- Review Session tomorrow, Fraser 213, 1:00 - 2:30
- Extra hours for math learning center
- Open 9:30 weekday mornings
- Final
- Monday, May 11, noon
- Comprehensive, but emphasizing material since 2nd hour exam (e.g., parametric equations, polar coordinates)
- Designed for 2 hours, you have 3+
- Format and rules otherwise similar to hour exams
- Donuts and cider
- SOFIs
- 5 responses so far
- Useful to me in improving courses
- Fill them out via http://go.geneseo.edu/sofi_survey
- Section 11.5
- Approximate areas with “circular fans”?
- Analogous to approximating areas in Cartesian (rectangular) coordinate system with rectangles
- Analogous to approximating areas in Cartesian (rectangular) coordinate system with rectangles
- Length formula
- Approximate areas with “circular fans”?
- Examples
- r = cos 2Θ
- Area in one lobe?
- Length of edge of one lobe?
- Integral is fairly easy to set up, but hard to integrate
- Good example of practical integration today: need to know how to model something as an integral, but calculators can evaluate the result
- (Remember those numeric integration methods back in February)
- Doing this in R says lengths is about 2.42 units
- Area in one lobe?
- Length of r = Θ2 between Θ = 0 and Θ = √5 (book exercise 21)
- r = cos 2Θ
