2.1 The Tangent and Velocity Problems
In this video, you’ll be introduced to two of the fundamental problems that led to the development of calculus: the tangent problem and the velocity problem. We’ll explore what each problem is asking, why it matters, and how these ideas connect to the concept of limits — the foundation of differential calculus.
2.2 The Limit of a Function
In this video, you’ll learn the foundational concept of limits — the building block of calculus. We’ll cover intuitive and formal definitions, explore one-sided limits, and discuss infinite limits and asymptotes. Through examples, you’ll see how limits describe the behavior of functions near a point, even when the function value at that point may not be defined.
2.3 Calculating Limits Using the Limit Laws
In this video, you’ll discover how to evaluate limits efficiently by applying fundamental limit laws. We’ll also cover strategies for handling indeterminate forms and introduce the squeeze theorem, a powerful tool for solving tricky limits. With worked-out examples, you’ll see how these techniques build the foundation for more advanced topics in calculus.
2.4 The Precise Definition of a Limit
In this video, you’ll explore the epsilon–delta definition of a limit, the rigorous foundation behind calculus. We’ll discuss why an informal idea of “getting close” isn’t enough, then carefully build the precise definition step by step. You’ll also see how to use graphs to find δ for a given ε and how to prove a limit statement formally with worked-out examples.
2.5 Continuity
In this video, you’ll explore one of the most important ideas in calculus—continuity. We’ll define what it means for a function to be continuous at a point, look at continuity on an interval, and discuss different types of discontinuities with clear examples. Finally, we’ll see how the Intermediate Value Theorem applies when working with continuous functions.
2.6 Limits at Infinity; Horizontal Asymptotes
In this video, you’ll explore how functions behave as x grows larger and larger (positively or negatively) without bound. We’ll define what a limit at infinity means, work through examples, and see how these limits reveal horizontal asymptotes. You’ll also learn algebraic strategies for handling indeterminate forms like ∞/∞ and ∞ – ∞.
2.7 Derivatives and Rates of Change
In this video, you’ll discover one of the most fundamental ideas in calculus — the derivative. We’ll connect derivatives to slopes of tangent lines, equations of tangent lines, and velocity, giving you both geometric and real-world perspectives. Step-by-step examples will show how limits are used to define and calculate derivatives.
2.8 The Derivative as a Function
In this video, you’ll go beyond finding a single derivative value and learn how to think of the derivative as its own function. We’ll explore how to compute derivatives using the limit definition, how to graph a derivative based on the original function, and what it means for a function to be differentiable. We’ll also introduce higher-order derivatives and what they represent.
Chapter 3: Differentiation Rules
3.1 Derivatives of Polynomials and Exponential Functions
In this video, you’ll master the core differentiation rules for polynomials and exponential functions. We’ll start with the power rule — one of the most important tools for finding derivatives quickly — and then cover the constant multiple, sum, and difference rules. Finally, we’ll learn how to differentiate the natural exponential function and apply these rules to solve example problems.
3.2 The Product and Quotient Rules
In this video, you’ll learn two powerful differentiation rules for handling products and quotients of functions. We’ll break down each rule, go through worked-out examples, and practice applying them step by step.
3.3 Derivatives of Trigonometric Functions
In this video, you’ll learn how to find the derivatives of all six trigonometric functions. We’ll start with the fundamental trigonometric limits that form the basis for deriving the derivatives of sine and cosine, then work through the derivations step by step. Finally, we’ll summarize the derivatives of all six trig functions and solve practice problems.
3.4 The Chain Rule
In this video, you’ll learn how to use the chain rule to differentiate composite functions. We’ll review how to identify inner and outer functions, introduce the chain rule formulas, and then apply them to a series of step-by-step derivative examples, including functions with multiple layers.
3.5 Implicit Differentiation and Derivatives of Inverse Trigonometric Functions
In this video, you’ll learn how to find derivatives of equations where y is not given explicitly as a function of x. We’ll compare explicit and implicit functions, outline the method for implicit differentiation, and solve multiple examples, including tangent lines and higher-order derivatives.
In this video, you’ll learn the derivative formulas for all six inverse trigonometric functions. We’ll derive them step by step, then apply them in worked-out examples, including problems that combine inverse trig functions with the chain rule.
3.6 Derivatives of Logarithmic Functions
In this video, you’ll learn the derivative formulas for logarithmic functions and how to apply them step by step. We’ll also introduce logarithmic differentiation — a powerful technique for differentiating products, quotients, and expressions with both the base and exponent as functions of x.
3.7 Rates of Change in the Natural and Social Sciences
In this video, you’ll explore one of the most important applications of calculus — exponential growth and decay. We’ll derive the model, explain what the constant k represents, and work through examples from biology, physics, and everyday life.
3.8 Exponential Growth and Decay
In this video, you’ll explore one of the most important applications of calculus — exponential growth and decay. We’ll derive the model, explain what the constant k represents, and work through examples from biology, physics, and everyday life.
3.9 Related Rates
In this video, you’ll learn how to approach related rates problems step by step. We’ll review the main strategy, go over the standard formulas that appear most often, and solve eight classic related rates examples covering geometry, motion, and trigonometry.
3.10 Linear Approximations and Differentials
In this video, you’ll learn how to use tangent lines to approximate complicated functions and apply differentials to estimate error. We’ll cover the linearization formula, work through examples, and see how to apply these techniques to real-world problems.3.11 Hyperbolic Functions
