I havent written up notes on all the topics in my calculus courses, and some of these notes are incomplete they may contain just a few examples, with little exposition and few proofs. Functions and graphs, fourth edition gives students the essential strategies they need to make the transition to calculus. Many expressions in calculus are simpler in base e than in other bases like base 2 or base 10. However limits are very important inmathematics and cannot be ignored. Special limits e the natural base i the number e is the natural base in calculus. They are crucial for topics such as infmite series, improper integrals, and multi variable calculus. Throughout these courses, students will build a solid foundation in algebra, trigonometry, and mathematical theory.
