The scope and treatment of Dr Maxwell's two-volume course covering the transition from school to university is directed towards training students in algebraic thinking, so that processes do not become too mechanical. The explanations are full, the difficulties of the beginner are foreseen and overcome. Indeed, the course should prove excellent for the lone student as well as for the supervised class. Topics in part one include polynomial theory, equations, inequalities, partial fractions, permutations and combinations, the binomial theorem and series and determinants. The 'feel' of the book may be illustrated by reference to the treatment of partial fractions, which is novel in several ways. A theoretical exposition is given in some detail and varies from standard treatments in leading to a method of calculation that arises directly from it. The book contains many 'drill' examples, which the author considers essential.
Calculus: A Comprehensive Introduction Author: Dr. Eleanor Vance Publisher: Stellar Academic Press Edition: Third Revised Edition ISBN: 978-1-5678-9012-3 Book Description Calculus: A Comprehensive Introduction stands as a definitive text designed to guide undergraduate students through the rigorous yet ultimately rewarding landscape of single-variable and introductory multi-variable calculus. Spanning over a thousand pages of meticulously developed theory, detailed examples, and challenging problems, this volume is structured to build deep conceptual understanding alongside robust computational proficiency. The book is meticulously organized into four major parts, mirroring the traditional progression of a standard calculus sequence, yet offering far greater depth and historical context than typical introductory materials. Part I: Foundations of Change – Limits and Continuity This initial section lays the indispensable groundwork upon which all subsequent calculus is built. It moves deliberately beyond mere computational rules to explore the fundamental concepts that define the calculus revolution. We begin with a careful examination of the real number system, emphasizing the completeness axiom, which is crucial for a rigorous understanding of limits. The concept of a function is introduced comprehensively, detailing domain, range, graphical representations, and various classes of functions—polynomials, rational, trigonometric, exponential, and logarithmic. The core of Part I resides in the formal definition of the limit ($epsilon-delta$ definition), presented not as an abstract hurdle, but as the precise language needed to discuss instantaneous behavior. Numerous worked examples illustrate how to construct rigorous proofs for the existence and non-existence of limits. Special attention is paid to one-sided limits, limits involving infinity, and asymptotic behavior. The concept of continuity is developed directly from the notion of the limit. We investigate various types of discontinuity (removable, jump, essential) and then proceed to establish the fundamental theorems of continuous functions on closed intervals, most notably the Intermediate Value Theorem (IVT). The rigorous proof of the IVT is provided, emphasizing its crucial role in establishing the existence of roots and solutions in applied problems. Part II: The Differential Calculus – Rates of Change Part II transitions seamlessly into the concept of the derivative, motivated by both the geometric problem of finding the tangent line and the physical problem of determining instantaneous velocity. The definition of the derivative as a limit is explored thoroughly before introducing the powerful rules of differentiation. This section features an exhaustive treatment of differentiation techniques. Standard rules (product, quotient, chain rule) are derived, and their application to algebraic, trigonometric, inverse trigonometric, exponential, and logarithmic functions is covered in depth. Special focus is given to implicit differentiation and its role in problems where variables are intrinsically linked. A significant portion of this part is devoted to the applications of the derivative. Kinematics (velocity, acceleration, jerk) is reviewed, followed by a thorough exploration of related rates problems, requiring students to model dynamic situations accurately. Optimization problems, ranging from classical geometry puzzles to real-world business scenarios (maximizing profit, minimizing cost), are presented with a systematic problem-solving methodology. The central theorems of differential calculus are proven rigorously: Rolle's Theorem, the Mean Value Theorem (MVT), and the Increasing/Decreasing Function Test. The relationship between the sign of the first derivative and the monotonicity of a function is solidified. Furthermore, we introduce the concepts of concavity, inflection points, and the Second Derivative Test for classifying local extrema. Curve sketching is elevated from a simple exercise to a systematic analysis utilizing all available derivative information. L’Hôpital’s Rule is introduced as a powerful tool for resolving indeterminate forms arising from limits related to derivatives. Part III: The Integral Calculus – Accumulation Part III pivots to the concept of accumulation, addressing the second fundamental problem of calculus: finding the area under a curve. This development moves from the intuitive concept of approximating areas with rectangles (Riemann sums) to the formal definition of the definite integral. Detailed historical notes illuminate the contributions of Newton and Leibniz. The theoretical foundation is established through an in-depth analysis of Riemann sums, including left, right, midpoint, trapezoidal, and Simpson’s rules, with error bounds provided for each approximation technique. The integrability of various classes of functions is discussed. The cornerstone of this section is the Fundamental Theorem of Calculus (FTC). Both Parts 1 and 2 of the FTC are presented, rigorously proved, and repeatedly emphasized as the bridge connecting differentiation and integration. Techniques for evaluating definite and indefinite integrals receive comprehensive coverage. The methodology for finding antiderivatives is explored extensively, starting with basic integration formulas and progressing through substitution (u-substitution) for both definite and indefinite integrals. The applications of integration are broad and multifaceted, including calculations of area between curves, volumes of solids of revolution (disk, washer, and shell methods), arc length, and surface area of revolution. Work and fluid force problems are also included to illustrate the power of integration in physics and engineering contexts. Part IV: Techniques of Integration and Introduction to Sequences and Series This final section addresses the complexities encountered when integrating non-elementary functions and offers a crucial introduction to the mathematics of infinite processes. Techniques for integration beyond simple substitution are developed systematically: Integration by Parts (derived from the product rule), trigonometric substitutions (for integrals involving $sqrt{a^2-x^2}$, etc.), and partial fraction decomposition for integrating rational functions. A dedicated chapter covers improper integrals, examining convergence and divergence in scenarios involving infinite limits of integration or infinite discontinuities within the interval. The transition to infinite processes begins with an introduction to sequences, defining convergence rigorously using epsilon notation. This smoothly leads into the study of infinite series. Students are introduced to the geometric series and the concept of convergence. A broad array of convergence tests is developed and practiced: the n-th Term Test for Divergence, Integral Test, Comparison Tests (Direct and Limit), Ratio and Root Tests, and the Alternating Series Test. Conditional and absolute convergence are clearly distinguished. Finally, power series representations are introduced, focusing on Taylor and Maclaurin series. Derivations of these series from known functions (like the geometric series) are performed, and their radius and interval of convergence are determined. The utility of these series for approximating functions and evaluating otherwise intractable definite integrals is demonstrated, providing a strong foundation for subsequent study in Differential Equations or Advanced Analysis. Target Audience: Undergraduate students in STEM fields, including Mathematics, Physics, Engineering, Computer Science, and Economics, requiring a rigorous, proof-oriented yet application-rich treatment of Calculus I and Calculus II concepts. Prerequisites: A strong foundation in pre-calculus mathematics, including trigonometry and analytic geometry. Pedagogical Features: Rigorous Proofs: Essential theorems are accompanied by detailed, accessible proofs suitable for developing mathematical maturity. Historical Notes: Contextual interludes illustrating the development of key concepts by historical figures. Chapter Review Sections: Extensive lists of review questions categorized by concept and application. Computational Exercises: Hundreds of drill problems focusing on technique mastery. Conceptual Exercises: Challenging problems designed to test deep understanding of underlying principles rather than rote calculation. Annotated Examples: Step-by-step worked examples that explicitly state the justification for each step taken.
