That would be a hard one. A book of appetizers without a main course. I read it when I was an undergrad wanting to get a broad sense of different areas in Math I could pursue.
If I had to pick one math book it would have to be a classic with some depth to it: Euclid’s Elements, Newton’s Principia, or Gauss’ Disquisitiones.
Yes, perhaps you're right! It could be frustrating, either because it doesn't give you enough to understand the introduction to an area, or because it doesn't give you any depth. I think it would be a bad mistake not to take a maths book with exercises and solutions to ones desert island.
