                        Hand in 10/12: the curves y=4x(1-x)
                        and  y=sin(pix) both define arches
                        from (0,0) to (1,0) passing through (1/2,1). Which
                        arch is longer? Use your calculators to estimate
                        the two lengths. Is there a way to settle the
                        question without calculating the lengths?

                        converges when x=0.

                        and the first 5 terms of the power series for
                        sin(x), and compare with the graph of sin(x).

Nov  2    8.11          1,41,47
                        Review for Midterm
                        Hand in 11/9: Use power series to solve the
                        d.e. y'' = y2 with y(0) = 1, y'(0)=0.
                        Calculate the coefficients a0,...,a6.
   Friday November 6: Midterm II, part 1 (in class). 
   This part will cover methods of integration (7.1 7.2 7.3) and
   numerical calculation of integrals, with error estimates (4.9).
    
                        
Nov  9    Note: this week there will be two lectures on
          Monday (the second during recitation time)
          4.2           1,5,17,31,33,35,39,47,49
          6.11          1,3,7,9, 19,35, 47, 49,51,55
   Friday November 13: Midterm II, part 2 (in class). 
   This part will cover sequences and series (8.1 through 8.10). One
   20-point question will be: give the correct definition of this statement: 
   "The limit of the sequence a1,a2,a3,... is L." 

Nov 16	  6.12          1,3,11-14,15
          A3            1,3,7,11,19,23,25,27
          Hand in: Consider the differential equation y' = sin(x+y).
          1. Sketch the slope field for -2 < x < 6, -3 < y < 3. (Note that
          slopes are constant along the lines x + y = C; use this fact for 
          C = 0, pi/2, pi, etc. to make the job easier.)
          2. Let y=f(x) be the solution with initial value y(0)=0. Use your 
          slope field to sketch f and to estimate the first x > 0 
          with f(x)=0.
          3. Use your Euler's method program to check the accuracy of your
          estimate, and then to calculate x with 2 decimal places of accuracy.
          Run the program with small n to get near the right x, and then 
          increase n to get a more accurate answer.
