The radius of convergence:
Let be a power series, and then the power series converges absolutely if and diverges if
The interval of convergence:
Every power series has a radius of convergence. The interval is the interval of convergence for a power series.
The Taylor series about is called the Maclaurin Series, i.e. for every
The Lagrange form of the Remainder:
If exists and is continuous on I then for any x in I, there exists a point between c and x such that

"Title" Tutorial Summary :
Taylor polynomials are discussed with the help of power series and the radius of convergence principle. Power series are important to the development of the radius and the interval of convergence ideas. Examples are given to show the radius and the interval of convergence principles.
The Taylor Series idea is created from the differentiation of a particular function a countable number of times. Polynomials are approximated using Taylor series and Maclaurin Series. The error of series is given with the use of Lagrange multipliers and how a new series is created from a given series.
