linearization

Linearization is a mathematical method used to approximate a complex, curved function near a specific point with a straight line. Think of it as zooming in very close to a small section of a curve so that, within that tiny area, the curve looks almost like a straight line. This makes it easier to analyze or estimate the function’s value near that point. Essentially, linearization simplifies complicated functions into manageable linear equations for practical calculations, especially when precise values are difficult to compute directly.
