The online Taylor polynomial calculator is capable of calculating the polynomial approximation of a function by using the Taylor series.
To use the Taylor series expansion calculator you must follow these steps:
The Taylor series is a power series that extends to infinity, where each of the addends is raised to a power greater than the antecedent.
Each element of the Taylor series corresponds to the nth derivative of the function f evaluated at point a, between the factorial of n (n!), and all this, multiplied by (x-a) raised to the power n.
In formal terms, the Taylor series has the following form:
The “official” definition of the Taylor polynomial is that it is a polynomial approximation of a function n times differentiable at an exact point. This means that the Taylor Polynomial is nothing more than the finite sum of local derivatives that are evaluated at a specific point.
When making the graphical representation of a Taylor polynomial, it can be seen that, as the degree of the polynomial increases, it approaches more precisely the function it represents around the point studied.
The difference between a series and a Taylor polynomial is that, in the first case, we are talking about an infinite sequence, while in the second it is a finite series.
Thus, the Taylor polynomial can be defined as a polynomial approximation of a function n times differentiable at a specific point (a).
