What is the Taylor Series? (Keyword: Taylor Series Explained)
The Taylor Series is a representation of a function as an infinite sum of terms, each calculated from the function’s derivatives at a single point. It’s expressed as:
f(x) = f(a) + f’(a)(x-a) + f”(a)(x-a)^2⁄2! + f”‘(a)(x-a)^3⁄3! + …
For the function 1/x, the Taylor Series expansion around a = 1 is particularly interesting. It helps us approximate the function near this point and understand its behavior.
