Whether you are a student a teacher, or a researcher you need a Taylor expansion calculator to get instant solutions of infinite functions at its center point, because it is widely used in various scientific fields like engineering, physics, economics, and many more fields.

Additionally, For even more advanced mathematical computations involving singularities and complex functions, you can go through our laurent expansion calculator. This calculator is designed to compute Laurent series expansions, providing valuable insights into the behavior of complex functions in the complex plane.

Define the Taylor Series

Taylor series is a form of power series that gives the expansion of a function f(x) in the central region of a point that tells you a function is continuous or differentiated at that specific point.

The Taylor series expansion allows us to approximate a function using a polynomial, which can be easier to manipulate and evaluate than the original function. It is widely used in various fields of mathematics, physics, engineering, and other sciences for solving differential equations, numerical analysis, and modeling complex systems

Equation Behind Taylor Polynomial Calculator

The equation of the Taylor series used by the Taylor series calculator to solve the problems is given below,

$$ f(x) \;=\; \sum_{n=0}^{\infty} \frac{f^{(n)} (a)}{n!} (x - a)^n \;=\; f(a) + f’(a)(x - a) + \frac{f’’(a)}{2!} (x - a)^2 + \frac{f’’’(a)}{3!} (x - a)^3 + … + \frac{f^{(n)}(a)}{n!} (x - a)^n + … $$

For the Taylor series a sum of power series of differentiation function into n number of times that is f(x), and a is the central point f(a).

For functions approximated around the point x=0, also known as the Maclaurin series, you can be use our maclaurin series calculator. This calculator specializes in computing Taylor series expansions centered at the origin, providing efficient approximations for a wide range of functions.

Working Procedure of Taylor Expansion Calculator

Taylor series expansion calculator can solve complex functions at the given point as an infinite series, where the terms show the value of the derivative at a one-variable only. It gives you a series expansion of specific order of the polynomial function.

You just need to enter the function with its central point in the Taylor approximation calculator. It checks the nature of infinite series and then applies the differentiation rule on a given function concerning variable in n number of times as n=1,2,3.. that you specified the number for differentiation.

Now enter the center point a in f(x)=f(a) then add all n number of derivation functions to make a series. After calculation, this Taylor polynomials calculator provides you answers in the form of the sum of a series like a polynomial which helps you to understand the Taylor series concept easily.

Solved Example of Taylor Series

Taylor series can be determined by using the Taylor series calculator but it is also essential to solve it manually. So here is a manual example of the Taylor series with steps, where each step is explained in detail.


Find the Taylor series for the natural logarithm function ln(x) centered at a = 1:


$$ f(1) \;=\; ln(1) \;=\; 0 $$

$$ f’(x) \;=\; \frac{1}{x} . f’(1) \;=\; \frac{1}{1} \;=\; 1 $$

$$ f’’(x) \;=\; -\frac{1}{x^2} . f’’(1) \;=\; -\frac{1}{1^2} \;=\; -1 $$

$$ f’’’(x) \;=\; \frac{2}{x^3} . f’’’(1) \;=\; \frac{2}{1^3} \;=\; 2 $$

Now construct the Taylor series around x = 1:

$$ ln(x) \;=\; 0 + (1)(x - 1) + \frac{-1}{2!} (x - 1)^2 + \frac{2}{3!} (x - 1)^3 + … $$


$$ ln(x) \;=\; (x - 1) - \frac{1}{2} (x - 1)^2 + \frac{1}{3} (x - 1)^3 + … $$

The coefficients of the series pattern allow us to write that,

$$ ln(x) \;=\; \sum_{n=1}^{\infty} \frac{(-1)^{n - 1}}{n} (x - 1)^n $$

So, this is the taylor series expansion centered at a = 1, which represents the natural logarithm involving powers of x - 1.
