👉 Integrability is a mathematical concept that describes how a function or a sequence of functions can be integrated. Integrand refers to the input or variable for which we are integrating, and the derivative of the integrand represents the rate of change of the integrand with respect to its input. In other words, integrability means that a function is continuous at every point in its domain, i.e., it has an infinite number of antiderivatives. This is because the derivative of any continuous
