Introduction to Cosmology
Instructor’s Manual
, 1
Introduction
The purpose of this instructor’s manual is primarily to provide worked
solutions for the end-of-chapter problems. In writing up the solutions, I didn’t
try to mimic the solutions that an A+ student will submit; instead, I tried to go
into “verbose” mode, giving general solutions that emphasize the physics
behind the problem. I also indulge in occasional asides, and recommendations
for further problems you can pose for your students. (The solutions were
written in some haste, so errors could lurk – let me know if you find any.)
In the worked solutions, I refer to equations both in the textbook
Introduction to Cosmology (2nd edition) and in this Instructor’s Manual. To
help keep things clear, when I refer to an equation in the textbook, I use the
format “Eq. 6.66”; when I refer to an equation in this Instructor’s Manual, I use
the format “equation (6.66)”.
In addition to worked solutions, I also give a brief summary of the changes
that I made in going from the first edition to the second edition. I also give
references for some of the assertions made in the text. (I didn’t want to clutter
up the text with references, but I assume that some of you will be curious
about the source of some of my less-obvious assertions.)
In writing the second edition, I took the opportunity to correct the
typographical errors present in the first edition of Introduction to Cosmology.
However, I am sure I introduced some new errors! If you find any, please let
me know at . Future versions of the Instructor’s Manual
will contain a list of errata.
