Integration is a calculus technique used to find the area under a curve or to determine the value of an antiderivative. It involves finding a function that, when differentiated, gives the original function. This process is also known as finding the indefinite integral, and the result of the integration is called the antiderivative or the primitive function. Integration is used in various fields including physics, economics, engineering, and statistics. It is an essential tool in solving complex mathematical problems and modeling real-world scenarios. Some common integration techniques include substitution, integration by parts, partial fractions, and trigonometric substitution.
