typo: example 1.4.8 missing parentheses

typo: Exercise 1.4.4 part 2 should read “Show that is a solution to the IVP.”

typo: Figure 1.5.1 is missing…

typo: The differential equation in Example 2.2.3 should be

$\displaystyle \frac{dy}{dt} = \cos(t) – 7y$

typo: Example 2.2.3 dy/dt = cos(t) – 7y

Typo. eq 3.0.1 $\frac{dy_n}{dt}$ should be the last entry for the list, and the rhs equations should go from $f_1$ to $f_n$ as well.

typo. pg 84 at the end, there’s a reference to example 3.2.1 but the text just has ?? instead of the reference.

Typo. Exercise 3.2.5 is missing a close parenthesis on dx/dt =

“Furthermore, as in the case of the example considered here, solutions

may not “directly” approach an equiloibrium point, but may twist and turn

in state space.” pg 89. equilibrium misspelled.
