Errata in instructor's materials sorted by date posted. Last updated 11/27-13.
A computer glitch inserted into some of the equations in the Instructor's Manual the meaningless numbers '80' and '1.80'. I have tried to remove all of them, but I may have missed some. Please be aware of the possibility of the existence of stray '80' and '1.80'. Please tell me if you find any and I will remove them. Thanks.
