. Note that all of those values must be different from those that were used in our ferris wheel in class.
- Show the graph for either distance from wall, or height above ground, as a function of time, for their entire ride. Give 2 different rules (one using sin and the other using cos) that could represent your graph.
What I’ll be looking for, apart from the above:
- proper vocabulary and notation
- a complete description of your ferris wheel, in English, including which quantity you are depicting on the graph (distance from wall or height – don’t make me guess which one)
- a ferris wheel that could conceivably exist (ie it doesn’t go underground or behind walls)
- a graph that fits that description, with clearly labelled axes
- two rules that both fit your graph
- validation of your graph and your rules
Part 2:
Solve a problem by modeling it as a trig function:
- Pick any of the 4 problems posted at sakai
- Include in your work, the rule for the situation, with defined variables
- Include a graph representing the situation, with all axes labelled
- Include your solution to the questions
What I’ll be looking for, apart from the above:
- all steps shown and explained
- well-organized work that is easy to follow
- validation of your rule, your graph, and your solutions
- correct rule, graph, and solutions
Bonus points available in both sections for anything extra, like exceptionally cool graphics, or use of a web tool to embed something into your post (eg codecogs, scribd, vimeo), or just plain personality and pizazz!
