Calculus I: Core Topics and Learning Objectives

Core Course Topics

1. Definition of Limits

The concept of a limit is foundational in calculus, describing the behavior of a function as its input approaches a particular value. Limits are essential for defining continuity, derivatives, and integrals.

• Numerical, algebraic, and graphical methods: Limits can be evaluated using tables of values, algebraic manipulation, or by analyzing graphs.

• One-sided and two-sided limits: Understanding the difference between approaching from the left or right.

• Infinite limits and limits at infinity: Describing unbounded behavior or end behavior of functions.

2. Continuity

Continuity ensures that a function behaves predictably without jumps or breaks. It is a prerequisite for differentiability.

• Definition of continuity: A function is continuous at a point if the limit exists and equals the function value at that point.

• Types of discontinuities: Removable, jump, and infinite discontinuities.

3. Definition of the Derivative

The derivative measures the instantaneous rate of change of a function. It is defined as the limit of the average rate of change as the interval approaches zero.

• Limit definition: $f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}$

• Interpretation: Slope of the tangent line to the curve at a point.

4. Applications of the Derivative

Derivatives are used to analyze and solve real-world problems involving rates of change, optimization, and motion.

• Related rates: Finding how one quantity changes with respect to another.

• Optimization: Maximizing or minimizing functions in applied contexts.

• Graph analysis: Using derivatives to determine intervals of increase/decrease, concavity, and inflection points.

5. Techniques of Differentiation

Various rules and techniques are used to differentiate complex functions efficiently.

• Product Rule: $\frac{d}{dx}[u(x)v(x)] = u'(x)v(x) + u(x)v'(x)$

• Quotient Rule: $\frac{d}{dx}\left[\frac{u(x)}{v(x)}\right] = \frac{u'(x)v(x) - u(x)v'(x)}{[v(x)]^2}$

• Chain Rule: $\frac{d}{dx}f(g(x)) = f'(g(x)) \cdot g'(x)$

• Differentiation of trigonometric, exponential, and logarithmic functions.

6. Introduction to Integration

Integration is the reverse process of differentiation and is used to find areas under curves and solve accumulation problems.

• Antiderivatives: Functions whose derivative is the given function.

• Definite and indefinite integrals: $\int_a^b f(x)dx$ and $\int f(x)dx$

• Fundamental Theorem of Calculus: Connects differentiation and integration.
