  1. Approximate Solutions : why might we be interested in obtaining numerical solutions to differential equations?
    1. Euler's method : what are the steps referred to in Euler's method? if h=.1 and t0=1, what is t3? how are the values y1, y2, etc., calculated?
      1. error in the Euler method : what is true about the error in Euler's method?
    2. One-Step methods : what is a one-step method? why is it called this? what is the ``approximate slope function'' for Euler's method?
      1. error : what is the global error of a numerical method? how is the accuracy of one-step methods characterized?
