Lecture | Topics/Sections | Some Standard Examples/Concepts |
---|---|---|
Day 1
March 27 |
2.3, 2.5 | Modeling: decay, mixing, cooling, growth. Physical models and the differential equations which result. |
Day 2
March 29 |
2.1, 2.2, 2.4 | Review derivation of solution to first order linear, and review separable equations. Mixing problems (equal rate in/out is separable; unequal rate is FOL) |
Day 3
April 1 |
5.1, 5.2 | Review series, Taylor series, and the radius of convergence. Series solutions to first order linear or second order constant coefficient. Solve y''+y'=0 via series, and isolate fundamental solutions as S(x) and C(x). Observe that sin(x) and cos(x) are also solutions. How are S(x) and C(x) related to sin(x) and cos(x)? Leads to representation of functions by series. |
Day 4
April 3 |
5.2 | Series solutions for the differential equations with nonconstant coefficients. Integral test for the positive series convergence and the p-series. |
Day 5
April 5 |
5.3 | More series solutions at the ordinary point. Alternating series and error estimates. |
