Quiz Information
Math 385, Section B1, Fall
2006
Quiz #1: You should be able to sketch the
direction field for the first order differential equation y'=ky, both when
k>0 and when k<0. You should also be able to find the general solution of
this equation (that is, show that every solution has the form y=Cekx
for some constant C).
Quiz #2 (Wed. Sept. 27): This will be a substitution
problem, based on Section 1.6 methods. It might be a type of substitution you
have seen before (Bernoulli, homogeneous), or it might be new, requiring you to
make a reasonable guess, like problem 29 from 1.6.
Quiz #3 (Wed. Oct. 23): You will be asked to solve a
linear, homogeneous, constant coefficient differential equation, either with or
without initial conditions. Problems 1-26 in Section 3.3 are all examples of
this type of problem.
Quiz #4 (Wed. Nov. 29): Find the Fourier series of a given function
(see Sections 9.1 and 9.2).
Quiz #5 (Wed. Dec. 6): An undetermined coefficients
problem (review problem!). See Section
3.5.
