- GREAT Day
- Tuesday (Apr. 21)
- No class!
- Extra credit similar to colloquia for summary/reaction to any one math talk or poster
- Colloquium
- Monday, April 20, 3:30 - 4:30
- Faculty candidate, Sylvia Saccon
- Extra credit
- Exam 2
- Tomorrow (Thursday, April 16)
- Material since 1st exam (e.g., differential equations, sequences, series)
- Rules and format similar to 1st exam
- First-order linear differential equations
- Equations of the form dy/dx + P(x)y = Q(x)
- Solvable via “integrating factor” v(x)
- To solve:
- Integrate P(x) and exponentiate to get v(x)
- Integrate v(x)Q(x)
- Divide by v(x) to get y
- Book sections on test
- 7.4 (separable differential equations)
- 9.1 - 9.2 (1st-order linear differential equations)
- 10.1 - 10.8 (sequences and series)
- Problem set question re how many terms to evaluate for given error
- Key idea: use error formula for alternating series to set up inequality to solve
- Key idea: use error formula for alternating series to set up inequality to solve
- (Wednesday, April 22)
- Parametric curves
- Read section 11.1 (“Parameterizations of Plane Curves”)
