Errata David J. Griffiths, "Introduction to Electrodynamics"
- see author's list
- p. 21, Product rules are in a different order than in front cover. (not an error)
- p. 40, Warning: last equation on page (da₂) is only valid at theta=pi/2 since it is missing cos(theta). [Tom Pace]
- p. 115, Prob. 2.2 This theorem only holds in regions free of charge. Consider, for instance, the inside of a sphere of uniform negative surface charge.
- p. 151, Prob. 3.29 You need to expand to order (d/r)^4 to get the octupole term.
- p. 198, Prob. 4.34 Answer: p/epsilon should be replaced with 3 p/epsilon_0 (1+2 epsilon_r)
David J. Griffiths, "Instructor's Solution Manual"
- prob 48: integral should be from r=0 to R, not to infinitiy. [Tom Pace]
