4. Find the natural spline that passes through the points {(xk , f(xk))} 3k=0, on the graph of f(x) = x + 2/x, using the nodes x0=1/2, x1=1, x2=3/2, x3=2. Check the accuracy of your interpolant at the value x = 3/4. Check it again at the value x = 7/4.

Assignment 4

Due: July 25, 2003 at class time

1. Problem 21.12 a,b, and e page 611.

2. Problem 22.1, page 631.

a) analytically (done for you in class if you were there)

b) graph the solution on the interval [0, 2]

c) generate estimates of the solution using Euler's method with h = .5 and h = .25

d) generate estimates of the solution using Heun's method with h = .5

e) generate estimates of the solution using Midpoint method with h = .5

f) compare the results of all these estimations at the point x = 1 using the true value of the solution at that point to compute true relative error values.
