2 involve actual solutions.

When studying for the exam, please be sure you acquire the following skills:

  • Know all definitions, terminology, etc. from chapter 1. There are no direct questions on this, but it is obviously necessary to know it.
  • Solve 1st order linear equation *) y' + p(t)y = q(t) and the I.V.P. resulting when the IC y(t0) = y0 is added to *)
  • Solve Bernoulli equations by reducing them to linear form
  • Solve separable DE M(x)dx - N(y)dy = 0 and related IVPs
  • Solve tank or mixing problems
  • Solve problems involving Newton"s law of cooling or heating
  • Solve radioactive decay and half-life problems
  • Set up and solve problems involving thrown or dropped balls in simple vertical motion, both in a vacuum and in a viscous medium like air
  • Know the form and solution of the logistic equation y' = r(1 + y/K)y, and the significance of r and K.
  • Solve exact equations and IVPs.
  • Do several iterations of Euler's method in a specific case to approximate solutions, and check the results agaiunst an exact solution
