Numerical evaluation refers to the process of calculating the value of mathematical expressions or functions using numerical methods. This approach is often employed when exact solutions are difficult or impossible to obtain analytically. Techniques such as approximation, interpolation, and numerical integration are commonly used to achieve accurate results. In various fields like engineering, finance, and science, numerical evaluation plays a crucial role in solving complex problems. By converting continuous functions into discrete values, it allows for the analysis and simulation of real-world scenarios, making it an essential tool for researchers and professionals alike.
