Problem 4(a): Here is an example which shows how to interpret the Matlab output.
Problem 4(b), (c): Problem 5 of Problem Set A explains how to
make contour plots. Use t, T instead of
x, X and use in contour the formula in
T, Y resulting from (a) (remember to use
``.*'' instead of ``*'').
Problem 4(d): Write the problem in the form g(y)=0 where y is
the unknown function value at t=1. Define an inline function
g(y). Then use fzero(g,guess)
