Problems are from Blanchard, Devaney, and Hall, 2nd ed., unless otherwise noted.
[5.4] 2. Parts (b) and (c).
Keep the "essay" to just a few sentences!
[6.1] Laplace transform
8. (Inverse Laplace transform.)
14. (Harder inversion: pre-manipulation of Y will be helpful.)
20. (1st-order ODE IVP.)
[6.2] 14. Hint: recast term with Heaviside function in the form
ua(t) f(t-a).
Also: plot your solution with Maple for t in [0,10].
