Integration - Indefinite Integrals

Indefinite Integrals

Basic Integration Rules and Formulas

An indefinite integral represents a family of functions whose derivative is the integrand. It is written with the integral symbol and includes a constant of integration \( C \), because differentiation of a constant is zero.

Standard Indefinite Integrals

\[ \int f(x) \, dx = F(x) + C, \quad \text{where } F'(x) = f(x) \]
\[ \int dx = x + C \]
\[ \int k f(x) \, dx = k \int f(x) \, dx \] — Constant multiple rule
\[ \int (u + v + w) \, dx = \int u \, dx + \int v \, dx + \int w \, dx \] — Sum rule
\[ \int u \, dv = uv - \int v \, du \] — Integration by parts
\[ \int f(kx) \, dx = \frac{1}{k} \int f(x) \, dx \] — Change of variable rule
\[ \int x^m \, dx = \frac{x^{m+1}}{m+1} + C \quad (m \neq -1) \]
\[ \int (ax + b)^n \, dx = \frac{(ax + b)^{n+1}}{a(n+1)} + C \quad (n \neq -1) \]
\[ \int e^x \, dx = e^x + C \]
\[ \int k^x \, dx = \frac{k^x}{\ln k} + C \quad (k > 0, k \neq 1) \]

Terminology

Integrand: The function being integrated.
Antiderivative: A function whose derivative equals the integrand.
Indefinite Integral: A general form of antiderivatives including the constant of integration \( C \).
Integration by Parts: A technique based on the product rule for derivatives.
Change of Variable: A method to simplify integration using substitution.

Applications

Finding original functions from rate-of-change data (velocity → position, etc.).
Calculating displacement, total growth, or area under a curve in general form.
Used in physics for work, energy, and electric potential problems.
Important in machine learning for regularization and loss function adjustments.
Forms the basis for solving differential equations analytically.
