Study Notes

Cálculo

Definición: Rama de las matemáticas que estudia el cambio y la acumulación, a través de conceptos como derivadas e integrales.
Principales ramas:
- Cálculo Diferencial: Estudia la tasa de cambio de una función.
  - Derivada: Representa la pendiente de la tangente a una curva en un punto.
  - Reglas de derivación:
    - Regla del producto
    - Regla del cociente
    - Regla de la cadena
  - Aplicaciones:
    - Optimización (máximos y mínimos)
    - Análisis de funciones (crecimiento y decrecimiento)
- Cálculo Integral: Se centra en la acumulación de cantidades y el área bajo una curva.
  - Integral definida: Calcula el área bajo la curva de una función en un intervalo.
  - Integral indefinida: Representa la familia de funciones cuya derivada es la función dada.
  - Teorema Fundamental del Cálculo: Conecta las derivadas y las integrales.
  - Métodos de integración:
    - Sustitución
    - Integración por partes
    - Integrales impropias
Conceptos clave:
- Límites: Fundamental para definir derivadas e integrales.
  - Límite de una función: Comportamiento de f(x) cuando x se aproxima a un valor.
- Continuidad: Una función es continua si no presenta saltos o discontinuidades en su dominio.
Aplicaciones del cálculo:
- Física (movimiento, velocidad, aceleración)
- Economía (costos marginales, maximización de beneficios)
- Biología (crecimiento poblacional, modelos de difusión)
Teoremas importantes:
- Teorema de Rolle: Si una función es continua en un intervalo cerrado y derivable en el abierto, existe al menos un punto donde la derivada es cero.
- Teorema de Mean Value: Relaciona el cambio promedio sobre un intervalo con el cambio instantáneo en al menos un punto del intervalo.

Definition and Main Branches

Calculus studies change and accumulation using derivatives and integrals.
Differential Calculus: Focuses on the rate of change of functions.
- Derivative: Indicates the slope of the tangent line at a point on a curve.
- Rules of Differentiation: Include product rule, quotient rule, and chain rule.
- Applications: Used for optimization (finding maxima and minima) and function analysis (growth and decay).
Integral Calculus: Concentrates on accumulation and the area under curves.
- Definite Integral: Measures the area under a function within a specified interval.
- Indefinite Integral: Represents a family of functions for which the given function is the derivative.
- Fundamental Theorem of Calculus: Establishes a connection between derivatives and integrals.
- Methods of Integration: Techniques include substitution, integration by parts, and improper integrals.

Key Concepts

Limits: Essential for defining derivatives and integrals.
- Limit of a Function: Describes the behavior of f(x) as x approaches a specific value.
Continuity: A function is continuous if it has no jumps or discontinuities within its domain.

Applications of Calculus

Applied in physics for motion, velocity, and acceleration.
In economics, utilized for marginal costs and maximizing profits.
In biology, assists in modeling population growth and diffusion processes.

Important Theorems

Rolle's Theorem: States that if a function is continuous on a closed interval and differentiable on the open interval, there is at least one point where the derivative equals zero.
Mean Value Theorem: Connects average change over an interval to instantaneous change at some point within that interval.
