Integral Symbol ∫
The integral is a fundamental concept in calculus that represents the accumulation of quantities. The integral symbol is used to denote this mathematical operation.
Definition
The integral of a function f(x) with respect to x is denoted by the symbol ∫ and is expressed as ∫ f(x) dx, where dx indicates the variable of integration.
Representation in HTML
In HTML, the integral symbol can be represented using the HTML entity ∫ or by the character itself <int>.
Usage in Mathematics
Integrals are used to calculate various mathematical quantities, including areas under curves, volumes of solids, and solutions to differential equations.
Example
The integral of a function f(x) = x^2 with respect to x from 0 to 1 is represented as ∫ (x^2) dx from 0 to 1 and evaluates to ⅓.
Understanding the integral symbol is essential for mastering calculus and its applications in various scientific and engineering fields.
