- I’m out of town from this afternoon through Friday
- Tomorrow’s class is Prof. Macula on differential equation example(s)
- Section 7.4
- Examples of kinds of differential equation, or different applications
- Half-life = ln2 / k
- Examples: chemical reaction rates
- Reactant concentration decreases with time
- Concentration of reactant A = [A]
- Reaction rate = d[A]/dt
- 0th order
- 1st order: d[A]/dt = -k [A]
- 2nd order: d[A]/dt = -k [A]2
- Reactant concentration decreases with time
- First-order differential equations
- Read
- “General First-Order Differential Equations and Solutions” part of Section 9.1 (bottom of page 524 through top half of 526)
- Section 9.2
