**Errata for An Introduction to the
Mathematics of Biology**

** With Computer Algebra Models.**

What follows are errors found as of September, 2000. It would be appreciated if additional errors are sent to Jim Herod or (send e-mail)

All the
syntax of the book in Maple V, release 3 can be found at this site.

All the
syntax of the book in Maple 6 can be found at this location. The code will also
run with Maple V, release 5.

iv, Yeargers address:

Change:
the School of Biology ZIP code should be 30332-0230

iv, mid-page: <br>

Change: 1. Shonkwiler, Ronald K., 1942 - .

to
read 1. Shonkwiler, Ronald W., 1942
- .

Page 8:
Second paragraph, next to last sentence:

Change
“preceeding” to “preceding”

Page
24: second line:

add a
parenthesis

>
pts:=[seq([Time[i],CAC[i]],i=1..24];

becomes

>
pts:=[seq([Time[i],CAC[i]],i=1..24)];

Page
37: four lines from the bottom

a
factor of exp(-t) is missing in the first term, so that

y(t) =
1/9 + C1 exp(2t) + C2 t exp(2t)

becomes

y(t) = exp(-t)/9
+ C1 exp(2t) + C2 t exp(2t)

and 46: Exercise 2

Use the
same differential equation in part (a) as in (b) and (c)

so that
the first line of the syntax for Exercise 2 (a) reads

>
dsolve({diff(y(t),t)+y(t)/5=sin(t),y(0)=0},y(t));

Add a
top line

In the
definition of death rate, change "n" to "t" in two places.

Page
229: The equation x(t)=-a x(t)+2 should read x’(t)=-a x(t)+2.

Page
230, line 9: The equation x(t)=-a x(t) should read x’(t)=-a x(t).

314: Exercise 2:

The figure
referenced 9.3.3 should be 9.6.2.

Page
314: Exercise 3:

Remove
the word "for" in the first line so that the line reads

"Draw
the graph of the solution c(t) in equation (9.3.2) with constants"

Page
348: Exercise 4:

the
line

plot(makelist(sol,1.3),makelist(sol,1.4),makelist(sol,1.5));

should
be changed to read

plot({makelist(sol,1.3),makelist(sol,1.4),makelist(sol,1.5)});
