Solving Ordinary Differential Equations: ConcepTest and Example Problem

Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.

An example problem on using Euler's method to solve a differential equation.
Example Problem 1
Solve the two ordinary differential equations simultaneously using Polymath.
dCA/dt = -k1CA

dCB/dt = k1CA – k2CB2

Intial conditions: at t = 0, CA0 = 10, CB0 = 2
