Understanding the Taylor Series

The Taylor series is an infinite sum of terms that are expressed in terms of the function's derivatives at a single point. It approximates a function as a polynomial. The Taylor series of a function \( f(x) \) around the point \( x = a \) is given by:

\[ f(x) = \sum_{n=0}^{\infty} \frac{f^{(n)}(a)}{n!} (x - a)^n \]

Key Concepts

• Expansion Point: The point \( a \) around which the function is expanded.
• Order of Expansion: The number of terms \( n \) used in the series, affecting the approximation's accuracy.
• Derivatives: The \( n \)-th derivative \( f^{(n)}(a) \) is evaluated at the expansion point.
