In each of Problems 9 and 10, use Euler's method to find approximate
values of the solution of the given initial value problem at t = 0.5,

Na. Use Euler's method with h = 0.1 to obtain approximate
values of the solution at t = 1.2, 1.4, 1.6, and 1.8.
N b. Repeat part a with h = 0.05.
c. Compare the results of parts a and b. Note that they are
reasonably close for t = 1.2, 1.4, and 1.6 but are quite different
for t= 1.8. Also note (from the differential equation) that
the line tangent to the solution is parallel to the y-axis when
y = ±2/√√3 ±1.155. Explain how this might cause such
a difference in the calculated values.

solution of this problem for 0 < t < 1. What is your best estimate
of the value of the solution at t = 0.8? At t = 1? Are your results
consistent with the direction field in Problem 8?
