Errata for Mathematics for Physicists by Susan Lea
Page 60 There are sign errors in equations 1.82 and
1.83. They should be:
Page 62 There are sign errors in the equations for the
even mode and the odd mode. The correct equations are:
and
Page 111. Equation 2.48 is missing a minus sign. It should
be:
Page 138 In Example 2.21, 
should be
Page 142 Below Figure 2.31, there is a factor of 2 missing in the conversion of cosh kz to exponentials. This factor does not affect the argument.
Page 162 In problem 19, the potential is
and
on alternate quarters, not alternate halves. The last sentence
should read:
"Show that the result for the potential may be expressed ....."
Page 163 In problem 25,
the statement "at x = X0,
v =V0x" should be" on the x-axis at x = X0, v = -V0x".
Page 181 There is an error of a factor of 1/2 in the ex[ression for u' that continues into the final result Q1/2 which should be just Q1.
Page 206. In Table 3.5, $B$3 should be $B$2 throughout.
Page 234-7. The solution to Example 4.3 should contain
only odd n terms. A corrected version of the
example is available, that shows the resonant behavior for the
term.
Page 252. Half way down the page,
should be
In the last line, p >
0 should be p > -1.
Page 262/3. In Example 5.5, There is an "omega" missing from the argument of the cosine function.
Page 285. In Problem 21, fifth line of the table,
Np
Ac, Np should be Ra.
Page 306 In the middle of the page, I3 should be |I3|
Page 327. In Example 7.2, in the second equation, the
left hand side should have
.not
Page 365. In Step 1, the y-equation solutions should be functions of y not x .
Page 394.
not
so the expression for the potential is correct.
Page 402. In the expression for dJ/dnu, there is a missing factor
of 1/2nu. This factor does not affect the argument.
Page 424 In equation 8.128, the differential element
should be
Page 430 In problem 6, in the first line of the
answer for In l , (n-1)!! should be (n-l)!! (en minus el).
Page 434 In problem 30(a),
there is a missing factor of (-1)n in front of the Bessel function
in the summation.
Page 449 In the expression for A23,
the z bar in the denominator should be z.
Page 467 At the end of the first
paragraph beginning The rotation group, there is an
extra sentence "This group is Abelian." which should be deleted.
Page 461 Problem 10. The electric field must be both divergence free and curl free at the origin. This one is divergence-free but not curl free. Please change the components to:
Page 599 The reference for "Regular singular point" should be page 178 not 78

Page 7 In the fourth equation there is a factor of two
missing from the
term. It should be:
The rest of the solution is not affected, because this term drops out.
The next equation is missing the
It should be
