First Edition

For typos from the First Edition of the book, you will need to locate the Printing of your book. To do so, turn to the page in the front with the copyright (immediately preceding the dedication page). In the middle of this page, you will see a decreasing sequence of numbers, e.g.,

10 9 8 7 6 5 4 3 2

The last number that you see is the Printing of the book. In the above example, this is the Second Printing of the book. Scroll to the appropriate place below or click on the link to take you there.

Typos from Second and Third Printing

plot(x,y3,'c--')

The line

syms t

also needs to be inserted between the 4th and 5th lines.

implicitplot([eq2,eq3,eq4,eq5,eq6,eq7,eq8,eq9], x=...rest is okay);

The code will run fine with "{ }" but you cannot use the "color" option with it.

2x^5dy+(x^2y^4+1)ydx=0

eq1:=(x^2+1)*diff....(the rest is fine)

y=(-1/2)(cos(x)+sin(x)-5exp(x))

y=(-1/2)(cos(x)+sin(x)-5exp(x))

eq1:=eval(simplify(subs(eqyp, eqODE)));

int((1/f^2)*exp(int(-a1/a0)dx)dx)

That is, the f^2 in the denominator needs to be outside of the exponential. The c does not need to be there.

However, students often prefer to have "nicer looking" eigenvectors.

"Important note: we point out that the above method won't work for any arbitrary basis of eigenvectors but will always work for some basis of eigenvectors. That is, in certain situations we may not be able to get past step (a) and the problem is that we need to choose a different basis from which to start. Starting from a "good" basis allows the above algorithm to work and we mention the following: Remark 1 ..."

f(t-a), t "greater than or equal to" a.

0, t>5.

eq1=collect(eqODE)

The lines that calculate the c-values should all reference eq4 (not eq3). Thus the two sets of lines should be

c1=subs(eq4.c1)

c2=subs(eq4.c2)

c3=subs(eq4.c3)

ans1=nthroot(x^2+y^2,4);

(+/- x)/sqrt(ln(x)+C)

y(x)=(x-1+sqrt(3))^2

implicitplot([eq2,eq3,eq4,eq5,eq6,eq7,eq8,eq9], x=...rest is okay);

The code will run fine with "{ }" but you cannot use the "color" option with it.

eq1:=eval(simplify(subs(eqyp, eqODE)));
