Approximate (Numerical) IntegrationCalculus IIWhen do we use approximate integration?Situations that make it impossible to find the exact value of a definite integral:Finding the antiderivative is difficult or even impossible. Therefore there is no way to apply the Fundamental Theory of Calculus.The function is determined from a scientific experiment through collection of data or instrument readings. Example:Methods for Approximate Integration
