    9 March Some code for today’s lecture

    u[t_, x_] := 
     Sum[(8/((2 k + 1)^2 Pi^2)) Cos[(2 k + 1)*.5*Pi*x]*
       Cos[(2 k + 1)*.5*Pi*t], {k, 0, 5}]
    u0[t_, x_] := (8/((2*0 + 1)^2 Pi^2)) Cos[(2*0 + 1)*.5*Pi*x]*
      Cos[(2*0 + 1)*.5*Pi*t]
    u1[t_, x_] := (8/((2*1 + 1)^2 Pi^2)) Cos[(2*1 + 1)*.5*Pi*x]*
      Cos[(2*1 + 1)*.5*Pi*t]
    u2[t_, x_] := (8/((2*2 + 1)^2 Pi^2)) Cos[(2*2 + 1)*.5*Pi*x]*
      Cos[(2*2 + 1)*.5*Pi*t]
    u3[t_, x_] := (8/((2*3 + 1)^2 Pi^2)) Cos[(2*3 + 1)*.5*Pi*x]*
      Cos[(2*3 + 1)*.5*Pi*t]
    Manipulate[
     Plot[{u[t, x], u0[t, x], u1[t, x]}, {x, -1, 1}, PlotRange -> 1], {t, 
      0, 12}]
    
    13 March Corrections to Exam 1 are due before Spring Break: You are to re-do Problem 1(C), explaining our eigen-procedure for the wave equation. If you opted not to do Problem 2(B), then you should do that problem at some point as well; you don’t need to submit Problem 2.
    13 March Exercise 3.2.4, along with the rest of section 3.2, should also be completed before Spring Break.
    13 March Here are the exercises for Section 3.3 and Section 3.4. These are due the week after Spring Break. But you should start them now!
