Clifford Pickover's "Calculus and Pizza" is praised for its engaging style, though it diverges from traditional calculus texts by incorporating narrative elements and tangents unrelated to mathematics. Readers are advised that while it offers a unique perspective, it may not cover all standard calculus topics comprehensively. Recommendations for other accessible calculus books include "The Complete Idiot's Guide to Calculus" by Michael Kelly, noted for its humor and clarity, and "Calculus" by Larson, Hostetler, and Edwards, which includes proofs and problem-solving sections. The discussion also touches on the confusion surrounding course names in mathematics, particularly regarding the relationship between analysis and calculus, with some asserting that functional analysis can fit between Algebra II and calculus. Overall, the conversation highlights the importance of supplemental practice and varied resources for mastering calculus concepts.
