18. Consider the initial value problem = y -t, y(0) = 1 (See also exercise 5). dt a) Using the modified Euler method fill in the estimate obtained for y(3) using the number of subintervals specified in the table below. The y value should be written to the fourth decimal place. # of subintervals 100 200 400 800 y(3) b) Based on the table obtained in a), what is the smallest number of subintervals you should use to produce an approximation that has three decimal place accuracy throughout the interval [0,3]? c) Using the number of subintervals determined in b) (and the modified Euler method) use the graph of the solution y(t) to estimate a value t, in [0,3] such that y(t,) = 0. (Such a value is called a root of the solution.) Type the estimate in the comments box provided in ode.xls.
