Introduction to Calculus

Calculus is a branch of mathematics dealing with continuous change, divided into differential and integral calculus.
Differential calculus focuses on rates of change and slopes of curves.
Integral calculus focuses on accumulating quantities and areas under curves.

Differential Calculus

Limits: A fundamental concept, describing function behavior as input approaches a value; crucial for continuity and derivatives.
Derivatives: The instantaneous rate of change at a point, representing the tangent line's slope.
Rules of Differentiation: Power rule, product rule, quotient rule, and chain rule efficiently calculate derivatives of complex functions.
Interpretations of Derivatives: Real-world applications, like velocity and acceleration.
Applications of Derivatives: Optimization (maxima/minima), curve sketching, and related rates problems.

Integral Calculus

Integrals: The inverse operation of differentiation, representing accumulated quantity over an interval.
Indefinite Integrals: Represents a family of functions differing by a constant (C).
Definite Integrals: Numerical value of the area under a curve over a specific interval, evaluated by finding the antiderivative and evaluating at interval endpoints.
Fundamental Theorem of Calculus: Connects differentiation and integration; differentiation and integration are inverse operations.
Applications of Integrals: Calculating areas, volumes, work, and average values.

Fundamental Concepts and Techniques

Continuity: A function is continuous at a point if the limit exists and equals the function's value. Essential for applying calculus concepts.
Mean Value Theorem: Relates average and instantaneous rates of change.
Intermediate Value Theorem: A continuous function on a closed interval takes on all values between its endpoints.
L'Hôpital's Rule: Evaluates indeterminate forms (0/0 or ∞/∞) in limits.

Functions and Graphs

Different Types of Functions: Polynomials, exponentials, logarithms, and trigonometric functions (sin, cos, tan).
Graphing Functions: Essential to visualize and analyze function behavior.
Properties of Graphs: Increasing/decreasing intervals, concavity, and points of inflection are analyzed using calculus.
Analyzing functions: Calculus tools used to determine local maxima, minima, and critical points.

Applications in Other Fields

Physics: Describing motion, forces, and energy.
Engineering: Designing structures, analyzing systems, and optimizing processes.
Economics: Modeling growth, cost, and profit functions.
Computer Science: Machine learning, optimization algorithms, and signal processing.
