Introduction to Calculus: Course Outline and Key Topics

Introduction to Calculus

This document provides an overview of the main topics covered in a college-level Calculus course. The structure aligns with standard Calculus curricula, including limits, derivatives, integrals, and their applications. The course is designed to prepare students for exams such as the CLEP, with a balance between differential and integral calculus, and includes foundational concepts in algebraic, trigonometric, exponential, and logarithmic functions.

1. Limits

• Definition of a Limit: Understanding how a function behaves as its input approaches a particular value.

• Computing Basic Limits: Techniques for evaluating limits analytically.

• Continuity: A function is continuous if its limit at a point equals its value at that point.

• Squeeze Theorem: Used to find limits of functions trapped between two other functions.

2. Derivatives

• Theory of the Derivative: The derivative measures the instantaneous rate of change of a function.

• Tangent Lines: The slope of the tangent line at a point is the derivative at that point.

• Definition of Derivative: $f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}$

• Rates of Change: Applications in physics and other sciences.

• Derivative Rules: Includes product, quotient, and chain rules.

• Fundamental Derivative Rules: Basic rules for differentiating sums, products, and quotients.

• Chain Rule: Used for differentiating composite functions.

• Derivatives of Exponential and Logarithmic Functions: $\frac{d}{dx}e^x = e^x$, $\frac{d}{dx}\ln x = \frac{1}{x}$

• Trigonometric Derivatives: $\frac{d}{dx}\sin x = \cos x$, $\frac{d}{dx}\cos x = -\sin x$

• Derivatives of Inverse Trigonometric Functions: $\frac{d}{dx}\arcsin x = \frac{1}{\sqrt{1-x^2}}$

• Higher Order Derivatives: Second and higher derivatives represent rates of change of rates of change.

• Implicit Differentiation: Differentiating equations not solved for y explicitly.

• L'Hôpital's Rule: Used to evaluate indeterminate forms.

• Classic Theoretical Results: Includes the Mean Value Theorem and Rolle's Theorem.

3. Applications of the Derivative

• Plotting with Derivatives: Using derivatives to analyze and sketch graphs.

• Increasing and Decreasing Functions: Determined by the sign of the first derivative.

• Extrema: Local maxima and minima found using critical points.

• Concavity: Determined by the sign of the second derivative.

• Rate of Change: Applications in motion, growth, and decay.

• Physics Problems: Applying derivatives to solve real-world problems in physics.

4. Integrals

• Theory of the Integral: The integral represents the accumulation of quantities, such as area under a curve.

• Antidifferentiation: The process of finding a function whose derivative is the given function.

• Definite Integral: $\int_a^b f(x)\,dx$ gives the net area under $f(x)$ from $a$ to $b$.

• Riemann Sums: Approximating the area under a curve by summing areas of rectangles.

• Fundamental Theorem of Calculus: Connects differentiation and integration: $\frac{d}{dx}\int_a^x f(t)dt = f(x)$

• Basic Integral Rules: Includes linearity, substitution, and integration by parts.

• U-Substitution: A method for integrating composite functions.

5. Applications of the Integral

• Area Under Curves: Calculating the area between a function and the x-axis.

• Average Value: The average value of $f(x)$ on $[a, b]$ is $\frac{1}{b-a}\int_a^b f(x)dx$

• Growth and Decay Models: Exponential models for population growth and radioactive decay.

• Return to Physics: Applications of integrals in physics, such as work and energy.
