Depends on how many decimal points of accuracy you want, and which functions. :) I have these books on my shelf, as they were part of every mechanical engineer’s tools of the trade decades ago. Once the slide rule was superceded by the electronic calculator there was no more need for books of tables.
However...Let's be honest. **Books** of tables are not necessary. A few pages of trig and log functions is enough for any high schooler and a few pages is not a “book”.
