Where is the Pinching/Squeeze theorem in Spivak Calculus? So I got Spivak Calculus 3. Edition. I'm starting it now but I want to know if there is the squeeze theorem clearly explained in the book, as I can't find it in the Appendix(pinching theorem, squeezing theorem, sandwich theorem, can't find any of these). Thanks

I don't have access to the third edition, but in the second one the squeeze theorem is an exercise in Chapter 5. The point (not explicitly made in the book) is that when you really understand the definition of limit (and Spivak puts a lot of work into this in that chapter), you don't really need the squeeze theorem as a theorem, but it is just a natural tool to be used.
