Ray D'Inverno: Introducing Einstein's Relativity

Here are my solutions to various problems in Ray D'Inverno’s textbook Introducing Einstein's Relativity. The book does give answers to most problems at the back, but it doesn't provide the working behind them in most cases, so I'll post my own modest attempts here.

After some consideration, I've decided to repost this index to the solutions. I understand that some folks may be concerned that I am providing 'free' answers to problems that some students have been assigned as homework, but there are several points that should be made:

Chapter 2 - The k-calculus

2.2, 2.3, 2.4, 2.52.6

Chapter 5 - Tensor algebra

5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 5.10, 5.11, 5.12, 5.13, 5.14, 5.155.16 (i-iv), 5.16 (v)

Chapter 6 - Tensor calculus

6.1, 6.2, 6.3, 6.46.5, 6.6, 6.7, 6.8, 6.9, 6.10, 6.11
