Numerical integration (quadrature)

Numerical integration, often referred to as quadrature, is a computational technique used to approximate the value of integrals when they cannot be solved analytically or when an exact solution is impractical. It involves evaluating the integral of a function using discrete points, rather than calculating the area under the curve in a continuous manner. ### Key Concepts: 1. **Integration Basics**: - The integral of a function represents the area under its curve over a specified interval.
