SUMMARY
Page 42 of "Calculus" by Michael Spivak discusses rational functions but presents examples that are not polynomial functions. The expressions provided, p = x + x² + x.sin²x and q = x.sin x + x.sin²x, illustrate a broader class of functions that includes rational functions but are misinterpreted as such. The text clarifies that these examples serve to highlight the characteristics of rational functions without being classified as them. This distinction is crucial for understanding the context of the discussion.
