      Read 7.3
      7.3; 3, 4, 15, 36, 38, 41.  p. 420; 53.  Problem A below.
      On 4b, you may want to sketch y=f(x) and the rectangles to understand the integral; these are left endpoints, so it is not obvious.
      On 36, further instructions are in the paragraph above.
      p. 420 (Chapter Review): 53.
      Problem A:  Estimate the integral of sin(x^2) from 0 to 2 using
      (a): n=4 intervals and right endpoints; by hand except for simple decimal calculations.  (Three decimal places will suffice.)
      (b): integral approximation website below with Midpoints and n=10, 20, and 100.  Report six decimal places.
