Hints and Tips

  1. Start early, when each set opens.
  2. Do the example homework set, Chap0 or homework0, or similar. It's easy & will help you with the homework system.
  3. Don't submit partial answers. You have six submissions per problem.
  4. Work the problems out by hand before entering them in the system. You can get a hardcopy of a problem set from the problem listing page of a problem set.
  5. Preview your answers before submitting them.
  6. Use calculator syntax:
    1. Carefully parenthesize. Type cos(2pi), e^(-ln(3)), or 1/(1+x), not cos 2pi, e^-ln3 or 1/1+x. Note that sin2x is read as sin(2)*x, which is probably not what you want. Enter sin(2x) instead.
    2. The square root is sqrt(x) or x^(1/2).
  7. Watch your case: X is different from x, Sin is different from sin, and Pi is different from pi. You want pi.
  8. Watch your precision. The system generally requires that numeric answers be correct at least four or five significant figures in an answer before it.
