Dear Anurag

integral may also refer to the notion of antiderivative, a function F whose derivative is the given function ƒ

If a function has an integral, it is said to be integrable. The function for which the integral is calculated is called the integrand. The region over which a function is being integrated is called the domain of integration

The simplest case, the integral of a real-valued function f of one real variable x on the interval [a, b], is denoted by

$\int_a^b f(x)\,dx .$

The ∫ sign represents integration; a and b are the lower limit and upper limit, respectively, of integration, defining the domain of integration; f is the integrand, to be evaluated as x varies over the interval [a,b]; and dx is the variable of integration

All the best.
